Repair a filesystem ...fsck is it???????

Hello People

OK basically I need to know how to fix a linux filesystem? I have loaded SuSe on my laptop and everythime I run the grub setup commands I get filesystem unknown.

The reason for this is that I keep on getting an error 17: cannot mount selected partition.

What I need to do is run some sort of fsck on the partition so that it can repair the filesystem and as I thnk it may have lost some of its superblocks on the partition.

The filesystem was loaded as ext2 .......i think. but when I run root on the grub command line I get unknow filesystem even if I select the correct partition.

I also have redhat and winXP running Fine although redhat has some iptables issue and keeps on asking at boot up to run the iptables -h command

error message goes something like this

......mounting fs vfat ....[failed]
perhaps your kernal needs updating

this occurs on the redhat boot up.

persario 2500 laptop

winxp first partition
linux redhat hda5
suse hda6
swap hda7
vfat hda8

If anybody can shed any light on these issues I would be most grateful.

Thanks in advance.

What is in /dev/hda8 that GRUB needs to know about? If Linux and that other OS run well, it does not seem like a booting issue. I suspect it is a mounting problem. Please list /etc/fstab and the partition table and your filesystem types:
cat /etc/fstab
fdisk -l /dev/hda

cat /proc/filesystems

hda8 is vfat

filesystems does not show vfat


kernel 2.6.5 can be downloaded from

What version of the kernel are you using? If you rolled your own, perhaps you left out vfat support.

An alternative would be to delete the feference to /dev/hda8 in /etc/fstab
