Anyone use one ?
I've got a Sandisk Class 10 "Ultra Android" one but it's been a bit .. flaky .. i suppose. I use winamp on my S2 and it occasionally hangs it to the point I need to reboot.
I'm wondering if it's just down to the number of tracks i've got on it - 8,500. Even though it's a class 10, I'm just wondering if selecting "Shuffle" when I start using it, it has a bit of a brain fart when faced with shuffling that many songs.
On the whole, when it's actually playing, it plays fine, but just wondering if anyone else has one and has had any issues ?
From what I have seen based on reviews of those cards just don't work well. I work in a store that sells them and I won't buy, but that's partially because I can't stand the thought of corrupting more than 16 GBs at one time.

I think the SanDisk cards are faulty so many people have problems.
I use a Lexar and it's been great

I've always thought Sandisk was one of the more reliable brands. Interesting.
This says that my card is compatible with the S2
http://www.mobilefun.co.uk/sandisk-mobile-ultra-microsdxc-memory-card-64gb-p32149.htm#compatibility
but then i've also read that the S2 can only cope with no more than 32gb.
I'm using SanDisk ultra class 10 32gb and have no problems whatsoever.

Same 32gb with no issues at all

I was also using a Sandisk 32gb Class 10 as well before this - I still have it.
I did remove the primary partition on this 64gb card and re-create it as a FAT32 partition so it would work.
I also flashed a Jellybean ROM to see if the handling would be better and to be honest, I think ICS has actually been better overall at handling the larger capacity.
I have a 32GB SanDisk Class 2 MicroSD. Even though it is super slow, it has been really reliable. I have experienced zero crashes or hangups.
well the card now seems to have completely given up on me.
i decided to move back to ICS so prepared everything as I normally do. I repeated the procedure of removing the primary partition and re-creating a formatted FAT32 partition which completed successfully. i tried formatting it in CWM and it failed to mount. I flashed Rootbox ICS 1.8 which flashed fine. After booting, I chose "Erase SD Card" which ran through and seemed to complete without any errors but when i plugged the USB in, the card fails to mount again.
Rebooted and found that when i mount USB storage in CWM, the SD Card is properly recognised and checks out as properly formatted to FAT32 but the phone just point blank refuses to mount it under any circumstances.
Also, I select the USB Storage to copy files, it mounts the phone just fine but no SD Card. When i turn USB Storage off, it tells me i have a damaged SD Card and do I want to re-format - so I do. It completes without any obvious errors but then still won't mount ..
Just hugely frustrated at the moment ..
Is there a point where i should just give up ?
The card formats absolutely fine and checks out when formatted through the PC but the phone just doesn't want to know, under ANY circumstances ..
ok i give up. i just don't know or understand what's happened. i've deleted and re-created the partition a dozen times with a dozen different parameters. each time it completes successfully and each time the card shows up in windows as correctly formatted but the phone refuses to recognise it at all.
i've tried the format32 program, paragon partition manager and minitool partition manager and all of them successfully format the card without error and each time the phone DOES NOT SEE IT.
so i give up. i'll put my 32gb one back in and decide what i want to do - i imagine i won't be able to return the card because it formats correctly and works correctly in windows so i guess i can always try it on ebay
now you know when you do something completely random at the end of a few hours of puzzling over something ?
i literally just randomly selected "partition sd card" in CWM recovery, selected the maximum values on each and it ran ok and completed. rebooted and went to "storage" and .. IT SAW THE CARD ..
so i rebooted back to CWM and selected "format external storage" and it's done it .. formatted it without an issue .. i'm a bit stunned
it's only showing up as 59gb free mind, but i think i can cope with that .. and i think that's about average for the free space on any storage as well .. i can cope

59GB is the right amout of storage.
Harddrive and storage manufacturers calculate hard drive sizes using Base 10, where 1000 bytes is one kilobyte. Computers, however, do everything in binary, which is base 2, where it takes 1024 bytes to store a kilobyte of data. In addition, the computer’s OS uses part of the drive for a directory to keep track of the actual data. The result is, the usable capacity of a hard drive is typically 90 to 93% of the advertised capacity

Yeah, I did suspect that. I'm just relieved it's working - it wasn't cheap and I'd also bought it from China, so it would have been an immense amount of hassle to return it if i had to.
is it possible to swap mount points, make external sdcard the main mount point? as i have lots of large data i.e games i would like to install straight to sdcard....im on stock rom 4.0.4.........it was and is possible on CM9 rom but i like stock better, is the a way to edit vold.fstab in /system/etc to make this possible or is there another solution? thanks

The games that have large amounts of data downloaded after installing the game, such as NFS Hot Pursuit, puts the extra 600MBs of data in the 12GB internal storage.
so is it not possible then?

