"Boot sector" problem


Hello,

I have this message twice every boottime (don't remember exactly):
"There are differences between boot sector and its backup
Not automatically fixing this
Differences (offset: original/backup) :
...."

I have 2 hard drives
I use Debian, kernel : 2.6.1



Other question : Does a line in etc/fstab that have the option "noauto" can print an error "wrong fs type" during boot time?

Thanx!

1st Q: I'd suggest you re-install your GRUB / LILO since this overwrites the boot-sector and thus should produce any necessary backup (Reason: since you obviously can boot now, there is some risk that the backup is corrupted and thus you should ensure correct backup...)

2nd Q: You can get this error for sure, but it has got nothing to do with "noauto" (only with the file system type you try to mount). Make sure of the file system type on the device you try to mount to your mount point, e.g. with "fdisk".
Code:
man mount
man fstab
man fdisk 
    alternatively use the help menu of fdisk (just start it...)

Thanx but i've still these problems

1) Well i have run "lilo" (to reinstall lilo), nothing changed. I noticed that the so-called "backup" of boot sector was in a file called "boot.NNNN" in /boot/. Yes there is a file /boot/boot.0300 . I saw that "lilo -s file" could make this backup. So i did "lilo -s /boot/boot.0300" (after having renamed the old boot.0300). But nothing changed neither. Maybe the number NNNN is false...

2) I think the problem comes from my 3 FAT partitions because i have 3 "Wrong fs type ..." errors during boot.
Code:
/dev/hda5       /mnt/fatidik    vfat    uid=1000,gid=1000,rw    0       2
/dev/hdb5       /mnt/fatima     vfat    uid=1000,gid=1000,rw    0       2
/dev/hdb1       /mnt/fatality   vfat    uid=1000,gid=1000,rw,noauto     0       2
I tried "fat" instead of "vfat", it shown me "mount: fs type fat not supported by kernel"

Dunno what lilo is doing here, I usually do my backup of the bootsector with dd and else use GRUB, sorry no more ideas here...

Use fdisk to check the true type of file system of your partitions and edit fstab accordingly. "fat" is not used as keyword by mount.

Sorry for the late answer, I was on a vacation...
