Cool. > I did see this error increase in 24hrs, but that was on a disk that was > off the motherboard.

This is at the SATA layer, not the ATA command layer. It's completely normal/okay for a drive to have this number increase, especially if the machine is shut off, force-reset (via reset button), or in some cases simply soft rebooted. Nothing to worry about here; no need to adjust cables or otherwise. Values 6, 12, etc. are all perfectly reasonable and will vary from system to system based on use. -- | Jeremy Chadwick [email protected] | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, US | | Making life hard for others since 1977.
