SD Card Corruption - The card or my activity? - Nexus One Q&A, Help & Troubleshooting

I use a Class 6 8GB AData microSD Card, and used it for around a year in my Blackberry Bold 9700 with no problems.
When I purchased my N1, I quickly rooted it and installed CM 5.0.0.53 with a 512MB ext4 partition for my Apps. It worked fine for around 2 weeks, and one day I woke up to a message saying SD Card Corrupted, please format your card. I could still access the card via mounting it to Windows, and was able to back it up (and the ext partition worked fine) but nothing I could do save for formatting the card completely and restoring a nandroid would save the FAT32 partition.
I decided to format again using ext3 this time and install CM 5.0.6, both of which I heard were more reliable. Again, a month later, I have a corrupted FAT32 partition (only on the device, not through mounting) and cannot access any of my data on the device itself.
Is this my activity, or could it be something else? I am at a loss to explain it, since the card seems to be fine in Windows. Is this a CM problem?
Thanks in advance for any insight you may be able to share.

I keep getting damaged SD card error on my phone

On my computer it's fine. I just want to listen to my music. Damaged or not.
What causes Damaged SD cards?
Try to reformat it and see if it works. There are several things that can cause a card to go bad.
I have and just spent countless hours getting music on the card and I downloaded an .apk when I got error (Installed and worked fine) then just got error.
How to safe me from these from happening again?
All my apps are gone due to app2sd bummer

Just do what you always prolly do. Just make sure to unmount before you disconnect. Sometimes the cards can just go bad. Just make sure to get a name brand card and get a class 6 (you don't have to). It was prolly just a fluke.
Sandisk 8gb class 2 I do unmount error for past 3 months. Know I can't get back my apps2sd to rework after I did a format.
How did you format it? In the phone from UI? If so then it erased your ext partition.
Look in HERE for good guide on how to check what partitions do you have and to format and repartition.
Good luck
If your running swapper, you need to turn it off before mounting. Thats the main cause if its not actually damaged.
I had that happen to me when I tried using Apps 2 SD 2. It said it corrupted my SD, and when ever I tried to unmount from the PC, it would freeze up. I just backed it up, deleted all my partitions, reformated and made new ones. What ever A2SD you're using, make sure you follow tuts correctly.
If you use AppsToSD to partition your card and you get an error saying that your SD card is corrupted or damaged, ignore it. Take out the card, format the Fat32 partition on your PC (a full format, not quick erase). When it's done, both the Fat32 and ext2 partitions will be there. I have experienced that problem several times.
Also, you can do adb to get the files off the ext2 partition before you use the phone to remove the partition and re-format the card.
Well guess what all I did was turn off my phone overnight and charge it. This morning turned back on got the same good message after spending 5 hours putting music onto my card. So this time I am doing a full format of the card and just using fat32 nothing more no apps2sd I think that may be my problem. Cause when using it I don't get the option to safe remove the sd card in SD card settings.
My 2-yr old 8gig Sandisk Class 2 SDHC suddenly went kaput and won't be detected by my Topaz.
This sd card has been previously fat32-formatted and worked for 2 yrs.
Lately, before flashing a cooked ROM, I ran the mtty1.42 if that matters
Now, my phone won't even detect another sdhc (4gig Sandisk, Class 6) which is working fine on my wife's Raphael and/or my PC.
The error message the defunct 8gig SD card gives when connected via card reader to my XP sp2 machine is:
Exception Processing Message c0000013
Parameters 75b6bf7c 4 75b6bf7 c 75b6bf7c

You can't format something that is undetected, right? Any clue, please? Thanks.

Yea that happens my 1yr 8Gb class 6 dies a while ago but that was from my using it for readyboost and eboostr(unrelated).Now i got this 4gb class 2 thats pretty fast If you had swapper then i think the card could be damaged, try formatting that sd card in recovery mode.
there is a way to reformat the card if its not physically damaged but it seems like yours is. I dont rmr the commands to do it in gparted, butits possible

Important question pertaining the Cyanogen auto apps2sd

Yesterday I upgraded to cyanogen's 4.0.4, it said that i would have to partition my sd card(8gb) to allow the apps2sd to automatically work, a friend of mines recommended Paragon Partition Manager, i installed it, and partition my sd card, to ext 3 format, so i have about 1.3 gb of partitioned sd card and about a little over 6 gigs for music and videos. The cyanogen FAQs said that " 4. How do I set up apps-to-sd?
You need to create a second partition on your SD card in the ext2/ext3/ext4 format. Search the forums if you don't know how to do this. Once created, the ROM will move your apps automatically and new apps will be installed to the SD by default. " but it hasnt freed up any space on my phone, and when i download new apps, it still goes directly to the phone. Am I doing somthing wrong and should i consider reformating the whole sd card, partioning over again and adding a lower amount for apps and a linux swap partion also.

