I have the 16 gb s4 and its great an all that we have a micro sd slot but I have found the whole concept unreliable at best. For one I have had 2 different sd cards fail. One gskill 32gb class 10 and a samsung 64 gb fail. All my pictures, roms and app gone. I back them up but still not being able to trust them is a huge concern. And the 64 gb seemed like a great idea except you have to format it fat32 to get recovery to view it, and when I did that my phone constantly wanted to format it back exfat. I pretty much have no option to get a 32 gig with a mdk rom either. Just my rant as I figure out how to rma both of these cards.

Sounds like you've just had some bad luck. I've been using a 64gb Class 10 SanDisk formatted for exFat and it's worked fine so far (I even use Folder Mount to move a bunch of stuff from internal to external).
Surprised the Samsung card failed on you.
Btw, the exfat/64gb issue only exits for some implementations. I'm running Barebones ME7 rom w/ktoonsez kernel and Phils/CWM recovery and both the recovery and the kernel support 64gb exFat.

you might be just out of luck
I'm using a sanDisk Ultra 64GB on my S4 and everything works fine (FAT32 formatted)
I've never had any SD card fail me. Never heard of gskill and there is the possibility that the samsung sd card you got was a fake...depending on where you got it. I've used PNY, Samsung, and SanDisk sd cards and all have lasted me a long time through heavy usage.
I have a 64 gig sd card and never had an issue. I use it all the time.
first thing I did was wipe and format it in twrp recovery to whatever format it wanted.
golden.
Two cards failing? Unbelievable bad luck (I have never had a storage device of any type fail...not even platter hard drives...and I'm 43 and have had my own pc of some sort for 25 years), a bad card reader in the phone, or operator error.
I'm thinking bad card reader in the phone.

During last week of owning my S3, i took my samsung 32gb microsd out when i replaced my screen , upon getting it all finished and putting it back in, the sd was dead. I feel you on that though, sucks to loose all the pictures. Wouldnt get recognized on either of my pcs, Old 8mp digital cam tried to format it but couldnt do it.
I bought an authentic sandisk 32gb microsd to replace it, so far so good.

You need to go buy a lottery ticket, hdd/ssd/ram are the number one thin besides power supplies that die in computers. I have had probably a 10 percent failure amomg desktop ssd's since they first got popular. I build alot of computers and its definitely a brand/product line importance.

I had an almost identical issue a while back. I used to always use a Sandisk 32gb class 10 card in my S3 and other devices. I used the same card for 3 or 4 years. When I got my S4 I decided to make the jump to a 64 gb card due to the small internal storage. So I went out and bought a 64 gb Class 10 Sandisk since I have always had good experiences with their cards. First thing I popped it into my computer and re-formatted it to Fat32. Then I plugged it into my phone and it seemed to work fine for a while, then randomly it would unmount itself and remount for no apparent reason. It would do it randomly 3 or 4 times a day. I tried wiping and reformatting to fat32 again, tried exfat, and even NTFS. Failing all that I took it back and exchanged it for another identical one. Same EXACT issue... So I gave it one last shot and exchanged one more time. At this point the ladies at Wal-mart are looking at me sideways like I'm running a scam or something. Lol. Anyways, the third one worked spectatularly. I haven't had one single unmount with it and I have all the storage I could possible need. I keep two Nandroid backups on my memory at all times (and with the S4 they are HUGE, 4gbs or better) and I have like 15 gbs of music, not to mention other miscellaneous files and apks and such, and I still have 30 gbs left.
I say just try it again man. Third times a charm. And I personally would always recommend Sandisk. I have never had one fail me and lost my data or anything. They have always worked for me.

Did you format back to Fat32 on your third try? I am going through the same thing and I am on my second card, waiting for the third to come in the mail. The first one I did Fat32 and out of the blue it would get extremely hot, and then say safe to remove card without me doing anything.
The second one, I left as is, copied everything over and left it exFat. That lasted about a week and then stuff started disappearing in gallery view, BUT it was there in Root explorer. The card it a Sandisk 64 gb Mobile Ultra.

