I had a 2 GB (Scandisk) micro SD card in the beggining when i got my Kaiser. my phone was slow (even with programs installed on the device) but i didnt realise how slow it was until I put another micro SD card (Kingston).
My other card fried thats why I changed it.
With my new SDcard my phone works fast. I have half of my programs on the card and other media and it works great.
So maybe if anyone suffers from slow processing, a solution could be back up your stuff and get a new SDcard or Format your existing one.
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.
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!

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.
Guys my phone fell down from a very short height and the sd card was removed unexpectedly & from then on my SD card is no getting recognized properly i formatted it in different formats and stuff but doesnt work properly it gets recognized sometimes but after a while it doesnt .

My Card sd also started well , stopped recognizing of nowhere, did a master reset on the phone and he returned to work , he spent three months and was to waste :/ 32GB :crying::crying::crying::crying:
SD Cards spoil the use of writing and reading ...
In computer also read and read everything less in the Smartphone , I'm sure this may indicate that very soon he will die just like my , when he dies once he stops working on all devices .
My smartphone did not fall or anything, the card only stopped from scratch.
angry bought a 32GB Class 10.
Seems it's not uncommon problem, Moto od mine has it too. Regardless od SD Card (32 GB Sandisk, couple od 16 GB Kingstones, 8 GB Sony) it says Card is empty and offers me formatting, while all cards work just fine with my other devices (Lenovo Yoga 2, Samsung Galaxy tab 4 or Lumia 640). Moto is completely stock 5.0.2 factory ROM, not rooted, untouched bootloader. Any help?
