Internal Remapping - Performance Penalty?

Does the process of remapping bad sectors automatically by a hard
drive (not software bad block marking) introduce a performance
decrease?

Yes. It has to. However when this becomes noticeable, so many bad
sectors have been found that your disk is likely about to fail anyway.

In fact a dying HDD can sometimes be identified because it
has become slow.

OK, thanks for the reply. I've done numerous Linear Read Tests (full,
not "Quick") in AIDA32 and there are two places where the throughput
always drops to around 12MB/s and this is repeatable every time.
SMART indicates 2 reallocated sectors, so could these two be related
or is it coincidental?
