The drive still has a bad sector. You are having trouble because the
error recover in the Linux ide code is not the same as Windows and
most drive vendors care about Windows, not the ATA-Spec. On top of
that Linux switches out of DMA mode once it hits a bad sector, so the
drive will be very slow from the on.

The only way you are going to fix the problem is if your drive has
some spare sectors still available, and you do a write with out a read
to the bad sector.