Yeah mine was the same issue, only I didn't notice any heat to speak of. And yes on the first card I got, I used a windows program called fat32format and formatted it before ever even putting it in my phone. It would intermittently unmount and remount exactly as you are describing. So I took it out, wiped and reformatted to fat32 again. Still did the same thing. So as a last ditch I tried formatting to exfat. My phone and recovery both read the card just fine, it would just unmount randomly, or when I was either listening to music or viewing my gallery (something that required high read speeds) and it would unmount and interrupt it. So, thinkiing that it was just a faulty card I exchanged for a identical new one. Same issue. This time I used a different program to reformat to fat32, I forget the name of it, but it was a command line based reformatting tool for windows. I used it and had that same problem even after several reformats. At this point I was starting to wonder if it was a problem with my phone's SD card slot., So as a last effort I did one more exhange, reformatted using the command line tool and haven't had one single unmount since then, and I have ALOT of stuff on it. I would just suggest keep trying. I think that Galaxy phones are just sensitive to card reading and if you don't have an absolutely perfect one it will have problems. Or who knows, maybe I just had that off chance of one in a million by getting two bad cards in a row. Either way, I would suggest reading this thread (if you haven't already): http://forum.xda-developers.com/showthread.php?t=1773735
Use the first method on your new card. That I think is the most foolproof formatting method. Good luck, you will find the right card eventually.
Thank you!! Ill give it a shot tomorrow when the new card arrives. I appreciate that thread reference too! Fingers are crossed.

Yeah no problem. Good luck
There may be a pattern....
But I am not sure exactly what it is.
I have two nearly identical SG4s (1 for + 1 for my wife) and both have the 64GB SanDisk Micro Ultra. One phone is completely stock (my wife's) and the card is lightly used and formatted exFat. Mine is rooted and Roomed (Synergy) with TiBkup and CWM. Like other folks, I had to reformat the card to Fat32 in order to work with CWM.
As far as I can tell, she never sees any un-mount/re-mount messages on her phone but it is lightly used and she might not notice. I DO see occasional un-mount/re-mount messages, but I cannot tie it to a specific program or event. Sometimes happens right after reboot. Sometimes happens when I launch TiBkup. But goes for days with no issues.
I have never lost any data or noticed any performance hits, but now I am worried that I might.
Guess it is time to take more backups of the backups...
I have had lots of computer equipment fail over the years, but never exactly like this...
Well I followed everything nicholi2789 suggested and low and behold my card is actually working good. It does not get hot when reading ( not as hot as the other 2 anyway) and I can see a big time difference in speed. So I guess its true, the third times a charm in the case of these 64 gb Sandisk Ultra cards.
Big thanks again to nicholi2789 for pointing me in the right direction!
I bought a SanDisk Microsdxc class 10 64gb and let the phone format. It's working great. It has the fastest speeds out of all I've seen.

Let me start out by saying that I have searched for any threads that have covered this, and have come up empty.
This has happened twice to me in the last two months. Running task650's V.9, which is an awesome ROM. I've got a Lexar Class 10 32gb card. Twice in two months have I booted up and the media scanner would show a broken sd card notice. I tried booting the phone without the card, and then re-installed the card. Same notice of bad sd card on boot.
At this point I took the card and stuck it in a laptop, which generated a "can not open due to corrupt or unreadable file" and "reformat drive" or something like that. I was forced to format, losing photos, vids, and TiBu folder. I synced to Dropbox and got the backup folder re-installed.
Any ideas about what could have corrupted the card? I suppose the card could be damaged. I paid good bucks, as it is not a low end card. Replace the card? Any guidance would be appreciated.
I have a Lexar Class 10 32GB card. Same issue, after first time reformatted and same thing happened a week or two later.
I did an RMA with Lexar, think there is a 1 year warranty. Got a new card, been working fine the past several months.
Ok. Thanks for the input. I've got a Kingston Class 10 on the way.
I was hoping it wasn't in the phone hardware.
Thanks, I just reminded myself to do a backup of that card itself to my PC.
Sorry to hear about your problem though.

