Seems to be a whole slew of bad sectors, here is what the log says:
I typically get bad sectors in little mini-batches. Under a hundred - typically 40 or so in one chunk. There are 8 sectors per block, and I guess when a block goes, whatever took it out (some dust or something? a bad alignment of metal in the media?) gets the blocks near it too.
Anyway, it still looks to me like its semi-normal. Definitely check out the bad block howto and (after removing the drive from the array) try doing a dd if=/dev/sda of=/dev/null bs=4096 skip=(whatever the sector is divided by 8) count=1
You should see the read errors in the log then, that verifies that you've got the right offset in the disk.
At that point, do a dd if=/dev/zero of=/dev/sda bs=4096 skip=(sector address divided by 8) count=1
If you repeat the read after that block write, the read should succeed - you've told the drive you don't need that data any more (you wrote into the block) so it shouuld be able to reallocate
If you take that single-block idea, and expand it to the first block address and a count= number that includes all the bad blocks, you should clear them all
??
Or the drive is shot :-). Without a SMART self-test and a check of the results where you can really interrogate the drive, its hard to say
Glad this helps though
