Twice in the last two months my 16 GB Class 6 AData microSDHC memory card has popped up as being "corrupt" and needed reformatting after powering back up from reboot on my Nexus One.
The first time happened on CM 5.0.3.1, the second time was with CM 5.0.4.1 with the UV kernel. Both times, data could not be read either through the N1, my old G1, or my friend's Droid. Thus a reformat was required and data loss ensued.
Anyone else experiencing occasional data corruption on their SD card? Another friend had it happen to his G1 with an 8 GB microSDHC memory card recently, running the latest CM for the G1, also on reboot and battery swap.
Is there a common thread here? Could it be HTC hardware-related? CM software-related? Just coincidentally two bad memory cards? Me using chinese replacement batteries when swapping out? The UV kernel? Not trying to point fingers or throw stones, just trying to get to the bottom of this...just lost some great pics of a recent vacation I just got back from. Suggestions or hints are welcome!
TIA!
this has happened to me a few times but I was still able to get my data through amon-ra recovery. I think it have something to do with an improper dismount of the card.
I'm curious, what brand of memory were your friends using?
I actually had this happen when my n1 was still stock (16gb class6 card)
I put the sd card in a card reader on my pc, everything was intact so I backed it up, reformatted and still had the n1 report it was corrupt. I ended up having to shut down, remove card, boot up w/o a sd card in, then with the sd card back in I never had the problem again
I know I did a full format the very first time, that 2nd time I had done a quick format. I've done a format recently also via amonra for ext partition and still no problems.
I happend to me few weeks ago. After turned it on ... I couldn't do anything because the screen was black and any key or type of touch was useful ... so I removed the battery and at the next start the SD wasn't readable anymore!
sry 4 my bad english!

i'm running a 16 GD Class 6 AData memcard in my N1, my friend is running an 8 GB class 6 SanDisk memcard in his G1. Neither of us is running Apps2SD or anything weird.
glad to see i'm not the only one with this issue. was gonna buy a new 16 GB card but saw an article yesterday that sandisk is coming out with a 32 GB class 6 sdhc card in a month so i'll just wait for that one.
Same here
Same thing has happened three times on my Sandisk 16gb. I am running stock everything on nexus..nothing funky app wise.
After the first time it happened I replaced the sd card. It still happens. I have never been able to fix the card other than reformating. Chkdsk /f on win7 gets to 98% then throws an i/o error.
There is something majorly wrong. It seems that it happens in all android phones from time to time not just the nexus one. The consensus online seems to be that it is a mount/dismount issue that corrupts the card. I never mounted or dismounted the card at all with PC and it still happens so not sure what else it could be.
Do you think it is a phone hardware issue that would resolve with a new handset?
Has this ever happened to anybody using the standard 4GB card?
Where did you purchase your micro SD cards? There are a lot of fake/faulty cards being sold. I bought a fake one (unknowingly, obviously) and it kept getting corrupted until I tested it properly using h2testw.
I have the same problem on my nexus! I use an LG 16GB Card and CyanogenMod-5.0.5.3-N1! Any way of recovering the data without amon-ra?

+1 Make sure you dismount from computer first...otherwise this problem will pop up again...and may not be correctable next time. (There's a reason why the phone asks you to properly dismount from computer first)
no **** my n1 has the error message damaged sd card. restarted the phone a couple times and same message. what should i do? i see peoples solutions on this thread but idk where to start. i have a rooted n1 running cyan 5053 with apps2sd
I have had this problem a couple of times too, the latest being this morning
I have a stock N1 with a 16GB Sandisk card. The first time this happened, i went to use the camera and it said insert SD card, even though there was one there, I rebooted the phone and then got the Damaged SD card message.
This morning I was on the train, had been using the phone to read the news earlier with no problems, I got it out of my pocket and screen was black. and the phone completely unresponsive. Removed and replaced battery, booted up and got the Damaged sd card message again.
Both times I have been able to recover most of my files by putting the card in a PC, the first time I found that a couple of my photos were corrupted and unrecoverable, indicating that possibly it was the camera app that may have caused the issue the first time.
This time though, I found that some of my music tracks were corrupted along with one of my videos, and also a directory on the SD called LOST.DIR. Everything else was fine.
Not sure why only these files were affected, as I was not listening to music or watching any videos, so I dont see why the nexus one should have been accessing those parts of the card when it corrupted.
I could not delete the corrupted files, even on my PC, accessing them causes the PC to lock up. The only way to get card working again seems to be a format.
If only the format would work!

