Hi,
I received my new Touch pro and it worked fine for a day, i noticed that it would stop reading the card. i would press the back and the thing would read again. take the card out and put it back in and it would work. then it stopped working all together. No matter what i card i put in it does not read at all.
I put the card into my PC to test and it wont read, i put in another card and it reads fine in the PC but not in the phone..
does anyone know of any utilities that i could use to repair this card.. maybe the FAT table got screwed up.
Eazy
if your PC read the card, so i think not the card is damaged
i think your diamond pro isnt work well...
no..
I have 2 cards.. a 8 gig and a 1 gig.
the 8 gig worked fine until my diamond pro broke it. it will not read in the phone or the PC. my 1 gig wont read in the phone but works fine in the pc. the card reader in the phone is now dead and the 8 gig is now dead. when i put the 8 gig in the pc it will come up with a drive letter but with a 0 file size and when i click on the drive it tells me to insert disk.
so does anyone know of a program to repair the SDHC?
firstly, thats a Micro SD card, not a SIM card.
Secondly, please could you give more details on make/how old/type of the SD cards trying to be used.
Chances are it was still trying to write when u pulled it out, so it needs formatting.
if you format it make sure it is the right format!

I figured that you noticed after my second post that the subject was wrong..
anyway.. its a 8gig SanDisk about 8 months old. also there was no chance that it was trying to write when i pulled it out. if you look at my first post you will see that the card reader on the phone is damaged and im looking for some type of program to repair the Micro SDHC card...
I am not going to format the card.. I need the information off the card and Ontrack wants 100 to look at the card and 400 to recover the information. This card worked fine with my other pone until i got the diamond with the bad SD card reader.
There's no such thing as a Diamond Pro; only a Diamond or a Pro. As you're talking about removable memory cards I assume you mean the Pro, in which case you're in the wrong forum and you're likely to get more constructive feedback here.
You guys are killing me.. What does that have to do with the fact that I have a bad SDHC card and want to know if there is any application out there that could help me out. If nobody has one to help me then I guess that’s just the case. You guys really get tied up on minute detail rather than the situation on hand. I will edit the subject again, and maybe it will get moved over to the Raphael area..
Thanks for your responses..

Might be a daft question but, have you tried chkdsk?
If that doesn't work how about a/ looking at the card with parted (or similar) in Linux or b/ finding a hex editor that will read the disk 'surface' directly.

i will try my linux box in a few minutes..
let me clarify..
i would go to file explorer and it would see the card.. i would try to go to a directory and ht would not see the card and only show my device. i would take the cover off and press on the back, turn the phone over and it would see the storage card again..
so technically if it had a loose connection and while browsing the directories it lost connectivity that could have possibly simulated the removing the card while it was writing issue.
Eh..
Thanks guys.. the linux box could not mount the card.. Ill send it out for recovery.. :-(
Try following the links from this Artemis thread for hints to recover any salvageable data.
I guessed, along with others, early on in this saga that writeback cacheing could be the culprit.
The 'fix' that eventually solved the problem tends to suggest that hardware, (bad contacts etc) wasn't the problem IMO
The end result is the same though, the FAT or mbr gets messed up.
How about fdisk/mbr on your SD (research first though please).

Funny, I was just searching Google for a fix or repair software for my SDCH card that my Fuze broke and ended up here (my favorite website). I guess is a phone realted issue?
i know this isnt the first of this post. people dont use search anymore. but i had bought an 8gb sandisk card for my fuze when i bought the thing. shortly after the card went all stupid on my like everyone else. i was told by att it wasnt an issue with the phone, it was the sd cards. att replaced it for free, quick and easy, no questions asked. see if you can get it changed out for you where you bought it.
Hi!
A few days ago I bought a Takems 16gb class 6 microsdhc and it worked, but today i put the card in a galaxy s...when a put back in my desire the card was working but the phone can1t write... i tried to format but i can't it, because the card is write-protected...sd adapter has a lock/unlock switch but it can't help...
how can i remove the write protection?
there may be a password on the card
or encryption
hmm...i tried it in my friend's galaxy s, but didn't work...
i can't foramat the card...low level format didn't work....
i don't have any idea..
I have the same problem...
HELP please!!!
but mine is Sandisk 16GB class2, used for about 1 year without problem.....but now......cant write, cant delete, cant format (even low level)