You aren't meant to make one bigger than 1.5, yours is very close so it could be the issue.
A good way to check if its working is if space is being used up on the ext3. Go to Setting > SD > secondary partition.
Also try rebooting, you might find that your internal space increases afterwards.
If neither of those work then reformat and make a smaller ext partition. I'm struggling to fill up my 500mb, why anyone would need 1GB+ is beyond me.
also,i am noticing since i have done this partitioning, that if i have my sd card in the phone and reboot, that after the android boot screen, that my phone will go blank, and if i pull the card and battery out and reboot with no card in the phone will do fine.

Hold on. Your phone will only boot properly without the sdcard. You should not remove the card when the phone is on, because it can bork your entire partition.
If I was you I'd wipe the card and start over, adding a smaller ext partition.
ahh shoot, ok then, i just formatted the partion back to fat 32, so you suggest me to just, re partition it in ext 3 and make it smaller to about 500 mb should i also make a linux swap?
and also, although i formatted it back to fat 32, it wont let me merge the files back into 7.3 gigs. or maybe i am not doing it right.

merge files? got no idea what you're talking about.
Just wipe all partitions on the card. Make one ~7GB FAT32, ~500mb ext3 and if you want 32mb linux swap. To be safe wipe your phone and reflash cyanogen mod.
yea well, i dont know what is going on with it, but i have wiped, and rebooted, now and it is still blank after the android boot screen, and the sd card is in it now. i dont know what to say now.
i have the same issue
The problem is the Recovery IMG
Try install this recovery image: RA-dream-v1.2.3 Recovery Image
The make the partitions again from the recovery console
Jesus, man...
I suppose because of lingering paranoia from the days of filling my phone up daily, I've always made an Ext partition around a gig. I've never, ever, ever even filled half of it.
Then again, since I don't usually listen to music on my phone I also Have a nearly 7 gig fat 32 partition that I don't often fill. Honestly, it's probably because I keep losing the damned jack adapter and I haven't seen the earbuds I bought with the jack attached in months.
I have so many 3.5mm headphones around and still, those damned adapters elude me.
having a few issues in this area as well, all is partitioned as reccomended within the recovery console, (~7Gigs'ish fat32 and a 500MB part on ext3...) apps to SD is still blanked out... weird from my POV, as it worked fine until i updated to CyanogenMod 5.0.7 test 5..
Can anyone reccomend a more stable "2.1" based Cyan rom? or is the 5.*.* series the first of its kind to utilize 2.1? sorry for veering off-topic, but i feel my problem may be the newest releas of CM as it IS a test build...
Any words of wisdom would be greaaaaatly appreciated. not new to this stuff, but the apps2sd thing i never bothered with untill now (i do so mu h reformatting and build testing its becoming a pain to re-install all my apps... as i refuse to pay for the MyBackup app lol)

Big problems with CyanogenMod-4.2.11.1 and APPS2SD

Hi
I have some big problems when I use an EXT2, EXT3 ore EXT4 partition on my SD card.
I want to use APPS2SD to save memory space, but as soon as I make an EXT partition on my SD card, my phone always hangs all the time in the startup.
I get the Android logo, and that the screen goes black with background light, and hangs like that fore 30min with no change.
But if I eject my SD card and start up without it, it's no problem, but now all my programs are in the SD card so they are missing.
What I've done:
I had CyanogenMod-4.2.05.
Made an EXT3 partiotion on my SD card.
Made an linux-swap 31mb partiotion
Updatet to CyanogenMod-4.2.11.1 and than it started up, added my progs to the SD.
Had 1 reboot with no problem, tried to update some programs, than it hang up on the update, woudnt update.
So I had an reboot, that when it started up I got a lot of error messages on the updates.
Tried an new update, and now it wont start up with the SD inserted.
I tried ext partition on my erlier CyanogenMod but same problem than also...
What could my problem be?
Have an 8gb class 4 micro SD card
when I now trie to install programs I get an error message "Insuffcient storage availble"
Clearly this is a problem with your sdcard. Try complete re-format first, followed by complete wipe and re-flash. If that doesn't help then you need a new sdcard.
Good luck.
In what order are your partitions? It sounds like you no longer have the FAT32 as mmcblk0p1? Make sure the first partition is the FAT32, the second is EXT, and the third your swap.
Hi
Could be my card, it's an ebay card so, but works fine with music...
I use an guide fore formating my card, and I make the fat32 first, than ext and so the swap.
Now I tried to make an partition with ubuntu, and without the swap, but dosent seem to help, black screen after the adroid logo....
I guess I give up and its my card...
When i use the Print comand in parted i get the fat32 up first...
Print
number start end size type file system fla
gs
1 0 7500 7500mb primary fat32 lba
2 7500 8000 500mb primary ext2
3 8000 8032 32mb primary linux-swap(v1)
Use AmonRa's recovery? It will paritition the card for you the right way with whatever size partitions you specify.
Ok so my partition could be the problem?
ill try the AmonRa's recovery than, and if not I guess its not ment to be apps2sd on my phone...
Well, I wouldn't say that apps2sd is not ment for your phone since so many of us are using this hack (including myself) however this may be a tedious process of eliminating possible causes. I would not rule out the possibility of damaged SD card. It has happened before to many people. Re-format and re-partition your existing card first. Wipe everything off your phone, re-flash the rom of your choice (following the instructions) and see if it works. If it doesn't work - then I would look into getting a different SD card. I just received a tweet that compUSA has class 6 8GbB card with adapter for $30. I also saw something in "Dream accessories" forum in the "Promotions" thread, I believe 8GB card for $15 from Amazon. Cards are a lot cheaper then new phone, you should try that out. Good luck.
Ok.
I've now installed the AmonRa's recovery 1.5.2
Partition the card with AmonRa's recovery
Wiped data/factory
Shud I wipe dalvik-cache, battry status, and rotate settings also?
Wipe dalvik-cache, others should not matter for what you're trying to accomplish.
Ok thx.
I'll try that, if it doesnt work now, I'll buy an new sd card
So AmonRa's recovery didnt help, so I guess it's my sd card than.
Will buy an new one and test with that.
So fore now on it's low on space
Maby this time I will remember to take an backup when I have y phone the way I like, getting tierd of setting up my phone all the time

