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!
erikikaz:
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 purchased 8GB SanDisc micro SD card 4-5 months ago and it started to acting weird. When browsing pictures, some pictures have glitches meaning half picture is bluish and half greenish, sometimes redish.
Disconnecting and connecting SD card solves the problem but after several days problem continues. Few days ago I received message that my SD card is broken and it needs to be formatted. I formatted it and it worked 2-3 days and then again started to act weird.
Is my SD card broken or maybe it is phone? Someone else with such experience?
Thanks.
Same story here. This has happened with 2 out of 3 cards i have owned.

Really strange. It is important to detect are there really broken SD cards or our phones make bad SD card under some conditions/roots/ROMs. Hmmm....
First: when you will have such message, remove it and try to access it on PC. If it will work on PC - then it is the phone problem.
If not... well, where have you purchased it? SanDisc cards are covered by Lifetime Warranty, and thing what you have to do is to make claim.
Of course, if you have bought it for bargain price on eBay from China, then...
Thanks. I bought it in Mediamarkt, regular store for IT accessories. I will make a claim if this problem repeat.
I had the same problem with 16GB sandisk card so replaced it (JB hifi - reliable Aus store who replaced it for free). Same prob with new card though. both cards reformatted many times but still no joy.
photos taken with phone cam and saved to int SD no problem, but every so often if saved to ext SD the glitch occurs. Photos taken with a digicam then transferred to SD same prob - randomly in gallery won't show some photos properly.
Also discovered that videos made on pc (like clips from films my son likes) but put on ext SD often don't play well or stop before end of clip - no problem if saved to int SD.
I figured it was a bug with the SGS in dealing with files on ext SD - super annoying but have basically accepted it as can't find anyway to fix it!
FYI Recuva is a great program to retrieve lost files

forgot to mention that on my phone, it only seems that photos or videos are affected by this glitch.
I have mp3 files, homemade ringtones and word docs on the ext SD and so far (touch wood) haven't had any problems with using them or viewing them etc.
DoctorV, exact my story. I am assuming that problem is in SGS, although I tried Sandisc 4GB card and 3 days without problems. As soon as I put back Sandisc 8GB, problems started. Very strange and annoying.

Interesting - wonder if it has anything to do with the size of the SD card then? From memory my 2nd 16GB card had no problem for 3 or 4 days too before the issue happened again. Let us know if your 4GB continues to do ok - I may try a smaller card if yours seems to work ok.
thanks
I had 8G SanDisk - no problem for 3 mths, when I replaced it with Sandisk 16G. both were class 6. the second one - 4mths in sgs now - no problem at all.
@doktorV you, in australia, are too close to China, you know
Additional question: which gallery viewer are you using? Both, you that have problems with SD card and you that never had problems with SD card?
I noticed that in QuickPic I picked picture, picture is opened with errors (strange colors or even 3/4 picture is missing) and when I open same picture in stock gallery viewer few minutes later, everything is fine. After opening same picture in QuickPic, it is OK.
After 1-2 hours problem repeats. It is really seems like SW problem and not problem with SD card. Don't know...
I dont know if there is still some activity here..
My sd-card (lexar 8gb SDhc ) is recognized by pc and phone.. after insert it scans.. scan is ok. then a few second - minutes is says sd card is broken and needs to be formatted after format it goes to scan scan ok ... and again broken repeat....
is this a problem with my sd card ? does it matter if its an regular SD or an SDhc ?
and when I format in on pc in wich sort should it be ? stock of ext3 ? or anything like that ?
since im on custom rom now I can format it in my phone ( darknight 4.0.4, when I click format sd card it formats the wrong sd card so I cant use this option )
but its not in the custom rom, had the phone on stock 2.3.6 and the same problem was there. ( also on stock 2.3.3 same problem )
Can I conclude this actually is a '' broken card '' or can I change the settings and make it work ?
thanks in front....
i use an Xperia TL with generic JB Rom, since past few days I get a message "SD Card Removed unexpectedly" and then says scanning SD Card.
Though I never touched anything!
It happens when i try to update senseme feature in walkman, its pretty annoying coz I have 820 tracks and its pain in @SS to resume it every few minutes.
Am I alone or is anyone else in the same boat?
Its a 32GB Sandisk Class 4 card.
The card is not corrupt, as nothing is lot, just that it says SD Card Removed
Try to reformat your sd-card, maybe some strange glitch

