Couple months ago I got one of those fancy 16 GB microSD cards for my Vogue. This morning I woke up and saw that my regular backup (with Sprite) had completed. But I also quickly discovered that my card (where backups are stored to) had a corrupt file system.
Plugged it into Windows and did a couple of repair attempts, but nothing worked. Sighed and went to format option. After this it appeared to be successful except for the last line of the job - the dreaded "Track 0 is bad. Disk is unusable. You are totally screwed." message.
I can (and have done) some basic troubleshooting, but this one is beyond me. Is there a way to recover from this, or can I just throw the card into the trash?

Wondering if anyone can think of anything I can try before returning the phone this afternoon.
What happened:
Yesterday, I rebooted the phone because a prog had hung and wasn't responding to force quitting via Applications. When I tried to turn it on, it didn't respond -- zilch. I plugged it in and tried a few times to turn it on over the next hour with no luck. Finally it started to boot and hung at the ATT screen, but after sitting there for a min, horizontal lines appeared across the screen. Tried again over the next hours with the same result.
Left the battery out overnight. A few minutes ago, I tried it again and it actually got past the ATT screens, but after the Samsung logo sequence was done it hung on the blank screen. The phone is rooted and clockworkmoded, so I tried to boot into recovery to do a nandroid restore. No dice: I get an error about not being able to write/read to the sdcard.
So at the black screen, I can shell into the phone. Can't SU (seg fault). Can't get to the internal SD storage (which is all I really want at this pt. I took a bunch of awesome pics while surfing yesterday and want em).
It looks to me like there is some sort of corruption of the internal storage. Any thoughts would be appreciated.
From the looks of it your nand crapped out...

Yeah thats what I'm thinking.
This does highlight a flaw in the storage setup: having internal storage like the iphone is seriously awesome from the usability standpoint. But android is set up to assume that when you back up, it's to a removable card. So I have a Ti backup, but that doesnt help me if I can't get to it if the phone dies.
Seriously bummed. I've had a really crazy # of dead iphones (like 6 over two models -- its one of the reasons I finally switched) but the upside was that when it was switched out I was rocking all my stuff on the new phone within an hour. With this, I'm now starting from scratch.
FWIW: I got the phone working again by wiping user data and reformatting the internal storage. I'm guessing that there was something corrupted.
Here's the warning I'd offer though: Ti backups etc do you no good if they're on the same file system as the phone boots off of. I was backing up regularly, but since they were on the internal drive that did me no good. Unless I'm missing something, Ti doesn't allow you to choose a location (just a folder name) for backups.
if it lets you choose a folder name then choose sdcard/sd that is where the phone's linux mounts your external SD Card.
Also I keep my Titanium backups and Nandroids on my Computer for extra safety.
Hello all!
<Story>
I recently noticed that I was receiving a ton of Force Close messages on my HD2 and decided to restart the device (which I hadn't done in a while:laugh. When the device started back up, I realized the apps that were reported to have force closed, hadn't actually crashed.
Then I noticed that K9 mail was going crazy, showing the "updating" notification every half second on each account. When I decided to read my mail, it seemed as if they were all from the previous day, showing up as unread! Then I went to open the new version of Firefox, which I had just read about and installed ... but it was nowhere to be found.
Since I was sitting next to my computer at the time, I quickly looked up some stuff on xda and saw people were recommending CatLog, which I immediately installed. Upon attempting to open the application, I was met by a barrage of force closes including system and Trebuchet.
Panicking, I pulled the battery, cleared the Dalvik cache and fixed permissions, which unusually, completed instantaneously. I attempted to reinstall Amarullz's a2sd script but after copying it from my computer to the SD and booting to Recovery, I never saw the file I was looking for. Trying this process a couple more times, I honestly questioned my sanity but then speculated senility ... I DID just copy that file, didn't I?
</Story>
Apologies for making you read that, but I pushed the problem aside and used my phone for two more days (it was painful) before finally writing this.
EDIT: RELEVANT STUFF BELOW, STORY ABOVE
I did some testing and it seems like my SD card is somehow bugged but nothing really confirms it, diskcheck says everything is fine. Windows explorer doesn't complain while copying. And files that are copied DO work until the card is ejected, at which point it reverts back to the prior state :/
EDIT 2:
downloaded TeraCopy and verified my copied data (see screenshots)
Funny thing is that the data copied is NOT the same - the checksum indicates corruption, but when I tried it again, the checksums were the same! When I open the video files, music I had copied onto the card a week earlier began playing!
Is this thing read-only? The card is not full, neither is it a fake.
Formatting the card in Windows 7 causes a "windows was unable to complete the format" error when 2/3 complete (not quick format)
Even though it seems that it was mostly formatted, the data is still intact. Quite odd.
microSD Card Details:
Manufacturer: Apacer
Size: 16GB
Partitions: 2: FAT32 and ext3
TL;DR: ???Read-only??? microSD card but not sure: no errors while writing data, no errors reported by diskcheck, no corrupt data.
