Hi,

I had a problem with a Quantum XP34300 - it was very noisy.  It was replaced
and I am now not able to mount it.  The boot messages are:

-----------------

When I run e2fsck I get the following:

bash# /sbin/e2fsck -b 8193 /dev/sdb
e2fsck 1.04, 16-May-96 for EXT2 FS 0.5b, 95/08/09
/sbin/e2fsck: Bad magic number in super-block while trying to open /dev/sdb

The filesystem superblock is corrupt.  Try running e2fsck with an alternate
superblock using the -b option.  (8193 is commonly an alternate superblock;
Hence, 'e2fsck -b 8193 <device>' may recover the filesystem.)


--------------------------

I am not very familiar with hardware in general and I don't know what to do to
get this disk to work.

Can someone please help me?