Can't Format SD Card

I lost my sd card data flashing a rom. Could not mount it even thru recovery. Got a card reader, but it won't format it.
Using Mini Partition Tool to troubleshoot. I am not at a point where it shows three partitions. The main 16gb unallocated, logical. The ext3 unformatted 500mb, primary (think I did that by mistake when trying to recover partition). And a 32mb unallocated, logical. All zero used memory.
I need to get back to one partition allocated, primary. Then I can get sd data back on it and reformat thru recovery.
Again using Mini Partition Wizard
Any help please!
OK,
I got it repartitioned as primary and formatted, bu sd card from pc now.
Hope phone recognizes it.
Will update, if I need further help.
Ken
If you want a good program to format your sd card, try SD Formatter.
Download and install that, plug in your sdcard into your sd card reader and format it.
Choose Full Erase On (if possible) and Resize On. It will format your sdcard to factory default and that means even the ext partition will be gone too.
Well, all transferred. Still won't mount. Says can't mount either of the dev/blocks mmcb1k0p1 and mmcb1k0.
Staus bar says sd card damaged.
?????
musashiken,
Thanks, typing while you posted. Based on my last post should I still do that?
Ken
Yeah I think you should try to reformat again with the program I suggested, as that will full format your sd card.
Once done, put your sd card back to the phone and create ext partition in recovery.
At work now but will be working on it.
Thanks
Ken
musashiken,
Thanks, appreciate all your help
That program worked, and I am back up and running
Ken
Glad it worked for you. My sd card kept giving me problems and I have to use this every few rom flashes.
I have a similar problem. I installed a new 32 gb SDHC card in a CDMA Hero running Cryogenmod. All was working well for about 10 days, then I got an error that no SD card was found. I had the original card and tried to get to the Clockwork recovery, no luck. Finally, through Rom manager, (flash alternate recovery to Ramon, then back to Clockwork, I was able to boot into recovery.
I still cannot format the new SDHC card, through Recovery, Windows 7, or the Panasonic program listed above. The Windows format option sees the card as a FAT 121mb card, so does the above program. Is this new card toast? It came with a lifetime warranty from Kingston, but I am mad that it did not make 2 weeks.
Any help would be greatly appreciated.
Craig
If sdformatter did not work it may be bad.
I always had good luck with it.
Did you have all options set per instructions?

[Q] Link2Sd Right partition combination and slow sd card

Hi guys
I'm looking forward to use Link2sd so I installed minitoll partition wizard and tried to create 2 partitions:
1 Primary 7 Gb FAT32
1 Primary 0.6 Gb Ext2
i could never complete the task and partition wizard kept saying the sd card was unformatted. I found on anther thread that for some phones Ext2 partition did not work and that a second Fat32 could solve the issue.
I went down that road and the sd formatting went fine creating 2 Fat32 partition.
The BIG problem is that the sd card (Kingston 8 Gb class4) is extremely slow, getting all my backuo data back into it took like 30 hours.
Is this normal ?
What is the proper partition combination for the X8 on order to use Link2sd ??
Such slow writing speed to the sdcard seems a pretty high price to pay...is it worth ???

I used the same software to create partition in my Sandisc 8GB class2 SD card. It took around 10 mins to create and format the card with 7.5GB FAT32 and 0.5GB Ext2. Both are primary.
I suggest you to check the Card and software by interchanging them. That is try with same software on a new computer with this card and again on your machine try a new or another card.
Another way that you can make the partition in CWM recovery.
Positively there is something wrong, the time you mentioned is too unusual.
Hi
Thanks a lot, when you are so close to the trees you can't see the forest.jaja
After several combinations I realized that the sd card port on the laptop was defective. I used an usb adapter and partioned with minitools, just as you said and worked...finally.
Cheers
