[rhn-users] Question for how to fix disk corruption

[Yasushi Okubo]

I had an ext3 hard disk in /dev/hdc, but now its partition looks strange 
[it became empty, but actually not].   So, I ran e2fsck, but could not 
find any bad blocks.    Could someone advise me how to restore parition 
table  ?   I would like to recover 8273 regular files stored on this disk.
Should I run sfdisk -b ..... ?

Thanks,
yasushi

Warning: no primary partition is marked bootable (active)
This does not matter for LILO, but the DOS MBR will not boot this disk.