:S
There is only one solution... destroy it with a hammer
you can buy a new card or give it back and request a new if it has guarantee
return to seller or use linux and gparted or sdformatter from http://www.sdcard.org/consumers/formatter_3/SDFormatterv3.0.zip
to format the card and try to bring it back to life
I'm not sure why in this situation people insist in saying "format the card" with one piece of software or another as this simply will not work.
I have an 8gb USB stick that has done the exact same thing and no software you try and use will format it as they all report it as write protected.
Gparted, hp utility, sd format, a long list of other usb formatting tools, partition magic the list goes on none of them work.
Even a low level format at linux command prompt will not work as it gets mounted read only so it just errors.
This is an error where the hardware is mistakenly interpreted as write protected, very often caused by a write interrupt leaving corrupted data behind.
After about 2 weeks of trying every solution on google I have come to the conclusion that the stick is no good you can read what is on it already but that's it.
So my advice is stop banging your head against the wall and just get a new stick, format it and copy over what is on the old one

nothing will work..trust me.. get a new one!
chague another SD
i got a replacement xoom and when i tried putting in a memory card in it, the memory card would get stuck. i managed to get it in but now it gets super hot when its plugged in the xoom. any reasons why?
I would remove it very carefully but it sounds like something is wrong. One of the metal prongs/leads/whatever on the card may have gotten skewed and could be causing mischief.
actually i think its the memory card cuz i put another one in and that one works and doesnt get hot. by the way the memory card i tried first i had it in my evo and then a few days back i had a notification saying blank SD card, do you think thats the problem?

it sounds like your memory card has either gone corrupt or is trying to. I would suggest backing up your data on that card. I say this because the memory card that I have for my Droid 2 started doing that as well as *uninstalling* all my apps that I placed on the SD card (saying that the files were never there and such, but when placed on my Windows 7 computer, it would be there,) and then would bog my phone down while trying to read the card. I tested to make sure it was not the phone itself (which it would have sucked!) and the same thing happened in two other android phones, proving it was the SD CARD because other (as well as newer too) SDCARDS I had laying around and none of them had this trouble. Even a SD Card testing APP on the market said "Uh yeah... it's dying!"
Because Android is on a linux flavor, it likes to KNOW EVERYTHING on the card or it just does not care for it and then treats it like a blank card. I would suggest that if you want to try and salvage the card, do a quick format AND I WANT TO MAKE THIS CLEAR: to the same file allocation system (aka Fat16 to fat 16, Fat 32 to fat 32, NTFS to NTFS. DO NOT CHANGE THIS unless you know what you are doing!) Also note DO NOT do a full format because this will write to every sector of the SD Card, and that is really really bad for the SD card as well as any flash memory...
A quick format just goes over the file allocation tables (a table that stores information for where the information is located on the card) and then try it again. If problem persists, call manufacturer of the card or where you got the card originally (evo = call htc, droid 2 = call motorola, ETC) and see if it is still under warranty.
Good Luck and I hope I helped you out some
I haven't searched but saying that I've never seen anything like this on Desire or Sensation threads before.
I went to copy something over to the phone (using Windoze Explorer) and when I looked at the contents. I saw the attached. The phone, when I use Root Explorer, and PC agree :-((
For reference I've used Linux, PC (Explorer) and ADB 100% to copy files over successfully before, so no posts about using one or not using one.
All the Filenames etc. have been completely screwed up. Looks like they've been converted to DOS 8.3 format.
I have never ever seen this before. I think I must have run something on the PC when the phone was USB connected. It's about the only thing I can think of, the phone/SD Card/ROM have been 100% reliable so far.
LUCKILY, I made a rare backup of my SD Card yesterday. I usually remember to make one once in a blue moon.
All I can think is to recommend folks to disconnect the USB drive when not needed and do Backups (of the Phone and also the SD Card).
Anyone seen this before ??
sorry to say this to you but your memory card has gone corrupted.
i know this because this has happened to me alot of times.
this happens if you use unbranded memory cards but this also happens to branded memory card.
the only solution i can give to you is buy a new memory card. and the main reason this happen when you connect your phone to your pc/laptop and use it as diskdrive and take the wire out while transferring data.
the only way to prevent is to use a safe remove usb and than change your diskdrive to charge only and wait till everything is loaded and then disconnect your usb wire.
also if you fornat your memory card it will work but i can tell you this that this willhappen again and this could happen without connecting your phone to computer. so to only prevent data loss buy a good new memory card.