Yeah, I lost some New Years day photos and vids with my wife. I'll NEVER find her in that good of a mood again!
It makes me wonder about my decision to place my TiBu folder on the external card, along with Nandroid backups. True, it syncs to Drop Box for TiBu but do I need the extra headache of wondering if my card is going to get smoked again? I suppose I should be backing it all up to pc..
I'm not sure but it seems to be a problem with the phone and class 10 cards.
My first one was a 16gb class 10 micro sd that one day just decided to stop working (lasted a month or so). Couldn't access it via the phone or PC.
So I went out and got a 32gb class 10 and after a month or so again it stopped working
Knowing this I refused to buy a class 10 card again. I went to Walmart and got the cheapest 32gb micro sd (Sandisk class 4) and so far so good. no problems at all
Lost everything I had too on the first 2 cards so learned the hard way to do backups to my PC.
Not the class, it's probably the brand. Some brands have terrible quality control, especially if you go for a cheaper one. I have one from Amazon Basic and it works just fine. My brother uses one from SanDisk with zero problem.
Class 10 is also newer. The technology to manufacture these is not that old. I suspect some manufacturers still need to refine their process.

Got a similar problem here.
Transcend Class 10 32GB Card
Works in PC, HTC Desire - no probs.
Put in Galaxy S2, it starts Media Scanning, a few seconds later reports SD Card Damaged, requires formatting.
It's right - take it back out (again, umpteenth time!), put it in PC or HTC - card is "damaged". (Nothing permanent, can reformat.)
Samsung support claim to not know anything - mind you they "play dumb" about the camera "pink spot" issue, until you challenge them to get real...
Oh, dear!

Buy a 500gb external hard drive for like 50 bucks they're cheap now. Backup everything to it once a week. Never lose data. Profit.

Sounds like a brand issue, but have you ever tried checking the drive for errors?
Given that even your PC gives you a "damaged" message, it may not work. Once inserted, go to "My Computer," get to properties, and check for errors (enable the "automatically fix file system errors" option). In the past, this has corrected "corrupted" SD cards for me.

The only corruptions I have experienced on this phone were when using MTP to transfer files from the PC. Since I stopped using MTP and use only USB Storage mounting, I have not had any more problems.
I've actually experienced this twice. Both times flashing to AOKP. I'm not blaming AOKP but just saying. The first time even my PC wouldn't read it and it needed to be reformatted. The second time my pc could read it and after nandroiding back to shostock2 it was fine.

Thanks for all the ideas guys!
That used to happen to me, got very frustrated because I could never copy things to my flash cards. Turns out the problem was my card reader. Try getting one of the USB ones that can actually read SDXC. I don't have one, so what I did is put it in the phone, then connect via USB to the computer in mass storage mode and it worked great.
I had the 64GB SDXC as well, it at first seemed to work, but don't be surprised if it stops working. Motorola, and I believe stock Android do not support SDXC yet. I have a somewhat detailed thread here: http://www.droidforums.net/forum/dr...d-cards-hd-maxx-hd-class-10-32gb-vs-64gb.html
When I got my card, popped it in, it formatted correctly, and seemed to work fine. As I started to put it through its paces it started to just not work. On ICS when you used the Storage option to transfer media to the SD card, it would stop halfway through and throw out errors. Eventually certain apps would stop writing/seeing the card like backup apps etc..
Be careful going forward, and test it hardcore. Transfer files back and forth, I always had issues with movie files. See if Root Explorer or other explorer apps can see it, see if Titanium Backup or My Backup Pro/SMS Backup can see and write to the card.
And yes, I did not get a dud, its works in other non-Android devices and works and tests perfectly in multiple computers. Just be cautious.

These are all the same symptoms I'm having. Well, it looks like Motorola actually had testing and reasoning behind "supports up to 32GB" :-| That'll teach us to think we're smarter than the factory QA guys...
Still though, it's a little disappointing.

Indeed, some of the Sammy devices support the SDXC 64GB card, but I think that's baked into TouchWiz. Hopefully as SDXC gets more popular it will become supported by Android all together. It would be nice to have at least half of my music library on my car so I don't have to stream all the time lol.
Confirmed working with a 64GB SDXC, works pretty well actually, now I'll never run out of space.
I bought 2 64GB micro SDXC cards. One for my Xoom and the other for my upcoming XT925. My Xoom was unable to format it so I used EaseUS Partition Master to format my 64GB cards as FAT32 partitions. So far so good...
I tried my sandisk SDXC 64Gb yesterday with no luck. It was formated to exFat though. I will try EaseUS tonight and try formatting it to Fat32.

