Re: [gentoo-user] failed reiserfs partition - help!

[James <jtp@nc.rr.com>]

Sorry -- it's a USB device so the drive letter has changed as I've
moved the drive around.

My friend threw a theory out there -- maybe the beginning of the
partition is incorrect on the drive? The drive originally had an NTFS
partition. By blowing away the beginning of the drive and then
rewriting the partition table, maybe the kernel was using the original
"beginning" location of the NTFS partition which *may* be incorrect
for the beginning of the reiserfs /dev/sdX1 partition. I did *NOT*
reboot after making changes to the partition table (nor did I
disconnect / reconnect the drive).

Is this possible?

I'm 99.99999% sure this drive is not defective. There has to be some
way to mount this partition as it was cleanly unmounted and the data
copied over with no issues when I was originally doing it.

Isn't there a way to search for a superblock on the drive and then use
that when attempting to mount the partition?
