Hi,
I connected my harddisk as slave and issued "mkfs /dev/hdb2" accidentally.
Immediately I did ctrl C and stopped the process. But before that it had deleted some 100 Blocks.

After that I am unable to boot that hard disk as primary device. The system is asking me "please insert a valid boot device and press enter"

I am even unable to connect it as a slave device and mount it. The mount is saying bad super block information.

mount -t ext3 /dev/hdb2 mnt_pt/
mount: wrong fs type, bad option, bad superblock on /dev/hdb2,
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?)

Please tell me how can I recover my data.

This disk is containing important data.

A hex editor may get you by, that is to maybe recover the info. I have found text is easiest to recover.

Hi,
Thanks for your reply. Can you tell me where can I get the hex editor and how to use it to recover data.

there is an editor called khexedit which comes with kde in kde-utils

also this is not the correct forum to post this query
post it in the newbiew/software/general section to get the proper attention it needs

regards
