[Q] MicroSD card issue - Galaxy S II Q&A, Help & Troubleshooting

Hello there,
I just bought a 32GB Class 10 Samsung MicroSD card.
After inserting it, I made sure the phone sees it, and the computer sees it.
So I started transfering files to it...
Every time I try to transfer files to it, the cards sort of unmount, the computer stops seeing the External/Internal storage drivers info (0/0 KB and no files).
I realized I might be needing to format it, so I went to recovery and formatted the external card. Still no good...
If I don't try to transfer files, the internal sd card still works fine.
Am I formatting it wrong? or some other issue? Did I buy a faulty card?
Thanks!
P.S. Some info incase needed:
Using Galaxy S2 obviously, Resurrection Remix ICS 4.04
My PC is running XP SP3

Added some pictures to demonstrate what I mean.

If unsure about the quality of your SD card google for h2testw. It is a Windows test software you can use to test your SD card.

Tried formatting it... still no good.
And h2test tries to copy a file repeatedly and after some time it also gets stuck like I do manually...

I was running into the exact same issue as you with an SD card awhile back. Tried many, if not all of the suggestions listed here. Sometimes, the cards just die on you, especially at the most inopportune times...

Open CMD
Type format [letter_of_external_card]: /x
ex.
format E: /x
and wait.
Then format again (through Windows Explorer) with this settings:
FAT32
default allocation size
fast formatting checked
and share the results.

Failure of h2test is normally due to defective hardware.
For SD cards I do not really know but when it comes to USB sticks there are many around that are just cheap crap. You could for instance buy a 8GB stick that will happily accept 8GB of data but only store 4-6GB!. This is where h2test comes into play: it will not only write but also read and therefore check if the data written was really stored in the flash.

Class 10? That card might be just too fast for your hardware.
I'm using Sandisk 32GB Class 4 and never had any problems.
I have tried some Class 6 and Class 8 cards with very various results.
Only class 8 card I found correctly working in my device was Memorex, but it was only 4GB.
So I gave up on fast cards...

its fake or corrupt,did you buy the samsung off a retailer , you always test flash with h2testw before you use it, speed is not the issue,i got a class 10 32gb i had many 16,256,4gb fakes, only 3.7 gb usable droped down to 1kb write then windows couldnt read the storage so you reformat again.

32Gb Class 4 microSDHC - Phone unstable! Please help!

Hi all, I bought yesterday 32Gb Kingston Class 4 microSDHC card. Now my phone is very unstable with this memory. I mean, sometimes it can't mount it, sometimes it shows its empty, formatting almost hangs phone, some apps hang phone (apps on sd). Looks like the phone doesn't want to eat this big memory too well.
I already tried soft reset, and dalvik cache deleting. Didn't help.
microSD is formatted into Fat32 and 32Kb clusters in windows with HP Formatting tool.
If I try to reformat with phone, nothing seems to happen....
It can work perfectly for a 20min, but if I try to turn many apps on and off, it will reboot. After what it doesn't see apps on SD card. wtf? But after complete reboot, it'll work again for a some time.
I have 2.2 Android from elelinux.
If I use my old 2Gb card, everything works just great.
Any ideas?
P.S
What does this recovery mode SD card formatting? Maybe I should try this one?
I have ClockworkMod Recovery 2.5.0.7. There are some interesting options like..
What ARE these?
1. Format Cache
2. Format SD card
3. Format sd-ext
4. Wipe Cache Partition
P.P.S LOL I can't turn off phone. It is rebooting always. Wtf?