Same thing happened last week
I had the same thing last week with a 16GB SanDisk in my Nexus One running CM7.2. It started with a couple of force closes, then after a reboot just about every application (over 100 on sd-ext with S2E) force closed and the system became unusable. Tried various things and eventually found out that I could write to the card without any error, the files seemed to be there but were gone when I reinserted the card. Even deleting a partition from gparted on Linux showed no error but the partition was still there. The card is 18 months old, I sent it in under warranty.
Hello everyone!
TL;DR: Got a faulty Samsung card which reloads on any device constantly, can't perform formatting or safe-erasing.
So I bought this Samsung Class 10 EVO 32G card for my CM12.1'ed Galaxy Tab Pro 8.4 in June, and it ran smooth and fast until... about a week ago I left my tablet on one night (with charger), uploading traveling photos for backup at a slow upload speed hotel room. I got up to check my tablet in the morning and I kept getting an notification saying "Checking SD card for errors" and stuff. The notification appeared for about seconds, then reloaded itself (disappearing then popping out), again and again. :crying:
It seems that the tablet couldn't hold up the communication with the SD card for longer than a blink... At first I thought it might be my tablet too hot last night (it's cool in the morning though) and burned the card reader module, so I instantly turned off the device and removed the card.
It turned out that the tablet is ok and it was my card's fault... The backup failed within one hour after I went to bed. I got the same problem plugging it in my phone or PC. I can see the root directory in Window's Explorer, and if I'm quick, I can manage to open a few folders and see the files ok, except I lost all my recent documents and photos into a 20GB giant LOST.DIR folder... When a 5-second or so period expires, the explorer hangs and I guess the card got disconnected again...
I contacted the retailer for the issue. They offered a replacement but not a fix to save my precious data. I searched online for hours but don't seem to find a useful answer... Later I found that the card wont disconnect when I switch on the READ ONLY mode on my SD adapter (!). This discovery almost made me cry!!! :victory::victory::victory: I then managed to recover some of the lost files, minimizing the damage, but I find myself unable to format the card or safe-erase any files since once I switch off the READ ONLY, I won't get a steady mount. Even a delete or copy command will hang the system. That's a huge problem because I have quite some sensitive files, passwords laying there, reachable once you enable READ ONLY mode... But I can only get a replacement when I return the faulty card.
How can I safe-erase a card in my situation? Is there any software good at this? I'm really desperate for some help! Thank you very much in advance! :laugh::laugh::laugh:
Hi!
I've got this HTC One A9 just about a week ago, and took it with me on vacation last Saturday until today. Last Monday on my birthday, I used the phone to take a lot of pictures from a zoo and everything - with every picture being saved on my SanDisk Ultra 32 GB microSDHC, formatted as adaptive storage on my A9. Suddenly, the day after my Birthday, I took some more pictures and suddenly the SDcard was unmounted from my phone - it said that the SDcard was unavailable and I had to re-format it, to set it up as adaptive storage again. I had to hard reset my A9 and set it up as a new phone, as almost all of my apps was installed on the SD-card too, and was just greyed out with a little Android in the corner, holding an SD-card.
I tried to see if I could access the card from a file manager in the phone, which wasn't succesful, and today when I got back from my holiday, I've tried 8 or 9 different SD Card recovery programs on my computer, trying to restore the pictures on my SD card - though it only recovered the pictures, that was taken by the former owner of the SD card! So it looked like that all my pictures was deleted right away, when the error was occurring last Tuesday. I've now reformatted the card, again with no luck in restoring my own pictures, as I thought it could help.
Have anyone else experienced this problem with their A9 or with any Marshmallow phone using adaptive storage? I'm afraid, even though I'm using another SD-card in my A9 right now, to use the SD-card as an internal storage.
So around a week or so ago, I started getting this unsupported SD card message. I have seen this happen in the past with the last OS version and would simply reformat the card since it was seemed to be the easiest way to get things back to normal. Now, however, the phone will not format it. It tries and then delivers the message "command '7 volume partition disk: 179,0 public' failed with '400 7 Command failed'" Every time I attempt another reformat, the first and last number (7 above) increment by one.
The first logical conclusion that I came to was that the SD card is corrupt or bad. So I took it out and with a reader, attempted to access it with my my Windows laptop. I could browse the card with no problem so I copied the data and then reformatted the card to FAT32. After reinserting into the phone, it still won't format and I get the above message.
I, again, thought maybe it was the SD card so I tried another. Same thing....tried another....same thing. I've tried multiple cards no with no difference.
The first SD card is a Transcend 32GB Class 10 card and the other cards I tried are all Samsung 8GB Class 10. The phone is running Android version 7.0.
I have attempted the following with no change....factory reset, wiped the cache, booted into safe mode, and reformatting the card using both Windows DiskManagement (both quick and slow method) and GParted.
A search of this forum returned a few hits related to this type of error message but no apparent resolution or cause. Everything is pointing back to the phone as the culprit, but I'm just not sure if it's software in nature or hardware. I'm hoping it's the first as that would lead me to believe there is a possible fix for it.
Anyone have any ideas?
So I just got off of a chat with a Samsung support representative and they've instructed me to send the device in for repair. Unfortunately, this begin my work phone, I can't afford to do this since other than the SD card, the phone works beautifully.
I did ask the rep what they got in the way of a search return for the message shown above and was basically told no. I do find it hard to believe that though since there are numerous people who have experienced similar incidents.
