SD Card Corruption with Nexus One (has happened twice)

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.

Xperia TL - SD Card Removed, though I never did that!

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.

Micro sdcard phantom wiped/erased

What a nightmare! I grabbed my Tab S 10.5 this morning and the stupid thing was showing there was nothing on my sdcard at all! All my apps that used it are now complaining and have no data at all. What a nightmare. The most annoying thing is that it's a Samsung branded micro sdcard to boot. Come on man!!! Some top of the line tablet this is!
Update:
Well, I pulled the micro sdcard out of the Tab S and put it in my PC and the data is still on it. So, the Tab S is apparently just not reading it. The only thing I can think of is backing it up on my PC and putting it back in the Tablet and reformatting it, then putting it back in the PC to restore the data. WASTE OF TIME for a so called Top of the Line Tab from Samsung!
Update 2:
Well, I put it back in the Tab S and it still wasn't reading it. So, I went to Settings/General/Storage and selected 'Unmount SD card'. Then I pulled it and put it back in the Tab S and it is now reading the thing. I imagine that's the trick if the micro sdcard is showing nothing on it all of a sudden. Strange behavior for a top of the line tablet...Anyway, problem averted...

Is it still working for you? I ask as I had the same issue with a Tab S 8.4 and a Samsung EVO 64GB card, and tried your solution several times, but it did no good whatsoever. After a week or so I gave up and put in an old Sandisk 16GB card and it has worked flawlessly. However, it is full and I could do with the space of the 64GB card.

I have the same issue with my Tab S 10.5. I have a 32 Gig Sandisk Ultra and it randomly does the same thing where it shows no data. The fix for me is to just reboot my tablet and it usually works for a few days but it is a repeating problem for me. I agree this is very frustrating to have a flagship device that has such issues with SD cards. FYI I have used that card in several other devices with no issues what so ever. I am holding out hope that a software update may fix the issue? Maybe Lollipop?

Nope. It finally just completely died. I'm using a Sandisk now.

Running blisspop by chance? I had that prob fixed in 2.0. You can also fix it with terminal emulator.

Data is getting automatically lost from memory card. Reasons??

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

SD card read failure

Every so often I get an error saying the sd card is corrupt or not working or something, and photos or music on the card will not open. After a hard reset, it works fine. Is this common? The card is basically brand new but I suppose it could be that.

So I am having a lot of things acting weird. Apps not working, sd card failure... I need to do a hard reset about once a day now. It is becoming a little frustrating. Any suggestions?

So I opened up the sd and sim tray, took out the cards and put them back in. Seemed to fix the problem for a number of days. This morning I had the failure again and I opened the tray and I noticed that the SD was a little off... does anyone else have this problem? Of the card moving around? Any idea how to fix it?
I may just have a bad sd card, now that I think about it.

Thank you because now i know i am not the only one with this problem!

Hey actually I got a new sd card and it has ZERO problems now. Taking the card in and out was only a temperary fix. i think the real problem was a bad chip. I had the PNY 128gb one ($30) and now I am using the SanDisk 128gb one ($40). I would only buy SanDisk from now on.

Unlucky many people have the same problem and no, your sd card is good... there is something wrong with the hardware or software of the huwawei..

I'm having the same problem with my Huawei P9 lite, both the phone and the SD card Kingston32GB are new, i even bought another SD card because i thought the first one was bad, but the problem persist. I haven't found a solution yet.

I have the same problem. I do not think it is specific to the card. I think the card is dislodged and moves around in the card tray and thus gives the issues.
I wanted to but a new card as well, but think this will not solve the issues. I will try sticking the card in the slot somehow to see if that solves things....

I've had my P9 Lite for a month now, and I've only started getting the SD Card corrupt error since last night. Unmounting, and mounting it again fixed it briefly, but then I got the error again while trying to take a photo about an hour ago. I've just formatted the SD card to see if it will fix the problem. I'm hoping for the best.
Have any of you fixed the issue successfully?

I get this when I copy a large files to the microSD card, movies for example (1080P FLAC 4GB each or something). It still works fine though.

Just an update: My SD card gave in completely last night! :crying: It worked fine after formatting, without any errors, until it just stopped working, so I lost a few days of pictures. Anyway, the SD card isn't even being read in my laptop, so it's definitely a goner. I'm currently using a different memory card, to make sure that the same doesn't happen to that one, to make sure it's not my device corrupting the cards.

Sounds a lot like my issues.
After having the phone P9 lite for about half a year, i'm on my second sd card.
2 weeks ago, i had the message it was bad once or twice, but now my phone is acting weird. A few apps (Twitter, netflix, pokemon go) will just start and close instantly sometimes. Apps will just crash. And everytime i reboot my phone, all that has happened after the 6th of July is nowhere to be found on my SD card.
It took me a few days to realize I might have some problems.
But reading this thread i might invest in a new sd card before doing a factory reset.

Problem is from bad quality sd card not from the phone,exactly like u are connect usb flash to your computer,if sometimes u have problem with the usb flash ,u should blame the usb flash not your computer.your phone is just a reader,try to buy good quality sd card

Did the same thing happen to your first SD card? I actually only started getting the issue when I updated to Nougat. I noticed that when I reboot my phone, just before it switches off, I see the notification that the SD card was removed abruptly, so I think it could have something to do with the software that doesn't safely eject the SD card before the device restarts or shuts down. I might be wrong though, but it's just a theory. I don't restart my device too often, but when I sometimes insert my SD card into my card reader, I get a prompt to say my SD has errors, and needs to be scanned.

I had a Kingston one, something i consider good quality.
But you make a valid point and i'm currently looking around for a new one.
It seems that for now my problems are solved by an old one i had lying around.
Saw SanDisk being promoted.

No, it behaved quite differently. That escalated from one of two error messages in a week to multiple errors daily.
And it was really corrupted, couldn't format it on the pc or anything.
But how is your current card behaving? All is well?

I had a 32GB (Class 4) Kingston SD card as well, which is one of the brands Huawei recommends to do software updates with. I had that card for 4 years, if I remember correctly, and I've used it with 3 devices, including my P9 Lite, which was the only device it gave problems in (only after updating to Nougat).
At the moment it's still behaving. I got a 32GB Class 10 Sandisk a week or two after my previous post, and so far it's fine. Like I said earlier, when I put my SD card into my card reader, I get an error message to scan my SD card, which means my device doesn't eject my card correctly, before rebooting. I still believe it is either an issue with Nougat, or EMUI 5.0. Again, this is my theory, according to my personal experience.

For me the problem also seems to be solved in the mean time with a new sd card.
Don't know if i like your theory though, since it would mean it is just a matter of time.
On the other hand, google does not show that many complaints......
Time will tell I guess.

I don't like my theory either, lol, but today when I was taking photos, I tried viewing the photos within the camera app, but it took a while to load them, and my gallery app stopped responding. I'm hoping it doesn't have anything to do with the SD card though, but I can't help being sceptical.

I changed from Samsung to Sandisk, yesterday after os update same thing. Took out the card, apps default to internal storage and works. Reseller is no help say it's virus. I am sorry I gave up my Samsung edge. May be should have bought iPhone if only working wit internal storage.

I have an expensive SanDisk card and it's worked fine for over a year, just started happening to me too now though...
