Anyone else have this problem? I've had this "issue" since I've gotten my AT&T Nexus One.
I have a class 4 microSD 8gig card, filled with about 4gigs of stuff.
AT&T Nexus One, currently running FRF85B (but "issue" was present in 54b, frf50, frf72, frf83)
Whenever I turn on my Nexus One it takes about 5 minutes for it to "scanning card for errors".
N/M I had a wep cracking app, that required a download of a rainbow dictionary, and that was 21 megs, but had over 8,000 files.
That slowed down the "preparing sd card" significantly.
what app was that?

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.
I am a newbie, still on original nook firmware think its 1.01
I am having trouble trying to install cm7 on a 16gb microsd card. I had a look in XDA and there are a few people having the same problems awhile ago, and then there are some who have managed to do it. I have trawled thru quite a few pages int he foru but can't seem to find a solution. Anyone here has any luck with installing cm7 to boot from a 16gb microsd? Any comments would be appreciated.
My problem seem to be, after i imaged the microsd and then copied the update night;y cm7. zip file across, the nook booth from the microsd but and setsups but then just hangs after superfiles(?) have been installed, whereas the guide saystehat it will ventually go to a blanks screen, which mine never does, then when i force shuitdown and reboot, it installls some android files but when it reboots after that it either hangs onthe ANDROID_ screen (keeps rebooting over and over again) or it goes to the cyogenm7 graphic screen and keeps rebooting to the startup screen.
Thanks
Try a different SD card, preferably 8G or less. Quite a few cards don't play nice. If you can get CM7 installed on a different card but still want to try it on your 16G card, you can image it over from your other working card. You'd then need to expand the 4th partition to reclaim the space then. It may work, or you may get random quirkiness using that card with force closes here and there.
I'd make sure to get a genuine SD card from a reputable dealer, not some dodgy one off Ebay. I have found Sandisk to be very reliable, and generally a cheaper Class 2 or 4 card will work better due to higher speeds with small random block r/w.
Good luck.
Hi there! I've been using CM7 for a while now and have had three or four occasions so far where my 16 Gig Patriot Class 10 card has ended up with either partially or completely corrupted data and I'm curious if this is just an issue with a cheap card, some feature of the Nook or related to something in CM7. Most of the time it will eventually come up with a damaged SD card warning but prior to that my directory structure gets mutated into symbols instead of letters (it's current state).
I'm planning on swapping out the card with a SanDisk I have here so if it's the card I suspect the problem will go away but mostly I was wondering:
1. Anyone else have this issue?
2. Are there any known fixes?
Appreciate any help. Would eventually like to be able to use this card for storing movies but having it fritz out from time to time is a real pain with the amount of stuff android keeps on the SD cards.
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 everyone,
I've had my Note 4 for a few weeks now and I love it. I haven't rooted it yet and gonna wait for Android 5 before I do. Still, I've ran into a couple of annoying issues. Not gonna worry about the minor ones, cause they may disappear when 5.0 comes out.
The main issue though, is that the SD card seems to randomly unmount and mount for some unknown reason. The weird thing is, I can still access everything on the memory card, however, my Play Music player no longer recognizes the music on the card, unless I disable the app and re-enable it.
Strangely enough, I can open and play a song directly going through "my files" but Play Music doesn't seem to see them after the card randomly unmounted and mounted itself.
Anyone else having this issue? Any advice? It's a sandisk class 10 64GB, about 20GB free. Was in my Galaxy Note 2 prior to moving it over to the 4.
There have been threads about this issue. I think the Note 4 doesn't like SanDisk brand cards because it seems the issues have always been with this brand. Just get a new Samsung brand one. I too have this issue and the card worked perfectly for years on the Note 2 prior to this.
I can't say i have this issue and I have sandisk 32...been using it since my g3 days
Mgbotoe it will happen eventually, esp of you ever try their bigger cards. SanDisk is the "yugo" brand of memory.

I have read that there was a problem with some versions of the Sandisk card. In the reviews on Amazon people were saying that Sandisk replaced their card with the newer version because of the unmounting issue.
I had this issue with sandisk too. I'm using my 3y/o sandisk class 4 64gb right now and its not giving me issues, but the newer class 10 64gb I bought last year had to be replaced once and it recently crapped out again. Not even bothering to RMA it this time, I'm just gonna get a Samsung soon.

Backup the card immediately and order a replacement. I had a Kingston card fail entirely (not recoverable, wouldn't even mount) soon after it started exhibiting this behavior.
It's strange that it only seems to effect my Google play music app. I've backed up this card as you guys recommended. I'll try to pick something up on black friday. Looks like Samsung doesn't have a 128GB yet.
