Thanks, wasn't aware of that functionality. Works like a charm.

I've replaced the cables with a different brand I had laying around,
and I haven't seen a problem yet. I'll need to test it heavily, though
to see if I can trigger anything to pop up.
I didn't mention it before, but I'm also getting these errors every
time I boot. I'm thinking they're related to the drive not supporting
cmds that smartd is sending it. If so, is there any way that
libata/smartd can handle this more gracefully? This stuff spews into
dmesg and gives a scare that there is a real hardware problem that may
cause data corruption. I get exactly 6 instances of each of these two
blocks of output prior to reaching the login prompt:
ata1.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x0
ata1.00: cmd b0/db:f8:00:4f:c2/00:00:00:00:00/00 tag 0 cdb 0x0 data 0
res 51/04:f8:00:4f:c2/00:00:00:00:00/00 Emask 0x1 (device error)