I have a 64GB card. No issues.Took the card out of my Maxx.
I bought a 64 sandisk sdxc class 10 and tried it in the phone. Didn't work. Formatted to fat32 with a partition program, still wouldn't work. Got fed up, deleted all the partitions, threw it in the phone and itr was recognized, but blank. Had the phone format it, and it works. Phenomenally actually. Haven't tested read/write, but I've filled it a few times over looking for problems and had none. Without looking I think I have just shy of 40 used on it right now.
You'd think Motorola would say something about that.
Got a 64gb sandisk class 10 and it's really buggy.
Forceclose/card disabled automaticly/cant see my files/Many lags.
So for me the xt925 is not compatible with it.

Hey all,
I thought I would share my findings to help others with the same issue.
Two days ago I kept catching glimpses of a card image in the notifications at the top of the screen, but it would only be for a second so I could not see what it was trying to tell me. But had a quick look and sd card seemed fine and all data was present on handset. A couple of hours later it popped up with "SD Card Unexpectedly Removed". I tried ejecting and reinserting,restarting device and turning off and removing battery all to no avail. So I did a quick search which showed this seemed to be quite a common issue, after reading many threads with people saying the sd card is corrupt or network providers saying it was software and to do a restore. I decided before all that hassle I would open the phone and check the circuitboard expecting it to be a dry solder joint. One thing I will point out that was different to some other users is the fact my sd card was not visible with the phone connected to the computer, so this may not solve all related issues.
THE FIX
Turn off phone, remove the battery, SIM card and sd card. Remove all screws except the one by the 3.5mm jack. Gently pull the white plastic trim that surrounds the card holders and battery but the top part with speaker and camera does not need removing. Once removed if you look to the left of the sd card holder you will see the ribbon that connects the sd card to the main circuit board and at the end of the ribbon is the connector. Mine was disconnected and was loose, even if yours is not loose it would be worth gently pulling it off and reconnecting it. Then reassemble in the reverse order.
This was a nice surprise in the sense it was a very simple fix. However when I mounted the sd card even directly in my pc it was not found, I assume that the loose connector floating about had probably shorted its connections and caused an issue with the sd card. After a handfuls of attempts at mounting it in my pc it was finally detected and I backed up all the data and reformatted the sd card, then copied the data back,mounted it in my phone and was happy to find it all working as expected.
I hope this information will help some of you out, as it was a simple fix to a simple issue and results from searching had no solutions, just lots of assumptions.
And what can I do
Hi
I read your articles and seem very good but u have a question.
I had the same issue and I saw that every time my phone said I hat message it creates in my sd card a folder named lost. I and then i saw that one part of my battery was going there, ti reconnect the phone with my sd card
I formatted my sd card and did all the things that I found in the Internetbut nnothing works and I just change my sd for another one I had and sincethere u ddon't have any other issue, but my computer detects very good my first sd card and I'm not sure how to fix it.
Any idea?
Regards
Recently ive just faced this issue, what I did is to insert my 32gb sd card in my PC and run CHKDISK, havent got any error while performing this, thereafter i inserted it in my phone & goodness till now this sd card error hasn't appear yet. (finger crossed).
Mine did something like this a few times and then the 32GB Sandisk class 10 card died. Couldn't get it to work in any device except Linux based Media player. Luckily managed to copy my nadroid backup and TB backup. Sent to Sandisk and they replaced it. There is already a thread about S3 damaging teh SD cards. May be the loose connection is what's causing the card to to end up dead.