2. Wireless connection gets dissconeccted automaticlly
3. The whole Android software get crashed and the screen goes into black, then this can't be solved if I didn't remove battary and reinsert it.
I Tried to check the SD card for bad sectors and problems but there were nothing.
Any Solution?

If you remove the card the problems persist?

It happen to once with my cheap 4gb card when i paired with nokia n82.. Till now i don't know why the phone keep refusing to recognize the card. The irony is, the "rejected card" works normally on my current phone "sk17". it left me scratching my head.
If you can return it, return it. If its not worth it, just get a new one. Basically, you have done everything on you end, so its definitely the card's fault.

Check for SD card class,its written on SD card.If its less than Class 6 then you should buy SD card with class 6 or higher.
Second you should not place large files like multiple blueray pictures or multiple songs in single folder.And last you can speed up SD Card read,write speed by using SD booster of Root tool box pro app to make your SD card faster.
I thing class is not so important. I now using few year old 16 gb card class 2 without any problem
Sent from my ST15i using XDA
Weird but I have no reason not to believe you.At least you know that the problem is the card,so either return it and get a new one or buy a 16Gb instead.They re already pretty cheap! Opt for a class 6+!

Why should I avoid putting multiple songs in one folder? I have put like that and my sd works fine eh??
and the other thing if you had apps in the other sd which was 2gb and u put the 8gb one without transferring them to the 8gb card the apps should not work. Android system failure sould be a problem of memory management. Check whether you had filled ur card.
and yea I think the best solution for u if u have tried every thing, return the card
Hi guys
I know about the SanDisk Micro-SD card problem with Samsung Galaxy S3's and I happen to be one of the victims.
My SanDisk Micro-SD 32gb Ultra has had problems in the past. It sometimes says blank sd card but it eventually works again. At one point it said sd card damaged but the card still worked. Up until yesterday it hasn't stopped working for a while but now my phone says blank sd card. I tried putting it into a windows computer but it cannot be detected. When using a usb adapter it just shows a device in drive "?:" and can't do anything with it and when using a micro sd to sd card reader it doesn't show at all. In Mac the micro sd to sd card reader is detectable and shows the size of 32.1 MB and is called "Apple SDXC Reader Media". The micro sd card itself is not detectable it seems. I have tried many device recovery software but none of them work. They all seem to just be scanning the card reader and not the micro sd itself.
Does anyone know how I can recover the Micro-SD card?
It is quite important because I have my school laptop data backed up on it (which was just handed in for a system upgrade and being wiped) and also my phone pictures, videos and other stuff.
Any help will be greatly appreciated

It may be recoverable by a specialist company, But i believe the going rate is approx £900. My first step would be to try sticking it in the freezer for at least 8 hours (but as long as you can manage the longer the better) then try it in your phone, if this works back up all the data and RMA the card to SanDisk. Let this be a lesson to us all that all data on our cards should be backed up regularly, I understand you werent expecting the card to fail but had you lost your phone the result would have been the same.
I doubt you will be able to recovery the data, formatting the card with the sd formatting tool might make the card useable again but I doubt it. When I've had cards corrupt more than once it is best to throw them away and get a different make.
You can try looking for a specialist data recovery expert, locally or on the web - if the data is very valuable to you.

First of all I don't have £900 to throw around, besides the fact it totally isn't worth £900 to get it fixed.
Second, before I start chucking my SD card in the freezer what exactly does freezing it do and how will it help it? You sure it won't just destroy it for good? I can leave it in the freezer for as long as needed as I can't exactly use the card in the mean time.
Thanks for the reply though
Hope I can get it to work
Freezing is a method that may give a brief recovery on some hard disc failures .
Note hard disc never heard of freezing ram or why it could work .

