what happens if you do: (after you made a backup!) "dd if=/dev/sdX(where X is your affected hdd?) of=/dev/null bs=1" Note: The important bit is the small bs (blocksize) number. You can throw in a O_DIRECT flag to disable the caches, or if you have some "empty" partition space, you can "dd" into it with a small blocksize too)
my seagate & even a samsung hd103uj doesn't like that and will spew out the same sort problems you have just posted... (but they work fine, if I don't do nasty dd things!)
and unfortunatly my md(raid1) seems to do lots of "small" reads & writes when it starts to check/resync the whole 1TB array :-/.