Just happened to me as well. Genuine 8gb Sandisk, class 4.
After a reboot Nexus reports corrupted card. It really seems corrupted, I'm unable to read it in a PC or anything else:
[ 1042.673542] sd 11:0:0:0: [sdb] Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE
[ 1042.673551] sd 11:0:0:0: [sdb] Sense Key : Medium Error [current]
[ 1042.673561] sd 11:0:0:0: [sdb] Add. Sense: Unrecovered read error
[ 1042.673571] end_request: I/O error, dev sdb, sector 10248
I'm using CM 5.0.4.1 with UV kernel.
It's happened to me, even using the "safely remove hardware" function on the pc. i started just using the unmount on the phone which seemed less problematic.
Yep...add me to the list. Running stock N1 was playing music when it ocurred it started skipping through the tracks fast right before it stopped. It has affected/removed all my pics and left the music.
I'm with you all:
2 times on my Motorola Milestone, using a 16GB class 4 "unbranded" card
3 times on my Nexus, using that same 16GB class 4 card.
2 times on my Nexus, with a 16GB class 6 SanDisk card.
Most times, the data has been available by mounting the card into a PC or Mac directly, though my Mac has seen the card as "read-only" in these cases.
I seem to have this problem after mounting the card onto my work PC, though I don't often do that. I mostly use ADB to copy files. Maybe it is linked to leaving the debugging interface up all the time? I do that and I'm sure that most of you do as well...
Me too
I am using FRF91 MRCr21 and I am on a 800mv 070810 .35 rc4 kernel. Newest 5.00.08.04 radio.
Twice now after using quickboot my phone has reported my SD card damaged and it says I will have to reformat. It is a 8gb class 2 sandisk, real. One time I used quickboot to enter recovery mode and the other was only to reboot the phone. Has anyone else had this problem? What is the best fix? Both times I rebooted my phone was stable. I wasn't downloading or installing anything. Thanks!
My phone can't read the card. If I pull the card and put it directly in my computer it won't read either. Both OS can't read the file system and want me to reformat.
Neither happened due to not dismounting. Anyone correlate the problem with quickboot?
have had zero luck with adata 16GB classs 6 cards. i have gone through 2 of them however their 8 GB card has been awesome
Just had this with a Sandisk 16GB Class 2 card. Inserted into card reader, copied something, popped it back into the phone, corrupt card message. Even the computer says I have to format it.
so i just got my buddies old g1 to mess around with. it didnt function at all when he gave it to me, had to doa hard reset to get it to boot. but the problem im having is the sd car says its blank and doesn't format or anything. ive tried different sd cards and they all work in the comp,i reformatted 2 of em. ive searched google for an answer but cant get it to happen. anyone got any suggestions or could the internal sd slot be shot?
does recognize when a sd card is inserted and removed
does not recognize or format any data on the sd card
is there any way to fix this? and would it be a hardware issue or software?
It sounds to me like the sd card reader built into the phone is broken.
Yea that's what I thought, is that seperate from the mainboard?

yea i got the same thing but im not good with adb enuff to flash a diff rom back to where i can use phone memory for pics and apps any sugestions? on how to do that?
Hey guys
Okay straight to the weird problems I am experiencing
Running darkys 8.1
First is that when I plug my phone to the computer i only get access to my internal sd card while the external stays slightly transparent and can't open. Used to get both opening up but now only Internal sd card Happened a while ago but paid no heed to it and now i guess i am paying for it. have trying dual mounting and other things to try to get it to work but no luck.
Secondly I just recently got a 32gb the new sd card( promblem number 1 still persisting with the new sd card aswell) and it seems all the videos I put on it start to get corrupted one by one. I would watch the video and 10 mins later I get unsupported file type. Which is kind of weird as everything would be good and few seconds later half of my videos are useless.
Allready formated sd card several times ones through the computer and twice through phone.
Thanks for reading!

