If you are using the legacy IDE layer you want to tweak WAIT_CMD. For testing, you can make it really large and see if that impacts your problem. A drive vendor once told me that it could take more than a minute for an IDE drive to complete a command. I no longer purchase drives from that vendor.
I'm not sure what libata uses, but my guess is it defaults it from the SCSI layer.
If tweaking these time outs make your problem go away, odds are what happened was that your drive remapped a few more bad sectors and now takes a little too long to complete commands. The linux ide error recovery code does a WIN_IDLE_IMMEDIATE when there is a problem. This is allowed by the ATA-2 spec, but confuses most modern drives. So once you start getting errors, often the drive gets so confused, you never stop.
