But of course!

What's interesting is that I currently have the SMART in the BIOS disabled, and the disk says it doesn't support SMART capability (per smartctl). I don't know if that's because the BIOS SMART is disabled, but I'm still going to put some pressure on it.

A real simple test for dumb drives is: cat /dev/hda >/dev/null ^^^^ change appropriately for the device and watch for errors to show up in /var/log/messages or dmesg.