According to the HTC website, our Hero's should support 32GB.
But that's as far as my knowledge on your issue goes. Just ordered a 32GB Class 4 SanDisk card myself, so when its delivered (hopefully Friday) I'll let you know how it performs.
Just an update for you, mine came in the post yesterday and it seems to work fine with my phone. Loaded it with 20gb of music and it runs fine.
Yep should run fine with 32gb sd cart
i'm having many of the same issues with my 32gb. had a 16gb before, and all was well.
now the phone randomly goes back to charge only when i have it plugged into PC as disk drive. i'm having trouble making backups in recovery too as it says its randomly unreadable in the middle of backing up. also, and seemingly most frustrating, is it is refusing to actually transfer files from PC to SD. i will plug in as disk drive and move all files without issue. however, when i eject disk drive and switch back to charge only mode (or simply unplug), none of the files have actually been moved to my device. they are simply missing entirely when i open any file manager.
i've tried everything. formatting on device, formatting through W7 (quick and full), and formatting through the official sdcard.org tool. nothing helps.
Try this
If u have a linux PC, u will know about gparted, I guess.
Do this: boot to ur favourite linux distro. plug the sd card to ur pc using a card reader. open gparted. click tools and then click new partition table. it will wipe everything from the card.
once done, just setup the partitions as u want for fat, ext or whatever. i was having a htc tattoo troubling me with a 16GB card but now its okay.

SD card stopped being recognized abruptly

Hi
My Xperia Z2 tablet stopped recognizing the SD card. It was perfect before turning it off. When I check "storage" under settings it says mount SD card. Nothing happens when I try to mount it. Is this an SD card issue or a tablet issue?
Thanks

What is your SDCard?
Have you tried to reformat it on your comp then re put it in your phone?

My card is Samsung 64 GB Class 10, bought from ebay. I had a movie on the card which I was watching on the tablet last night. This morning however, the tablet did nor recognise the card. All it says under "storage" is mount card, and i tried mounting the card but nothing happens. The card was not formatted on a computer, but erased by the tablet before being used.
The reason I mentioned ebay is because, according to google, many cards on ebay are fake. I'm only hoping it's the card not the tablet.
Thanx
What File Manager are you using? This happened 2 times on my Xperia Z Ultra and 2 HC 10 32 GB cards were destroyed...but it happened only by using Total Commander, since that time I do not work with him anymore and everything is fine...

I did not install a file manager. The tablet came with File commander, and that's the one I use.
There are a lot of fake/faulty sd cards on eBay, try it in a different device.
Same SD, same problem

My card is exactly the same (I think) Samsung miniSDXC 64GB. Bought from a normal retailer. Similar problem to yours (I think)
I have not been able to find a solution.
The SD worked fine for a couple months. I notice there is no click upont pressing the card in (as the Sony manual describes) but it seems to sit a fair way in. Sometimes when viewed in Settings the card is visible but never when the phone is plugged into a USB port of the computer. Mostly it shows instantaneously when you push it in and then dissappears as quickly and the request to mount a card shows.
On one of the few times it stayed visible (not with the USB cable in) it showed about 12GB used. It seems to have been coming on and off intermitently during use. Accordingly, some photographs end up going to it and then not being accessible and some, or most, just end up in the main phone memory. This is assumed as a number of photographs taken are not showing. I have sent them from the phone main memory via dropbox as the computer can access none on the phone at all...perhaps because I have pathed them to the SD.
Will get and try another SD card but one possibilty is that this may be a problem with the SD card housing in the telephone.

SD Card Removed Unexpectently

I have rooted my z2 and the sd card is constantly mounting then unmounting. This is getting really annoying as when trying to watch movies or listen to music it just stops halfway through because it removes the card. has anyone else had this issue? Also i am unable to download the latest android update all it says is unable to verify.
Well if you unlocked your bootloader to root, then you won't be able to update your device through official ways anymore.
I have no idea about your SD card, try backing up its data on your pc and then reformat the card?
Yeah probably have to wait untill some custom roms come out
reformated the card exfat, however everytime trying to copy to the z2 it will copy for a while then it will disconnect meaning i have to start all over again. I dont think i have came across a tablet that is so bad at handling an sd card truly awfull. I hate to think how bad shooting video will be with the card continously mounting then unmounting. Ans no its not an issue with the card because it works perfectly in my pc and galaxy note 10.1
Anyone ??

