this looks similar to a problem i had with lots of bad sectors on the
disk. read time out being the main one in my case...

also i was getting lots of sequential blocks at a time, so i assume that
it was also bad blocks on the disk sector realication tables...

it may pay to build a tomsrtbt disk and do a file system check with bad
block checking enabled.

yours,