Correct me if I'm wrong but I'm 99.8% sure it still works and he doesn't have to buy a new memory card yet .. I don't know where you get the idea that his memory card is completely dead! It looks like he still has his files, there's just all that junk in there! Worse comes to worst, he has to reformat it which I think may not even be necessary
Anyway, I've had a similar situation as yours and "repairing it" fixed those issues up. I didn't even reformat it, just repaired it. Try that! (Assuming you haven't already reformatted it anyway)

Update:
Card is fine. Just the filenames/pathnames got screwed.
As I said luckily I had done a backup of it yesterday, only by accident. I mounted the card on the PC directly (USB adapter) and deleted / copied stuff back.
It must have been something on my PC I ran as it changed the filenames/pathnames to 8.3. I did run something (can't remember the name) as I had problems doing the copy (SD Card to PC) for the backup. A few (4 if I remember) files were too long, exceeded the 255 limit. I D/L something to see what was the issue, turned out to be some book preview I'd accidently down loaded from the market.
All good and working now....
As I said just a warning that **** on the PC can screw the SD Card on the phone.
Backups (Nandroid and SD Card) are a pain but can be life savers.

i don't mean that he should buy a new memroy card because after formating/repairing it the memroy card will work but this corruption can happen again. if this happens again the onl;y thing he can do is buy another memroy card. this has hapened to my unbranded memroy card which was 16 gb class 10 and it happened atleast 5-6 times. since i couldn't take another corruption i have ordeered class 10 32gb lexar memory card which is working fine and its hasn't gave me any problem since i've been using it
Man that's what happened to one of my other 4 gb cards I don't use anymore. It was kinda funny. I ended up reformatting it, but an odd thing has happened... 3gbs went down to 1.7gbs... I can't even access the remaining 2gbs... no matter what I've tried.
I didn't buy a new card since it works just fine. Been using it as a "mini" file storage card for 4 months and no issues yet. =D
You sure everythings fine? A lot of files on that card read "0KB" which is definitely not a good thing.
Best of luck.
Anyone with any issues with an SD card should first attempt a low level format.
I'll leave you all to Google that one.
Sent from my MyTouch_4G_Slide
It's fine.
Just that something I used, never used it before, to check filename/pathname lengths (due to FAT issues), seems to have converted everything to DOS 8.3 format. The ones that didn't conform to that were created after a phone re-boot.
This was only as a warning that **** does happen and backups, while a pain in the arse to do, can save a load of pain.
Off to try some ICS ROMs now so expecting a load more pain, d/l, CWM, Wipe, Swear, revert back to CM7. ;-)))) Just need to make sure that nothing updates my HBOOT..
Try .. A Full format of the SD Card
You need to do a Full format and wipe of the SD Card .. I have " fixed" a few this way.
I use: HP USB Disk Storage Format Tool - Seems to work for me
Moving the intent of a few posts on LineageOS thread to here.

