Just so happens I have those round ide cables. I also have two ide
drives hda and hdb.
hda is 80Gb Western Digital while hdb is 160Gb Maxtor. I'll try
replacing the ide
cables and also place the 160Gb drive on ide2 (hde). Hope this works and
solves the

I do have SMART set on in the BIOS along with smartd running. The command
smartctl -H /dev/hda reports:
"SMART overall-health self-assessment test result: PASSED"

Thanks for all who replied,

AKAIK, SMART only tells you about internal drive issues. It does not
help diagnose cable / controller / power issues.

For IDE I have not seen a lot of power or controller issues, so I tend
to worry about the cables a lot.

For SATA, power seems to be the main cuprit.