Yeah,as mentioned I have seen a lot of issues about sd cards, this is the first issue I have had and thought it would be worth mentioning. There is little space when the case is together so it could easily still make contact and seem fine even if the connector has worked loose and cause all kinds of issues. As mentioned mine had the sd icon popping up every now and then before it actually failed. Some users seem to be going through a lot of sd cards with them failing on a regular bassis.
I've been using my 32gb card since my last phone which was the LG Optimus 3D it is a scandisk class 10 one. Anyway i took it out of the 3D and stuck it into my S3 i still have not had a problem. I did take it out a few times to put a rom in because i wiped my phone and didn't have a rom in the Sd card. Also i dropped my phone and replaced the whole front silver bumper bit the whole digitizer because i dropped my phone while playing basketball. It still works. It has been a year now it has been in two phones and still works great. I must be lucky..
I got mugged for the SD though i bought it last year for £60 from Argos a store in the UK. Now you can get them for half the price oh well.. I am waiting for the 128gb ones to come out so going to buy one lol..
today also my Sandisk Ultra HC I 32GB it's died, tomorrow I'll test with pc but no sign of life :crying: WTF samsung !!!
hey i have the same issue with an 32gb sd card, it was workking great and then i was getting the error about
"SD Card Unexpectedly Removed" and then i tried everything i could and my computer detect the sd card and it seems to be working normal but in my phone i have the error over and over again and it was draining my battery too, and the only thing i did was change to another 16gb sd card and this one is working.
maybe there is a problem with the 32gb sd cards
I have a 16GB Sandisk UHS-1 card and i have been getting this issue as well, and its becoming more and more frequent. Whenver it happens, the ringtones/notifications for certain apps like Gmail and Message get reset as the ringtones i set were stored in the sdcard. Also the photo frame app i have on my homescreen often resets to nothing as the pictures were also stored in the sdcard. Its really annoying because I can leave my phone sleeping, only to wake it up realizing my ringtones are all set to silent and my photo frame has been reset. At least i know its a common problem. damn you samsung!
Has anyone actually tried checking the connection on the ribbon as suggested? Mine has been fine since and works fine.
Does this method void our warranty? Seems so.

There is no way anyone would know you have opened it, the screws are all Philips instead of t6. As long as you use the correct screwdriver it won't damage the heads and will leave no sign of entery and it takes around 10 mins to complete. Or you could take it to Samsung to do but seems a lot of hassle for such a simple fix.
Also most people are rooted without concern of the warranty.
So there's no seals or stickers that are broken?

Nope, no sticker or seals and just so you know all screws to remove the back are identical, there are only two screws inside which are different but do not need removing for this. You only need a Philips screwdriver ( I used a ph00 x 40) as long as the screwdriver fits the screw well it will not damage the head. Once screws are out a flat head screwdriver or similar are helpfull to prise the back off.
Hi Guys,
A little feedback from my experience with this.
I too was experiencing the "Unexpectedly Removed" error on my 32GB Class10 Sandisk.
It was playing havok with my setup because I use a 8GB Ext4 Partition on the card, where I move 90% of my apps. (About 6GB of that is used by games + their "external" data), and it keeps my phone and FAT32 partition free for important stuff. (I use Link2SD and DirectoryBind)
The problem is, after the device wakes, Link2SD can't find any of the apps, so I can't start any of them, and I have to do a full reboot to get them back. :/
So, after searching and searching, I couldnt find a valid solution.
I tried with a 16GB class10 Samsung, and a 32GB Class10 Samsung card. Exact same setup. NO ISSUES.
Everything works perfectly.
Then I found this thread:
http://forum.xda-developers.com/showthread.php?t=1933743&page=2
Where most of them are experiencing this error with Sandisk cards.
Apparently, it's a known issue with Sandisk Cards (especially the 32GB models), and cards sold after December 2012 no longer experience this.
I have contacted Amazon.co.uk about replacing the card as it's only 2 months old, still waiting for their answer. Will update if anyones interested.
cheers

A curious question if I may.
Was this a SanDisk Ultra (UHS) card? Most (if not all) Android phones do not have a proper UHS-I driver today and, although the card is supposed to switch down automatically, that transition time can fool the OS sometimes.

I read something about UHS compatibility, so I got an SD-HC
http://www.amazon.co.uk/gp/aw/d/B007JTKLEK/ref=mp_s_a_1?qid=1357264092&sr=8-7&pi=SL75
Is it the same thing?
Hmmm. Ok, might be getting somewhere.
Any idea if these cards have an internal "power saving" system that maybe kicks in if voltage drops below a certain level?

Yes, the red and Grey SanDisk cards are UHS.
Yes, they definitely have controllers and the host device can command them (if it knows how). I know that they allow In System Programming (ISP) for updating firmware. They support auto-standby, power-off and sleep modes but am not certain if the card would switch without command. Check the SD link in my signature if you really need more info.

