mount problem
hi all
i'm trying 2 mount fs by live cd 2 recover my friend linux box root password
,,,,,
fsdisk -l
/dev/hda1 * 1 35 16506 83 Linux
/dev/hda2 36 13328 6280942+ 5 Extended
/dev/hda5 36 2255 1048918+ 82 Linux swap / Solaris
/dev/hda6 2256 3773 717223+ 83 Linux
/dev/hda7 3774 4857 512158+ 83 Linux
/dev/hda8 4858 12894 3797451 83 Linux
/dev/hda9 12895 13328 205033+ 83 Linux
so now try mount linux part
>mount /dev/hda2 /tmp/hd
SQUASHFS error: Can't find a SQUASHFS superblocks on hda2
FAT : bogus number of reserved sectors
mount : you must specify the filesystem type
what was that error ? filesystem ? is it Ext2 ?

how i can determine that file system ?
You can't?
Ask your friend if he remeber what was files system chosen during Linux setup.
What Linux distribution is installed on that PC? It might help us to determine
file system used.

i can't reach to my friend 2 ask him but it is Redhat and as default Ext2 is file system right !

You may wish to play a little bit with guessing what file system type(s) are partitions you want to mount.
crete firs mount point within /mnt directory
for example :
cd /mnt
mkdir rescue
mount /dev/hda3 /mnt/rescue ext3 defaults 0 0
or
mount /dev/hda3 /mnt/rescue ext2 defaults 0 0
or
mount /dev/hda3 /mnt/rescue reiserfs defaults 0 0
and so on...

Correct , but it could be ext3 too

ok from fdisk list which directory linux installed or to be more specific the redhat files ?
Now that's gonna be the tricky part.
My guess is that /dev/hda1 is most likely /boot prtition and you don't need that one.
You acctually need only read/write access to /etc directory which is usually within /
(system root directory) of the Linux file system.
It is most likely /dev/hda8 according to the number of sectors alocated to that partition.
/dev/hda6 looks like /tmp
and
/dev/hda7 might be /var partition
but also largest one
/dev/hda8 may be /home partiton
Anyway you have to examine all partitons - one at time!

Can you post your /etc/fstab file contens here :
Navigate to your Live CD /etc direcory and type :
cat /etc/fstab
copy and paste its contens .
You have to edit that file in order to create MOUNT POINT where you're going
to mount partitions . If there's no mount point defined your mount will fail.
Also copy and paste dmesg | tail log here.

From your system log outputs I can see you are using SystemRescueCd.
If so, try then to use either GParted (Partition Magic clone for Linux)
or GNU Parted which is the best text tool for editing your disk partitions under linux
to retreive exact informations on what file system types are all those hard-disk
partitions.
Take notes on paper and exit programs . Be very carefull when using partition editors
DO NOT MAKE CHANGES - JUST READ DISK PARTITIONS INFO !!!.

I,m sorry to hear that.
Anyway, You shoud still be able to rescue files from that hard-disk.
But this time,please, use Knoppix Live CD which will automatically mount all
readable partitions so you can see and rescue personal files to , for example USB flash drive .
Or you can use Gparted Live CD and copy entire partitions to other locations.
If you , as you said issued mkfs command it is executed only on one partition,
so most likely other partitions are intact and in good shape.

TRUSTED BY
/dev/hda2 as an EXTENDED PARTITION.
You should be able to mount other partition though.
Firts thing you should know EXACTLY is what kind of
file systems they are ( ext2, ext3, reiserfs, XFS and such )