Not a lot.Contact retailer, or SanDisk direct for a replacement card and chalk it down to experience.
This is a known issue with sandisk at the moment. They are replacing cards when they die.
As for data, please look into foldersync for future. Sync data to cloud or computer

Ok then I'll just have to get it replaced.
A thought just occurred to me though.
Before I had my school laptop backed up on my micro-sd card I had it backed up on a usb. Because it was only an 8gb usb I transfered it to my micro sd because it took up too much space. I've heard of software that can recover deleted files from devices. Would it be possible to recover the deleted backup on my usb? The backup in total would have been about 1 - 2gb. If so, what free program could I use to recover it?
Thanks in advance
Possibly. As an IT support engineer, I don't want to get your hopes up though.
Things like NTFS get back may work but most if them are not free.
I took Handy recovery 1 (free version) from a bootable cd tool once, you could try that and may recover a small amount of data but its always safest to assume it gone.
The more you use the usb device, the less chance you have of recovery

Think they would have something to fix the card or recover the data?
It depends on the state.
The media has a File System. This could be FAT32, NTFS, exFAT etc. Essentially (without going technical) imagine these file systems as a database table. When you add a file to the media, an entry is written to the table to identify the exact location of the file on the media. That way, when an operating system views the card and the user accesses a file, the table tells the OS where to look for the file.
Typically with these file systems, when you delete the file, the file remains. Only the Table entry is removed. The OS can no longer locate the file. the OS is shown the free space as per what the table says - not what is really the truth.
So once a file is deleted, 3rd party applications can scan the media and find the files (without using the table).
Of course there is a problem in that any space that the table shows as unallocated (you deleted the file), new files will overwrite the old files. That is when the data becomes unrecoverable.
So yes, it's possible that even if the formatted filesystem is damaged, the data on the media can be recovered. But if you added new files since, then the chances are the unreferenced data has been actually overwritten. In this case, it is gone.

What file system are you taking about here? The damaged file system (micro-sd card) can't have new files added to it as it is inaccessible. It also has not been formatted since the problem. The usb with the deleted files is not damaged and not formatted but I have put new files on it since. Sounds like you're combining the two different devices. Sorry if this is a bit confusing.

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.

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.

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.
It's a SanDisk Ultra 64 GB MicroSDXC Class 10 UHS-1 Memory Card with Adapter (SDSDQU-064G-AFFP-A)
At Amazon.

Glad you figured it out man. I didn't really do anything except to say keep trying. Lol. Good deal though.
When I use a 128 micro sd as internal storage there is extreme lag in evry app, which is not present with a 32 Gb micro sd. I think the internal storage might be using fat 32? I was promised lots of storage :crying:
This is very important to me and probably others

Getting error messages when trying to format it with anything

and another error code that I lost hope this can help to find a solution :fingers-crossed:
Wait I finaly found a solution
Step One: Format SD to exfat.
Step Two: Set SD as Portable in Android
Step Three: Format SD as Internal in Android.
Step Four: THIS IS IMPORTANT. The process will eventually freeze and timeout. Do not cancel it. Let it timeout. When it does do not fret. Shutdown the phone by holding power and tapping Power Off. It will take a while to fully shut down. The time it takes for the process to freeze and the time it takes the phone to shut down seems to depend on the size of the SD Card. My 128GB card took about 6 minutes to timeout and about 12 minutes to shut down. DO NOT FORCE SHUTDOWN*. Let the phone shut down on its own. When it does, boot the phone back up and the SD will be set to Adopted Internal Storage.

I scanned it with a checker and it it returned as good, so I think there is no corruption and I suspect android as the primary suspect
The same happened to me with a SanDisk 64 gb Class 10 card. Turns out I can't find a way to format my card back to normal, not even with a pc. Not even low level format or any commercial format tool.
Seems there is a bad batch of SanDisk cards or so I read online. Will return mine just in case.

The only way I got it to work w/o xposed mods is to use fat32format windows program to format my 128gb card as fat32.

what program did you use
It's called exactly that, fat32format. I don't recall where I got the program exactly but download it from a reputable site like like cnet's download.com site or softsonic. Do know that since it's fat32, it will not support any single files above 2gb so no 1080p rips and the like.
I agree with the others sounds like you have a bad card that is on its way out... I had a early sandisk 64gb that one day just vanished nothing could be done to bring it back either... I avoid sandisk cards for now I want wd to have plenty of time to wash the crappy cards out of the market.
Fat32's file size limitation is 4gb!
If the SD card is inside the device better pick exFat.
there's no actual android app that has single files that big so you can use fat32 just fine, just won't be able to save big files on it like ripped movies

exFAT has problems with this tablet. FAT32 works flawlessly.
exFat makes problems. Good to know. Well, Microsoft..
By the way, NTFS works too! Having one in my Shield right now.
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.

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..

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.
