Hi everyone, just wanted to confirm that 64GB MicroSDXC cards do work. I bought this one http://www.amazon.com/dp/B007WTAJTO/ref=pe_175190_21431760_M3T1_ST1_dp_1
At first it will not work, but you must format it with the phone and it will work well. Reports 59.6 GB

having tons of problems with mine; tried formatting in Windows (FAT32 with "guiformat.exe"), formatting in the device a few times...
Every time, when trying to copy stuff onto the card from my Windows machine, after a few GB the connection just drops...and then the card doesnt seem to work properly until re-format. Everything is *extremely* slow to respond, even to the point of screwing with explorer when I open "Computer" in Windows from the start menu...
Bad device? Bad card? PEBCAK?

Probably its a fake, do a google search about fake flash drives and memory cards and use the sugested program to test the card.
Warning, it will be slow.

believable- this is why I only buy Extreme Pro CF cards for my camera
alas...the Extreme Pro line stops at 16GB for the MicroSDXC line, (perhaps thats a hint at the difficulty of reliably making rad MicroSD cards?) and I'll be damned if I have an Android with less storage capacity than an iPhone.

Doubtful...sold by Amazon.com LLC. I don't buy eBay shiest unless I can't find it on amazon or somewhere that either accepts google wallet or is within driving/shouting distance. Still though, I took your advice and downloaded H2testw and will run the test tonight.
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.
Cheers

I just got a 64gb micro sdcard, when I first put it in my phone it was exfat formatted, so my phone couldn't read it. Once I formatted the card with the fat32formatter (found online), it worked great. Good luck.

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.
I've been using mine for about a year now, it's been working flawlessly. I had to format in my phone the initial time I first used it.

I decided to get a new larger microsd and it just came in.
Can I just mount this on one of my Linux boxes and copy everything over from the 16GB to 32GB one or is there something special which the Note does with it?
I have SD and USB adaptors so I can actually mount both devices at the same time.
I don't see why not

Well... the 16GB card flaked out upon insertion into SD adaptor and then into Linux box (write lock switch in place). Didn't look any better in USB adaptor on Windows. Says unformatted even when back in the phone.
So everything is fubared.
Not sure what component to throw away either.
Knew I should have manually copied the files while the card was still operational in the machine...
The key to backups is redundancy. If it's important you need more than a single backup.

The card was operating fine in the machine but I had seen some issues recording video and DragonBox+ didn't want to update itself. But it wouldn't update itself on either SD or internal, so I thought it was something else. So I ordered another card.
I actually found this card in the park in an adaptor last year and was surprised it even worked. I went to the trouble to save off the previous person's data in the hope of being able to return it to it's owner, but couldn't fine any identifying name address information.
The photos and video should all be synced to Google+ - I'm more annoyed about having to go and remove all the apps and re-install because you can't just refresh the install over the missing files on the SD.

I was amazed today to find that the new microsd seems to have all the files on it (11GB worth of files)! A friend thinks that the backup feature restored all the data overnight.
Oddly, ES File Explorer seems to indicate that the card only has 16GB, though. So I'll have to do some more digging tonight...
Ok, after buying a cheap and corrupted 64gb micro sd card, I went and spent the money on a 64gb sandisk card. It works just fine. Now, I am rooted and have synergy rom build 104 which is also running fine. I noticed before I flashed the rom that cwm wouldn't recognize my external sd card. I read up on that and found that cwm won't read cards formatted to exfat. So, I formatted the card to fat32 and remounted, transferred all my music back onto the card. Everything worked just fine until I plugged my phone into my computer. I was able to open and navigate through the files like normal, except when I went to open the music folder where all my mp3s were. I tried this on 2 different computers and on both the computer froze with the sand timer. The phone itself was fine, my music player(poweramp) was and is able to play the files with no issue. Also, when I unmounted the card and put it into a card reader and then connected the card reader to my computer and voila! Everything was fine, I was able to open the music folder and scan through the music files. I am not sure what the issue is. Can anyone shed some light as to whether this is a phone/rom issue, a micro sd card issue, an mp3 issue? Any ideas would be appreciated.
That sounds like a bad sd card. Have you ran a checkdisk on it?

If it's a SanDisk 64GB MicroSDXC UHS-1 then they have a replacement program where the older cards had issues in the S3/S4 devices. They sent me a free replacement and everything seems to be working. No Damaged card errors as of yet.

Hm, been searching around for this exact issue. Coworkers S4 with this exact SD card has been getting the removed unexpectedly error. Reformatted a few times, restarted phone, error comes back. It's in my Note 2 at the moment for troubleshooting, and so far so good, but this makes me move more toward an actual SD card issue in combination with the s4, and not the phone itself.

