memory card corrupted (MicroSD)
 
a few days ago i noticed i couldn't access the micro sd card in my N900. it worked perfectly before and it still works perfectly when i use it on my pc or other phones. i even can format it on my pc without problems.

but everytime i put it i my N900 it gives a message in the "memory" page in settings that the card is corrupted.

i installed the 900MHz zImage kernel could that be a problem?

Try backing up the data on your PC, reformatting the microsd card and putting the data back. If you still have problems it's not the card itself.

As root in terminal:
fsck.vfat -a /dev/mmcblk1p1
then reboot

i've already tried that

this gives me
open /dev/mmcblk1p1:No such file or directory
and no, i didn't type it wrong, i've copied pasted it

but in /dev
i have a few directories with the same naming;
mmcblk0
mmcblk0p1
mmcblk0p2
mmcblk0p3
mmcblk1

edit:

does the p1 mean the partition?
because that'll mean that i have to select the whole device instead of 1 partition. can anyone confirm this?

Could simply be a bad card, I have a 8gb Transcend MicroSD card that is crap, it "works" but everything always becomes corrupt. No matter if I use in my N900, N95, Camera, PC... it is just defective. Other cards work fine.

If you have data you want to recover, try "testdisk", it was able to get most of my files from the corrupt card.

Yes, overclocking the CPU could result in filesystem corruption or even possibly damage to other circuits such as the card reader.

What's the card formatted in?
You can try mount /dev/mmcblk1 /media/mmc1 but I'm not sure if it'd work.

this gives an input/output error :confused:

edit:
is there perhaps a program like fdisk that runs on the N900? because i'm used of using fdisk on linux.

Re: memory card corrupted (MicroSD)
