Hard Drive Spindown
To reduce the noise generated by my NAS device (a LinkStation hacked to run Debian) I'm using hdparm -S 120 (spindown after 10 minutes). This seems to work, but now I'm getting this when (I think) it spins back up:
Jan 31 10:29:22 localhost kernel: hda: drive_cmd: status=0x51 { DriveReady SeekComplete Error }
Jan 31 10:29:22 localhost kernel: hda: drive_cmd: error=0x04 { DriveStatusError }
Anybody know why this is, and if I can stop it? I'd ignore it but smartd mails me every time it happens...
It's experimental though, so beware :-)
However, I've also seen this before on drives that are about to die (nastily once).
I associate "DriveReady SeekComplete Error" and "DriveStatusError" with failure. It's happened maybe 6 times to various IDE hard drives of decent age. Then again, it may just be some kind of error due to the spin up and is harmless.
If anyone can read a SMART log without getting confused, then I can paste one of those.
Seriously, good luck with that. Start backing up immediately.

if my latest comment helped you solve the smartd problem, would you make me a favor? please post the link in this article's body (maybe as an update) so people will have an easier time finding the answer.
One small warning: I've used hdparm in the past on a few very simple pc's that I used as servers. They had 2.5" harddisks, but 2 out of 3 disks died within one year. I've since removed the hdparm command, and the third disk is still running (for more than 3 years now). My experience from this and other disks is that disks often die at spin up (or spin down), and therefore, I try to avoid as much down spins as possible. I just take the noise as an unfortunate side effect. I have to note that this experience is based on older disks; perhaps new disks are more robust. YMMV.
It's totally harmless, and doesn't mean your drive is dying.
