ext2 doesn't mount

[Rivendell]

Hallo Everyone

I have a problem with mounting partition with ext2 fs on additional drive.
I have 3 disks all are IDE disks :
hda (hda1 vfat, hda2 ext2 /), hdc1, hdd (hdd1 vfat, hdd2 ext3, hdd4 vfat, hdd5 ext2)

when I try to mount hdd5 when running knoppix from cd it is ok, but when I added line to fstab autogenerated by knoppix it doesn't work
I get a message like this:
mount: wrong fs type, bad option, bad superblock on /dev/hdd5,
or too many mounted file systems
(could this be the IDE device where you in fact use
ide-scsi so that sr0 or sda or so is needed?)

I added line to fstab like this (autogenerated works when running from cd)
/dev/hdd5 /mnt/hdd5 ext2 noauto,users,exec 0 0
but it doesn't work

this is an output from dmesg

hdd5: bad access: block=2, count=2
end_request: I/O error, dev 16:45 (hdd), sector 2
EXT2-fs: unable to read superblock
hdd5: bad access: block=2, count=2
end_request: I/O error, dev 16:45 (hdd), sector 2
EXT2-fs: unable to read superblock

Can it be something with kernel? I compiled a new one maybe something is not enabled, but I don't know what.

thanks for interest.

do a

dmesg|grep hd
folow that with a

dmesg|grep sd
post utput here.
it would also be nice to see your entire fstab. there might be a clue there

from dmesg|grep hd

what does fdisk -l say?
it seems weirdly partitioned, normally you have 3 primary and 1extended, then further partitions IN that extended. OR 4 primary partitions.
that should work in your case. the 4 partitions, that is if you are willing to repartition the drive (wiping data if anythng is stored in that extended partition).

Wow quite interesting, isn't it? however, the most weird is fact that when I run knoppix from cd this partition works excellent!

[OErjan]

copy the /etc/fstab from knoppix onto a floppy and post that here then. and fdisk -l in knoppix aswell please. something is not quite right. your disk seems to be broken oe have a bad partition table (i have seen similar erors caused by partition magic messing up)

[Rivendell]

OK. I've found out that this error is about kernel. I noticed that on default knoppix kernel /dev/hdd5 mounts as well as /dev/hdd6 (swap). Both are extended partitions so I thik than my new kernel doesn't support extended partitions or something like that. I will try to recompile kernel, maybe I will find this option :)

Great thanks for interest.
