[SLUG] urgent! Hard disc dissapeared.

[Jeff Ai <jeffaiau@xxxxxxxxxxxx>]

I was doing some recording using audacity, when i tried to save a 
project, the system froze and i could not switch to a console to shut 
the machine down, so i had to use the reset button and after this my 
system could not boot up anymore, it could not a mount the hard disk 
which i mount to /home ... the error message reads

The superblock could not be read or does not describe a correct ext2
filesystem. If the device is valid and it really contains an ext2
filesystem (and not swap of ufs or something else), then the superblock
is currupt, and you might try running e2fsck with an alternate superblock:
e2fsck -b 8193 <device>

then i log into the rescue mode and the /dev/hdb1 is not there. what is 
going on here? googling didn't give me much more information.

i have all my data on this disk and only have a partial backup ... can 
anyone please help me?


thanks a lot
