Fsck.vfat Fails On Hard Drive

[daniel3000]

Hi guys,

on my SL-C3200 with a 3GB third partition (FAT 32), fsck.vfat fails:

Code: [Select]

root@˜>fsck.vfat /dev/hda3
disfsck 2.11, 12 Mar 2005, FAT32, LFN
Seek to -1279934976:Invalid argument

Does anyone know this symptom?
I have observed it on three different SL-C3200 with slightly different partitioning (hda3 sizes 3GB and 4GB)
fsck.vfat works fine on flash cards.

Thanks
daniel

i suspect this is an issue with fat only supporting a max of 2GB and fsck.vfat only supporting that.
i cant fsck my 4GB SD while I can fsck my 1GB SD both formatted with FAT

do you have any experiences if it is safe to check the FAT partition of the hard drive via USB (USB storage client) from a Windows PC?

I have used fsck.vfat /dev/hda3 on my C3100 running Cacko several times.
My partition is 3.8GB (Default Sharp/Cacko partition)
My only complaint about this is, It only works in emergency mode, using the D+B option.
I think I get a similar error as daneil3000 if NOT using emergency console.
A year and several months ago I when I first got my C3100, I was having a problem with a file that "seemed" like it wasn't completely deleted.
Someone that knew what they were talking about, told me to use this after starting emergency mode with the D+B option.

To do a file system check on /hdd3 use below command:
If you boot with the B+D option, login as root and use
fsck.vfat -a -f -t -v -V /dev/hda3

This has worked for me every time.
It does take about an hour or more to finish.
It does warn that FAT32 support is ALPHA

BTW, checking a drive or defragging a drive over USB in Windows is very slow. I don't recommend this.

is it possible to cross-build a newer fat32 kernel module  and a new fsck.vfat command and use that instead?
