So, the disk itself, how bad is it?  Unknown?  You can try e2fsck -n
to see just how many there are going to be and also perhaps play with
-c to fiddle with badblocks.  But at the end of the day (baring
expensive stuff), you're going to have some holes in your data,
somewhere.  Or at least that's my recollection + quick googling.