What if you reformat as fat32 with 4096 bytes cluster size, instead of exfat ?
Have you tried running an error check on the card ?

not possible to format fat32 in windows no more by default. And the issue is any videos etc on the card will be limited to 4gb file size. The Z2
natively uses exfat so why would it keep disconnecting? when i pop the card into my galaxy note 10.1 it doesnt do it so it is clearly an issue with the tablet, but will give it a try
with fat 32

Then I suppose your tablet has a faulty card reader unit. I'm sure you can get it replaced or repaired without any hassle.
I am on my second, stock romantic same issue on both unless it's in its case
tried fat32 and the same thing happens what an utter load of rubbish cant even handle a 64gig card. btw this i my second z2 same thng happened on the first before and after root. Thought i would try sony as never tried their tablet devices before and was impressed by the specs on paper, what a major mistake the worst tablet ive ever used. Im gonna return it and stick with samsung like i always have and ugrade to the new note 2014 edition. Sony Fail!
Well if it's the second one in a row with this issues, I think there must be something you're doing wrong? Or maybe your SD card specs just aren't supported? What are the full specs of your SD card? And is it one of those extreme high-speed cards for (video) cameras? And aside from reformatting it on a pc, did you ever try reformatting it on the tablet itself? This is an issue I've not read of about this tablet before so it kind of puzzles me that you already had it replaced once and immediately have the same issue again.
its a sandisk ultra micro sd card i have formated both on the pc and the tab. Also i formated it as fat32 but after a while being in the tablet it seems to convert it to exfat again. i have also tried different cluster sizes. I have tested this card in my samsung s3 samsung galaxy note 10.1 pc my laptop and have no problems at all so im at a loss

Only idea I have left is for you to try other micro sd cards and see if they cause the same issue.
I think it might be to to with the number of files the tab can handle if i have nothing on the card it doesnt seem to do it but the more files are added it starts to keep unmounting the card and constant rescanning. i have about 3000 mp3s on the card. Its not like its cheap memory its a sandisk 64gb class 10.

Micro SD problems in HTC One (M8)

I have a 64gb Sandisk Ultra SDXC card formatted in exFAT. I had been using the card in my NOTE 2 with no issues. I normally keep all of my movies, music, emulators, and ROMs on it so I can keep space free on my phone. This morning I got my phone setup the way that I wanted it and I decided to install the SD card into the new phone. Everything seemed to go okay, I got a message telling me that it was preparing the card, but after the message disappeared, the SD card was not recognized. There were no error messages regarding the card, it simply did not show any additional storage on the phone and all options regarding the card with exception to "Mount SD Card" and "Format SD Card" were not accessible.
I took ejected the card and formatted it to NTFS to see if that would make a difference and when I reinserted it into the (M8), it recognized it as a blank SD card that was not in the proper format. It prompted me to format the card while still installed in the device, which it did without error. After the format was complete I received the same "Preparing SD Card" message that I received before, but after the message disappeared, the card still didn't show up as additional storage.
Through a root browser I have the option to enter extSD, but nothing I put on the card is there. I then took the card back out, installed it into my Note 2 and it worked with no problems at all. Finally I ejected the card, reinstalled it in the (M8) again, it gives me the same prompt as before, but after the message disappears the additional storage does not show up and all options with exception to "Mount SD Card" and "Format SD Card" are inaccessible once again.
I have tried the fix found here: http://forum.xda-developers.com/showthread.php?t=2700310 to no avail.
Does anyone have any ideas why this might be happening and is there any way that I can solve the problem?

If you have a USB card reader, try formatting the card as FAT32 with your computer.
I believe most cards come pre-formatted as FAT32 by default. I've always just put the cards in my Android devices without any formatting, and they work just fine.
Not sure why the device's default format didn't work, but possibly formatting on a computer will get it working.
It's possible that SD may be dying.
I had a 32gb card that a friend left with me to fill with movies/etc, but since I wasnt going to see them for a while, I decided to use it with my old LGOG. Not 3 days later, I get what you described, and now the card isnt even seen by Windows.
Even with formatting the card, it would work again for a few minutes, but as soon as I tried copying more than ~3 gigs, the card would go corrupt again.
SD cards dont last forever yo.

I just tried it out a few minutes ago. I don't know why, but it's working perfectly fine in Windows, a Note 2, S3, and an S5. I have no idea what's going on, but no matter what I try, nothing makes it work on this phone.