I tested my SanDisk 64GB Ultra card in a Note 2 and it had the same symptoms (Mine were worse, with the card locking up while playing music after a few minutes, causing mmc timeout errors in the kernel).
I switched to a Samsung 64GB Pro card and since then I haven't had any issue. It's also twice as fast.
The amount of headaches this SanDisk card gave me is insane, probably the last time I buy a card from them.
i have sandisk ultra class 10 32gb. try this setup. use minitool to reformat your card then set it the cluster size to 16kb.
for me so far so good. will test this in a couple of days.
So I am having a problem where my Sandisk 32GB MicroSD card is getting dismounted from the phone. It gives me an error message like "SD card has been removed. Please use the Safely Eject SD card option to prevent data loss" or something like that. Then, it finds the card and runs the media scan, which renders my card useless for that time period. The screen also turns on for a minute or so during this time. Then it stays mounted for maybe up until 5 minutes before starting over again.
This absolutely rapes my battery, taking it from a full charge to dead battery in less than two hours. I thought maybe the SD card was going bad even though it's fairly new, so I took it out and tried it on my old Motorola smartphone, and it works fine and never dismounts. So I thought perhaps it's something with my phone, so I tried an older 8GB micro SD, and it works fine without dismounting at all.
Some info. Phone is running stock 4.0.4 with root and unlocked bootloader. The 32GB SD card worked fine for maybe 3 months until this problem suddenly started. Any ideas?

It's behaving like mine did when the SD card croaked. 32GB SanDisk here as well...first SD card I've ever had die on me. I was able to get it to read, one time, on my TF101 to rescue my photos...now it won't read anywhere. I'm not sure what to tell you, except that I'd back that card up pronto, just in case...

Yeah, it was a somewhat common issue for a few of us about 4 months ago. I know blenkows and I both had it happening a lot. For me it eventually went away, not sure what the deal was, there.

This
My SD card wouldn't stop doing it. I just gave with it. Uploaded all my music to Google Play, put the 16 GB card that the phone came with in there. All is well now. Haven't had a problem with the card in there yet but I rarely use it now anyways. Basically just there for backups

Well thanks for the responses, I already backed up the data that was on there. I can't find my receipt for it...any idea if Sandisk is good about replaced defective cards?
I went through four RMA replacement 64gb class 10 SanDisk cards, ate the $90 loss and spent $80 on the Samsung equivalent. It's faster and I have had zero problems with it. However, I used SanDisk cards for nearly a decade before those without any problems.
The SanDisk hi capacity cards seem to not work well in the lgog. They worked fine in my card readers, just not the lgog slot.

I also had this problem with a 32gb sandisk. I RMA'd it and it happens less frequently for the new one. I'd say it happens once every few weeks now instead.
It's your card. I haven't experienced this at all n I'm using a no name class 10 32gb card. I was looking scandisk card but luckily I read the reviews n they where all negative

The phone will claim its checking the card & then claim the card has been removed.
Anyone else with a 64GB card have this issue? My Lower gig cards work fine.
My SanDisk 64 GB card works fine here. Hard reboot your phone.
Having same issue factory reset did nothing either. Even after this little ota
Backup card to PC. Format it, and see if that helps. If not, you may need a replacement.
My 64GB SanDisk is working fine. Just ordered a Samsung EVO 128GB, should be here tomorrow (oops, no later today) I think.
Like others said. Reformat it. I'd let the phone format it.
It happens sometimes. These cards easily get corrupted too because they often run a weak file system format like FAT or ExFAT. Sharing between PC and Phone is shaky too.
I like HTC phones because they support true USB Drive mounting which is less prone to issues IMHO and much faster too. MTP is awful.
Yea my sdcard is fubard, have to testdrive rebuild, it has lost all writing priveledges. This is all caused by my old piece of **** galaxy s4. ****ing thanks applesung

My Galaxy S5 corrupted my SD card and I noticed it when I tried to put it in the M8.
Yea it sucks. I think the internal write capabilities are ruined. Looks like I have to get in touch with SanDisk supposed to have a decent warranty