Hi everyone,
Some of you reported that SD Card stopped working. This happened to me too today after about 20 hours after the latest update. The case with me is it doesn't fix itself even after a restart. I'm kind of stuck, whatever I want to do with the SD Card it wants me format it. I always had it as internal storage with apps and other things there. I have the the backup from the before the update. Will that fix if I restore it? Just want to mention that I update every week and never missed one. I had very minor issues up until now. Week in and week out everything has been fine and I started using the rom with the first release, all clean, full format and then weekly over the air updates every single week.
If anybody know any solution please let me know, if nothing works or I don't hear anything I'll probably try the backup restoration. BTW, to be specific about SD card no working I always get two notifications, one is "Unsupported SanDisk SD card" and the other is "SanDisk SD card missing"
Thank you

Thank you for you help, I really appreciate it. The problem I see, right or wrong, is that I had this card for a year with no issues, first under stock rom, then under CM, and now under LineageOS up until the latest update with no issues at all. So it's just hard for me to take the card as the problem. Especially after seeing other people reporting it too lately. Do you have more information than just that? Meaning LineageOS and won't ever get along with sandisk or size larger than 32GB because of some external hardware limitation or something like that. Or this is just general knowledge what works best with LineageOS? In the first case I can think about case I can go and invest into a new card but in the second case I can just wait it out until codebase improves. It would good to know more so I can make better decisions.
Thanks for your help again.

+1 @KrisM22. I agree that almost all the users that state that there's a problem with their SD card were using a SanDisk SD card including myself. @rb1979, if you really think that your card isn't faulty, then try using it in some other phone. If you face the same errors then your card is faulty. If it works fine on the other phone, only then can it be considered as a problem with the ROM.

That's most of it - then it goes verbose and wobbly.
I welcome any and all comments about SDcards!
There is no OT here but remember the XDA rules and try to be nice to folks. You can learn without trying to control others' behaviour.
No need to pretend you are TD. (allusion to Alice in Wonderland - Top Doormouse)
Thanks for creating this thread. There are surprisingly few other recent threads that discuss this topic on XDA apart from the one I've previously linked to (https://forum.xda-developers.com/android/help/micro-sd-write-access-format-exfat-t3358275). Also, I'm bringing over the well informed SD related comments that you left behind.
---------------------------
I've got to push back on the apriori assumption that these are specifically Sandisk brand card issues without knowing the specific details of the issues and seeing actual logs, and also without knowing the history of the individual cards in question (details of every device it was connected to and how it was connected, what OS and what file management methods were used, and how full the card typically is, and how frequently it might be disconnected in the middle of a file operations, among other things).
We must be mindful of the fact that the majority of SD cards in circulation are Sandisk cards which means that the majority of reported problems will be on Sandisk cards but this does not mean that the Sandisk cards are experiencing proportionately more issues than other brands. I don't doubt individual experiences, but it they may not speak to a larger picture. For example: Having supported large systems (>300 devices) running Linux directly from SD cards I did not see more problems with Sandisk cards than others. We've not seen enough evidence here to declare that this this is a Sandisk problem.

The fact that a card has been used for a long time under different circumstances does not support a logical argument that the problem is in the ROM, in fact that supports the logical argument that the problem is with the card.

