I tried putting it in the freezer, but that didn't help. Tests on
another computer also show that the hard drive cannot be accessed.

It seems like the data on the disk is definitely lost. The disk,
however, has a 3 year warranty, so I'm going to return it.

Thanks for your help.

I am having trouble with the XFS filesystem on a 320GB Western Digital

Looks like your disk is dying or dead from your logs. You can try putting it
in a plastic airtight bag then put it in the freezer and try again but
otherwise if that does not work, its time for the trash bin (after you try)
a dd and overwrite the disk but with that many bad sectors it looks like
it has really gone south.

Insert new disk, restore from backup.