I was able to get the card formatted form exFAT to FAT32 and it looked like it was going to work, same with NTFS. I inserted it into the phone, waited for it to prepare the card and this time I got a message telling me that the SD Card was damaged, but I could format it in the phone. I followed the instructions, just as I had before, it went through it's thing, got to the part where it attempted to mount the card, appeared as though it was going to mount, and then nothing, just like with everything else. I have no idea what's going on.
I ran some tools on it and the card appears to be in good condition, so I have no idea what to do. I don't know if it's the phone, or if it is the card. I'm thinking about buying a 128gb card, but I'm afraid if I do, I'm going to find myself in the exact same position that I'm in now and out a lot of money to boot.
I'm loosing my mind with this thing.
Surely you must know someone that has a MicroSD card you can try. Trying another would pretty much eliminate the card as being the issue (and possibly the card tray or similar component on the phone). I have at least 2 "spare" MicroSD cards laying around.
I had a similar problem few weeks ago and I did format my 64gb card with GUIFORMAT on my win 7 PC and since then no more problem. Here is the link: http://www.realmodscene.com/index.php?/topic/323-gui-format-fat32-drive-formatter/
Thank you. I'll give it a shot right now.

You, sir, just won all my Internets. I don't know what it was about that app, but it worked like a champ the first time around. I don't get it either. I had used so many tools to get it to FAT32, but this one did the trick. I formatted the card, inserted it...was totally waiting for it to not work, and I noticed "Unmount SD Card". I read it and thought "hmmm, that's not right", lol. Then it dawned on me that it worked. Copying folders over to it now. Thanks so much, bud. I really owe you one.

Nice. I've heard that the native Windows formatting tool is not the best (although its always worked fine for me), so this might be one of those instances.

[Q] μ files on my sd card. is GS3 frying sd card?

First of all, im using a 4.1.2 stock and my device is rooted
So i had an Sandisk 64 GB class 10 for some time which one day became a "read - only" card...
So afterwards i bought a Samsung 32 GB class 10 which I found out also had problems because i could put about 10GB of files and everything more that 10 GB turned into wierd folders that their name starts with "μ" and there where no actual content inside and i couldn't delete them.
So now i'm at my third try, again with a Samsung 32 GB class 10 which also has the same problem, only now i can write on it about 20 GB of data before files start to get curropted.
Just want to say i bought all 3 SD card from Ebay, and though i guess they might be fake (tons of bad luck), after searching the web I found out there are many GS3 users with the same problem...
So i just want to put an end for this question..
Is GS3 frying SD cards? is there something i can do to stop it from destroying SD cards? can i fix somehow the SD cards?
thanks alot!
Hi! when you are asking a question you should include details such as operating system(4.1.2 , 4.3, 4.4, stock, rooted and so on) and file system. I noticed while searching google that the majority of "s3 fried sd cards" so to speak are sandisk and in your case it seams that there is no such "limitation". Maybe if you give more details someone might be able to help.

not sure. I formated it with my GS3 and the computer won't recognize it without reformating it.
Worst case scenario is your phone somehow corrupted the sd card and that is that. I had a similar problem with my usb flash drive which i used on-the-go and unmounted it before removing it but when it happened i didn't make a backup(as always) and got stuck with a nice keychain. If you have the possibility to format it under windows with a card reader and choose fat32 at least you have a working sd card, otherwise use your warranty for the sd card(if you have one) and always BACKUP.

but do you think that my device is malfunctuning in a way that will keep frying my SD cards..?
well since this is the second sd card i personally send it on warranty(as hard as it may be without the phone) because it seems that something is not right with the contacts of the card reader circuit board. I read somewhere that on some phones the card reader slot had some contacts partially detached and so the sd card kept getting corrupted. Search a bit on google about this issue and take into consideration using your phone's warranty. Best of luck!
That is a bit strange. Unless you're used to remove the sd card with the phone accesing to it (no safe removing) or removing the battery while the phone is running, that's absolutely not normal.
I have my 32GB sd since 2010 and I never had any problem. I formatted it this year because it had tons of useless data and I liked to have it clean.
Of course it's not from Ebay! That is bulls**t and use to fail suddenly.
