That is a faulty disk. Replace it. It has already lost the data stored
on one sector, and when this happens, more fail.
The "slow disk" you are experiencing is the disk trying to re-read a
faulty sector multiple times in the hope it will recover the data.
The disk will automatically try to relocate this data to a different
sector, and mark the bad one as bad.
This is the "reallocate" feature it mentions in the error message.
Except in this case, even though it tried to re-read the bad sector
multiple times in the hopes of recovering it, it failed to do so, thus
that sector's data is lost for-ever.
It is 100% a faulty disk, and 0% a cable problem.
