Memory problems n900 (Read Only file)

Hello.

* My memory has been corrupted. I do not to format want it.
Has many bad sectors
Deterioration mmcblk0p2:(
The only way to re-partition my drive.
Is there a way to replace the partition?

Re: Memory problems n900 (Read Only file)

You should not need to repartition just yet - check the file system. There are quite a few threads on TMO and possibly some mention in the Wiki. Essentially, you first "unmount" mmcblk0p2 (i.e. the MyDocs partition), then you perform the check and lastly turn the phone off. When you turn it back on, it will all be OK.

Look it up because it's worth remembering the command terms - there are only two or three and they're quite short.

Re: Memory problems n900 (Read Only file)

Try these commands:

Code:

root

umount /dev/mmcblk0p2

fsck.vfat -aw /dev/mmcblk0p2

Yes, that's the actual code for the pseudo code I wrote above. The fsck line needs to be repeated until no errors are reported.

mmcblk0p2 is actually optfs and you cant unmount it while device is on.
MyDocs is mmcblk0p1
and mmcblk0p3 is swap memory

Pm sent.
Try backupmenu and gparted from GParted-Live-CD or ubuntu- / debian-based Live-CD, please.

But I could not run the GParted-Live-CD:(
More help restart and the new partition

Thanks:rolleyes:

fsck.vfat wont run on mmcblk0p2 since its mounted and its ext3 file system.

root
fsck.ext3 /dev/mmcblk0p2

it will ask permission to check as optfs is mounted and you cant unmount it while device is on.

Alternative if you can install backupmenu.
It can check at boot time.

Re: Memory problems n900 (Read Only file)

You're right. I didn't notice it :)

Re: Memory problems n900 (Read Only file)

Either use pali recovery console or backup menu root console
gain root access
then type
fsck.ext3 -f /dev/mmcblk0p2
this will repair all coming errors

Re: Memory problems n900 (Read Only file)

you say you have many bad sectors, so have you tried scanning for bad sectors on a windows pc? (scan and fix)