Good advise since, if the cards is having problems it should bring the problems to the other devices. Testing a different card in the first device on which the problem was noticed is also a good test.
--------------------------
Here is some supplemental information specific to Sandisk SD cards' built in data protection on cards experiencing failure. https://forum.xda-developers.com/android/help/micro-sd-write-access-format-exfat-t3358275. To summarize what is there: An SD card may begin to fail unknown to us, and then when the built in data protection is invoked it "breaks" the card with a dirty bit at beginning of drive so it cannot be written to or formatted but still allows us to copy data. The symoptoms when that data protection is invoked are similar to those bing reported by people who can no longer mount the card in Android devices (Android devices require read and write access to mount the card, unlike when the card is access via card reader on computer).
Just an update. I tried to format the card as portable storage (after this failure as internal and being burned I have hard time trusting it now) but it fails. I didn't do any testing with other phones just went straight for format. I might just buy another card. I think the phone specs say it's 32 GB max, is it still the case with different OS or not (meaning it was due to software not hardware) if I could get something higher than 32 (the current broken one is 32) I would go for it.
Thanks

I believe after you use it as internal, and then try to use it as external, you first have to write an MBR on it and a partition formatted FAT32. i use a bootable stand-alone GPARTED to do that.
http://gparted.org/
Moto says it's limit is 32GB. Folks have, I believe, used much bigger cards on it. Don't know what is the limiting factor - be it software (ROM) , hardware, or licensing (exfat for Microsoft). I have ordered a 64GB Sammy which I should get in 1/2 week so I can test. Course I wouldn't be doing exactly what you would be doing so the test would only show that the G3 could read/write to it. I will only use it as external storage. I don't really "need" 64GB but it will allow me to be a bit more sloppy vis a vis nandroid backups.
It could be that after you format yours, that it will suddenly work just fine. Then again I just had a thumb drive go belly-up from I/O errors - once in a great while, it happens.

I've got a 128gb in my Moto G (3rd - XT1540 2GB), and I have used the card for a long time. It works just fine for me, and the space is obviously fantastic to have. Every now and then (every few months or so, I'd say - maybe 3 times in the 18 months I've had it), it does become corrupted, though, and I get those same error messages. A backup, wipe/re-format, and restore, and I put it right back in my phone and it works just fine again. Seems like that's happened in other devices, though, too.
The card is a SanDisk Ultra SL128 (Class 10/UHS-1, man'd Jan 2016). I've only ever used it for external storage, never adopted, and I've only ever formatted the card as FAT32, using my PC. I'm running stock Android 6.0 24.24.1 at the moment, with TWRP.

Thanks - Becoming corrupted every 6 months seems excessive, but with heavy use...? So what do you use it for? Also it sounds like you are using something other than the phone to format it...?
At least you are ready for it and just re-format it!

That may not be drive corruption but rather a corrupted file or files. If it is localize drive corruption it may still be there without having any impact until some data is written to that part of the drive. Unlike platter based hard drives, when these drives actually start to fail they may invoke a built in data protection (dirty bit) which resembles being locked in read only mode preventing the drive from being formatted which is obviously not your case. Have you ever done a sector scan of the drive, eg chkdsk <driveletter> /f /r or done a full format (as opposed to quick format)? Either of those things may flush out localized damage and the scan might fix it but they would take a long time.

Yeah I guess it is kinda a small PITA lol. Could just be from me starting and cancelling or moving too many things at once, I don't know.
I've never actually come close to needing all that space to TBH. I could probably do just fine with a 64, but it's nice to know I could record or store hours of HD video, for example, if I need it. I got nearly 30 gigs of music on it. I keep tv and movies on there, too, in case I get caught bored somewhere. Full Nandroid and Titanium backups are on there, as well.
I use a microSD adapter and a small (76 kb) utility for Windows called FAT32Format (Ridgecorp).

That may not be drive corruption but rather a corrupted file or files. If it is localize drive corruption it may still be there without having any impact until some data is written to that part of the drive. Unlike platter based hard drives, when these drives actually start to fail they may invoke a built in data protection (dirty bit) which resembles being locked in read only mode preventing the drive from being formatted which is obviously not your case. Have you ever done a sector scan of the drive, eg chkdsk <driveletter> /f /r or done a full format (as opposed to quick format)? Either of those things may flush out localized damage and the scan might fix it but they would take a long time.