I think the sd card is a screw up as I formatted it multiple times on the laptop (Quick format) and even on the phone.
I'm asking the shop to replace it with a class 10 32 gig card.
I did a search and seems am not the only 1, even Samsung Galaxy S3 users are crying in the toilet with this issue.
I am also experiencing this issue with my class 4 san disk micro sd card. Just bought a class 10 will let you know if problem still occurs after sd card is replaced.
I changed to a 32 GB class 10 card yesterday evening, facing absolutely 0 issues.
Previously while downloading music info in sense me (700+ tracks), it used to throw an error that mem card removed after 29 tracks or so and I had to start all over again (was absolutely pissed!), and my favorite marked tracks were also gone once that error showed up.
Not anymore
Btw am using a Samsung Class 10 card (for anyone who is interested)
Interesting. Thanks for posting this. Not to further switch the topic to a different device, but this happened to me on my S3 also. I am using a Sandisk Class 10 64gb MicroSDXC. After it happened, I thought "weird..." Later on, I noticed 3 folders' names had been corrupted (for example, GAME_ROMS changed to ûAMERO~1 or something like that) and the contents of the all 3 folders was gone (deleted - I could tell because the GAME_ROMS folder had 6 gigs or so of games, and aside from it being empty, I had 6 more gigs of free space than usual.)
Thankfully I haven't seen that happen on my Xperia T (yet)... though I've only had it for a couple of weeks... knock wood.
Hi just wondered if anyone has had this problem ?
Ive got 2 sd cards one is 8gb class 2 and one is 32gb class 10 and have tried using them with my xperia sp putting music and films etc on to them

Have you tried formatting the SD card (FAT32)? I too have a 32GB class 10 with 27+GB of music, but I have no problem with the files.

I got same SD as you, but without the problems. Maybe the mounting doesn't work probably on either PC or phone, or you unmounted the SDcard wrong from the PC.
Ive noticed this, deleting files on random times..
i have a 64GB class 10 in mine ,and everything is good
Put the SDcard in your phone and select in settings > Storage > Wipe External SD.
Connect it to your computer again. Put music on it and try again. If it still deletes you need to run a HD check on your SD. Could be that the I/O is defective.
Also; put questions next time in the correct place
Not had the same issue but something very similar.
I had 2 sdcards both by sandisk one a class 10 32gig the other a 32 gig class 4.
When using folder mount app to mount games obb files after maybe 2-3wks they both started to play up not being recognised by phone but working on computer.
Got a TDK 16g class 4 BUT not using folder mount... the card is running happy with it and used for movies and music.
It seems maybe that folder mount in my case was causing the probs with the script it ran and led it to causing the cards to fail.
If you have used folder mount would suggest to stop and get another card.
I don't have any suggestions in how to solve your problem but only another option based on my findings.

I am using Samsung Galaxy note 2 and a song 32gb class 4 SD card. A couple of days back, I noticed that something was missing from my gallery and holy ****..all my pics and videos from the camera folder were missing. There were more than 2000 in number and around 10gb in size. But when I checked for storage size, free space was same.. 4GB even after the loss of 10 GB. I recovered them using Recuva. After recovering the data I did a quick format and moved the data back to memory card. Today when i was in the gym, I noticed that songs were getting repeated very frequently and when I checked, I had only 29 songs left out of 550 and again i was left with the same amount of free space as I had before the loss. I tried to recover it through Recuva, but this time I could recover only 121 songs. I use to swap my card between my htc chacha and note 2, but that's not the first time. And when i recover files from my card, the path shown in Recuva is something like this.

Anybody got an idea, what's the matter? I hate SONY and this is a last Sony product that I have bought in my life. It's my 3rd card which I got as a replacement from the company. I was planning to buy a ps3, but I have changed my mind. I will go for an xbox instead, because after one year of buying my psp one of its button stopped working and company said it can't be repaired.
I have a similar problem. The card disconnects very often and usually many of the stored data become corrupted. I changed the sd with other brand and the same thing happens.
Maybe there is a problem with the sd reader of my note.
Have you tried another microsd to check if it is the microsd's fault before blaming sony?
I guess you didn't read my post properly my friend. I have mentioned that it's my 3rd sd card, which I got as replacement from the company. I had kinda similar issues with the those 2 cards too. Kingston was working fine. Now I have placed an order for samsung sd card. But I wanna know the reason why it is happening? That wired drive path... Whats is that
I have the same issue on the TW roms. But on CM roms no problems at all..
I have same problem