I called them and they are going to exchange it out for me. The weird thing is that I didn't get any damaged card error messages on the phone itself. It mounted it as soon as I popped it in. Even after formatting to fat32, it mounted right away with no issues. It only happened a couple days after I transferred all my music onto it. Is the free replacement they give you a newer card or newer model number?
+1 to the above. SanDisk told me they have a new version of the 64gig card with updated firmware, specifically for the S4. Package tracking shows mine is to be delivered on Monday.

They told me that too. My guess is it's due to the mass recall of the chips for the S3/S4. They said it's not present in Tablets so my 64GB in my tablet would be fine.
+1 problem with Sandisk 64Gb UH-1 card. Unexpected removal error. I am writing just for statistics. Just got my new Verizon S4 - and have problems...
FYI - I'm having a similar issue with a Samsung 64GD card. Got it to see the music for a while yesterday but after a reboot it can no longer see it.
Update, I received my new card and just popped it in. My phone automatically formatted it to exFAT. I'm not going to try changing it to FAT32, but is there any version or way I can get cwm to recognize the card in exFAT format? I tried TWRP, but when I flashed a rom it soft bricked the phone so I would like to stick with cwm.
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.

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.

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.

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.

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!

Glad you figured it out man. I didn't really do anything except to say keep trying. Lol. Good deal though.
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

Formatted ext sd via recovery...now I can't install, add or even format. I tried on pc and with twrp again by even using repair and changing file system. Anyone know how I can format this card? It's a 64 gb SanDisk. I can't find any solid solutions online. Thanks.

I have no idea of your hardware, but 64gb is where the switch from SD-HC changed to SD-HC (technically 32 can be either, but generally 32 are HC) and older hardware that didn't explicitly support XC wouldn't work... It either doesn't see it at all or sometimes it will work until you get to 32gb, then you can't write any more data.. I have older SD readers that so both.
But any phone or reader for the last 3-5 yrs handle XC, which has a theoretical 2tb limit, SanDisk has a 400gb microSD.. Insane.
Anyway that's all moot if it used to work in your phone and reader, but just doesn't anymore. Mostly if they're pre-formatted is exFat. If you formatted in TWRP I think it probably defaults to ext4, but TWRP can do a variety of formats.
I got to say though, if you can't reformat it again and TWRP that doesn't sound promising. Perhaps there is an Android app that will let you format with more control than the default tool (I have no idea since the last phone I had with SD was a Droid running GB)
Sorry I didn't really offer a solution, I have had problems with micro SD cards in general with generic brands... But I generally format them in the device I'm using them with and then I have a small USB thumb drive size thing that the micro SD card goes completely inside of and windows generally mounts whatever format it might be, provided drivers are installed.
Also sorry this is so long-winded I tend to do that when I'm voice dictating...
If you have more info that might be helpful drop a line. It doesn't take much to bugger up a microSD card though. Could be as simple as damage (static or physical) when removing it from the phone and putting it in the computer. But the proximity of time when formatted to not working makes that unlikely.
And I'm rambling again.
Cheers.

Well the Windows machine won't read ext4 without third-party software... But I don't see why that would keep you from formatting again. And if TWRP does the same thing, errors out, then I got think the card's had it.
If you're trying to use it in the phone you should leave it in ext4, but if you're trying to use it and windows you could try to format it exFat in TWRP.

I tried changing file system to a different type so that I could wipe it in twrp. But even after I do that, it still says it's ext4 on the pc

Nothing really.
I am curious though. Can you give me specs on the card brand/model/serial?
Also, I have had good results with UFS Explorer Recovery pulling data when nothing else will. I think there's a free trial, but you plobably have to pay for it to do anything other than verify it 'can' successfully recover, not sure, but if it is data that you need, it is good.
I only ask about the card because I found in the past I bought like three identical adata brand SD cards and one appeared to be DOA and I couldn't do anything with it and lo and behold adata had found a firmware thing that they could actually fix and they had a tool that did it.
If you want to go down a rabbit hole there is a sticky XDA thread https://forum.xda-developers.com/showthread.php?t=1355528&page=2 with various degrees of helpfulness. Its a little dated, but the ideas are sound for most of it.
Really i just googled "sd card bad after formatting twrp" and lost 2 hrs...
Let me know if you have any success, I realize this is either about data or just personal curiosity like mine... Because a probably sub $20 card is not worth this kind of investment... And if its a high end part, probably has lifetime warranty..

Did you request RMA?
https://kb.sandisk.com
I'm not sure if they are lifetime warranty or not, i have a couple ultra plus cards from Costco that were lifetime warranty.
Now on the less ethical side, if it's a current model, plckup a new one then swap/return. But obviously thats evil.

I would swap....but my data is on it. Lol. I can't delete ANYTHING on the card. Can't format, or right click a file and chose delete. It somehow got from ntfs to ext4