I've had that problem before, too, but not on the 128 I have in my phone now. That is very frustrating. One of my 32 gb cards suddenly went into "read-only" mode as you describe, and nothing I can do will get it useable again. All the files are still readable from it (except the part of one huge video file that is on the bad sector that seems to have caused the problem).
So right, my 128 card doesn't have that problem, and seems to be corrupted files, as you say, not the drive itself. I do actually do what you talk about - when I do find I have to re-do the 128 sd card in my phone, I run a Windows chkdsk /r before I re-format it, and a chkdsk /f afterward, as a check. The chkdsk /r does take quite a while, yeah .. a few hours.
Cheers

Great that you're running chkdsk on it. May be caused if you cancel or something happens in the middle of a move. Only other thing I could suggest is to do your format on the phone itself, after you've done everything else on the PC. Don't know if that would make a difference. Shouldn't but I've run across vy experienced folks saying to do that. But... Yeah you've got me hankering to put a 128GB on it...
edit: for read only cards before you trash them I would run them by gparted just to see if re-creating the MBR and partition would change its mind. I have successfully done that with thumb drives but not with cards/adapter/reader.

Yeah, thanks for reminding me about fixing the errors, IronTechmonkey. It's kinda an important step I forgot to mention.
I not sure I have the bad card still. I didn't think about GParted, should have. I tried Paragon, among other things, but to no avail.
What speeds are folks getting from a U3 SDE card? I bought what I thought was a 100/60MB/s card and it does about what my old PNY card did - R=40-50, W=34-40MB/s. Is the phone the limiting factor or did I get a bum card?

AFAIK the the phone hardware/OS is unlikely to meet the advertised speeds of the cards. Likewise and perhaps more so for USB 2.0 ports and anything using MTP.
I dont know how this compares but for what it is worth: With a Sandisk Utra SDHC (Class 10 - Video, Ultra High Speed Class 1 - whatever that jargon means) touting 80 MB/s read speeds and 40 MB/s* write speeds; the read speeds did consistently approach the rating (getting hot enough to scorch the logo) and the wite speed occasional did. Another factor is the size of files being copied, larger quantities of smaller files taking more time per MB, unless using some dedicated test utility I've never actually done a test of SD r/w speeds on the device. What are you using to measure those?
* In re write speed ratings: Digging into the small print of the specifications may reveal that the manufacturer uses different size cards each for the reed and write speed ratings, effectively padding the write speeds by citing test results from smaller capacity cards.

Thanks.
Interesting - so you were testing it on windows (?) I did test them on linux and got W=74 on the PNY and 77MBs on the Samsung. That's through a USB3 cardreader.
On the phone I used A1 SD Bench, SD card test, and disk speed test.
Off to try windows...
I was just going to boot up a WinPE and test it there. What prog did you use to test it?
Yes, both of these cards test at about R=81 , W=66.

Yes, Windows 7, which reports file data transfer speeds in the copy process window so I did not use a utility. I've done this enough times in geneal, and a few times specifically with large files and a stopwatch, so I know the speed in the file copy window is relatively accurate (for single large files). The speeds you get on linux seem reasonable. I'll test A1 SD Bench on Osprey when I have a chance. Thanks.

Also seemingly reasonable.
My card seem to be working just fine on my Lineage OS. I rebooted by device and now it says it's corrupted. Is there any way out? Will I be able to get my data back?

My suggestion would be to copy whatever you can off it and re-format it asap. If you can't read it via phone, try PC.
EDIT: I am assuming you are using it as external. If you are using it as internal, I believe you have lost everything. I know of nothing that can read it. GPARTED can only re-add an MBR and a partition and make it usable again, but all data is lost.

Yeah. I copied everything and made a backup. Luckily I use it only as a storage device and not an internal drive for apps. But how do I re-format it? I tried using the format option that my phone gives me but to no avail.

Do you have a little card reader so you can plug it into your PC?

No. Sadly I don't. Is there no other way round to format it?