Try to transfer data thoruhg a card reader. Especially if it is a large amount like 3-5g of music. Moving data through the phone is fine in short bursts but I always founf it to be cleaner and faster through a card reader.

Speaking of memory cards, how did you fix your 32gb Woodrube? I have 3 sd cards failing on me and not sure why. They work for a bit then fail again.

Man it sucked big time for so long but I was able to find a corrupted file on there and had to use File Assassin from Malwarebytes.org to delete it. Even then, it didn't want to go. I reformated it full fat and used the "slow" process that filled in 1's and 0's. It happened when I went to CM6.1 the first time.
Think I may have borked it myself during an bad install and then it would never work correctly. I use MiniTool Partition Wizard (I don't like GParted b/c you lose all your data. With MTPW, your FAT data is still there when you want to resize yout ext/swap) to set my partitions and once that was done, I would try to reinstall that same file. Wasn't until I figured out that it was causing so many problems, but it was the only ROM that would boot up. If I used it and then wanted to go to Wanhu or HM's ROMs (this was a few months ago), when I would restore those, it would break the partition and would never boot up. Wouldn't loop in the traditional sense where the animation would run then disappear and the run again, it would just continually run.
Not saying it is CM6 or anything like that, I just think I got a bad download or operator error and a corrupt file hit my card. I just reformatted to full Fat and no partitions and it works fine (for now). It was only the partitions that would not work. I would run MZor sd-ext test and it was horrible with all the errors it showed. I had been deciding to format full fat anyways and stay away from partitioning (I don't and never have used swap), and I have to say I think it is really better that way. I only have about 50+/-apps so my Dalvik isn't even close to filling up and half of them I don't even use.
OK thanks buddy! Looks like thats what I might have to do. So what would be the best method to move Apps over then with just fat32? If you have any advice for me I sure would appreciate it

On my wife's XT, i am just using the native Froyo app2sd (settings>manage apps>select app>move to sd [there is also an app in the market called Move2sd enabler that will move "non-movable" apps to the SD card]). Don't move any widgets to SD card though. On my Vibrant, I have't moved a single one over to the SD yet and have 1.5g left on internal.
FYI if you get an error when downloading an app from the market and it says,
"App not installed
Unknown Error-18"
Don't freak out, it is a known Froyo bug. All you have to do is plug your phone into your computer and look in the .Androidsecure folder (make sure you have show hidden folders checked on your PC) and delete this file.
smdl2tmp1.asec
You can do it through terminal on your phone too but sometimes it repopulates if you do it this way
su
rm mnt/secure/asec/smdl2tmp1.asec
Sorry for the thread hijack but it is kind of a fix for some SD problems.
the original microSD that came with the phone is kinda shady
mine had some problems, had to format it twice to get it working right
a friend of mine even worse, after a few use it died completely
A friend of mine has a LG Marquee from Boost Mobile and he is having a problem which is a little weird.
The when I install Speech Synthesis from the market place it installs fine but when I go to run the program it wants to install data to the SD card which is normal. But this isn't normal. It doesn't detect the SD card and wants me try again.
This is a new 32 GB card from Sandisk he bought two of them and they both have the same issue. I tried a 2, 4 and 16 GB card thinking there was something wrong with that but they didn't work either. It just wont in see the SD card.
This is not the only program. The stock music app doesn't see the music on the SD card either.
When saving music today to the card from the Android Market place to the SD card it says its full. I know its not there is barely anything on it.
In an effort to fix this I did manage to root the phone. But that didn't seem to help much either...
But I know its working because if I run any other program it finds the card with no problem. I stuck the card in my own phone and it works fine. Sooo...
HELP!!!
Thank you so much..
Hey I have thag same phone but I don't have that issue like your friend is havong with his. Have you tried to format it in the phone? I took my old 8gb sd card out of my old android phone and it works fine. The phone itself may be defective. If u haven't tried to format the card in the phone I would do that first
Sent from my LG-LG855 using xda premium
I did that with other cards and with no avail. So I'm not sure if its a defective phone because the SD card reads normally on other apps with no problem.
