Hi All,

I am having one HDD in which RHEL 5 is installed, but its not booting up it showing boot error. i am having my data in that HDD.

To take the backup i have connect HHD of faulty machine to another machine having RHEL 5 as slave disk ( secondery disk).

but when i m going to mount it its showing below error,

[root@localhost test1]# mount -t ext3 /dev/hdc2 /mnt/2hdc/
mount: wrong fs type, bad option, bad superblock on /dev/hdc2,
missing codepage or other error
In some cases useful info is found in syslog - try
dmesg | tail or so

Plz suggest.

I tried with tune2fs command but no luck
its showing below error .

[root@localhost test1]# tune2fs -l /dev/hdc2
tune2fs 1.39 (29-May-2006)
tune2fs: Bad magic number in super-block while trying to open /dev/hdc2
Couldn't find valid filesystem superblock.

can you post the "fdisk -l /dev/hdc2" output

Thanks for Reply.

[root@localhost test1]# fdisk -l /dev/hdc2

Disk /dev/hdc2: 39.8 GB, 39892608000 bytes
16 heads, 63 sectors/track, 77296 cylinders
Units = cylinders of 1008 * 512 = 516096 bytes

Disk /dev/hdc2 doesn't contain a valid partition table

You are trying to access a partition as a block device...

tune2fs and fdisk should operate on the device /dev/hdc not the partition /dev/hdc2

What does dmesg say when you try to mount the device?

#dmesg
hfs: unable to find HFS+ superblock
VFS: Can't find ext3 filesystem on dev hdb.
hfs: unable to find HFS+ superblock

Post the output of the command
fdisk -l /dev/hdc

Is this drive part of a RAID or contain LVM partitions?

[root@myhost ~]# fdisk -l /dev/hdc

Disk /dev/hdc: 8589 MB, 8589934592 bytes
255 heads, 63 sectors/track, 1044 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Disk /dev/hdc doesn't contain a valid partition table
You have new mail in /var/spool/mail/root

from your output it clearly says that it does not contain any partition. After connecting the hard disk, how do you know that the newly attached hard disk device driver is /dev/hdc2. Also please post the output of "fdisk -l" command.
