This is definitely your drive gone bad.

If the drive "makes funny noises" and I/O errors are logged, it has bad
sectors. Try with
# smartctl -a /dev/sda
and look for a line like this:
5 Reallocated_Sector_Ct 0x0033 100 100 036 Pre-fail Always - 0
If the last number is >0, your drive has problems - replace it!
For a full SMART check, please try:
smartctl --smart=on --offlineauto=on --saveauto=on --test=long /dev/sda
This tells your drive to make a long selftest. It prints the estimated
time for the test to run (usually 1-3h). Then check your smart values
again. You should try to not use your drive during this time.

It is possible the drive remapped the bad sectors itself.
