SubjectRe: FW: PDC202XX DMA loss in 2.4.21-pre3-ac4
The "Hardware ECC Recovered" indicates the number of
ECC errors corrected in the drive. Do one thing. Try
to swap the drive with the drive on another ATA cable.
So, swap /dev/hde with /dev/hda (or whatever)
physically and check if the error follows the drive or
the ATA cable.

If it follows the drive, you may have to replace the
drive. Additionally, from the SMART error log #5:

00 04 01 0b 4f c2 e0 51 279972

indicates an aborted command (0x04) at the sector
0x0c24f0b. Try to read from that sector doing a "dd"
and see if the dd aborts too.

If the problem follows the drive, you should then run
a DOS based diagnostic utility (from the Maxtor site)
to determine if there are physical defects on the
drive ...

Thanks
Manish
