It's a monitor for IDE hard disks. I've also seen it fail to start in
some cases, but only on systems that don't actually have any IDE hard
disks (CDroms don't count.)

Stephen, is it only for IDE disks or does it work for SCSI too?
It's just that I noticed in the /etc/smartd.conf file that you could
uncomment the line:
/dev/sda -d scsi
Sorry for butting in here, but is there any use in having smartd running
one has a SCSI RAID system?
Thanks in advance,
Ross

Stephen, is it only for IDE disks or does it work for SCSI too?
The latter, more
precisely, for newer SCSI
From man 8 smartd:
smartd is a daemon that monitors the Self-Monitoring, Analysis and
Reporting Technology (SMART) system built into many ATA-3 and later
ATA, IDE and SCSI-3 hard drives.
Sorry for butting in here, but is there any use in having smartd
running
one has a SCSI RAID system?
Of cause; smartd/SMART try to monitor hard-disk sanity,
no matter if
using RAID or not.

Mine fails as well. I don't have any IDE disks in my machine. I have 2
SATA drives and 1 IDE dvd-rom and 1 IDE dvd-ram drive. Would I be okay
disabling this service as well?

Bottom line is you do not need smartd. Having said that, if your devices support
it, IMO you should run it. If properly setup (and enabled in the BIOS) it can
give you warnings of impending disk failure. There are numerous links available
via google that will explain this better than I can. Try googleing for smartd.
Smartd will for sure monitor smart enabled SCSI disks. I do not know about
SATA but since this is a new technology my guess would be that it will monitor
them as well. IIRC, there was also a series of articles in Linux Journal a few
months back on this.

Actually, smart does not need to be enabled in BIOS. If it is enabled in
BIOS, the BIOS will check the smart status of the drive on boot up, and
if it finds a problem, it may disable or ignore the drive. smartd will
still work if smart is disabled in BIOS.

If the drive is on a SATA controller that is using libata, smart will
not work (yet). If the drive is using IDE mode, and the drive is
supported, it should work.

Yes, you are correct. I found this info about 5 minutes after I sent the above.

It should be noted that smartd will not work on scsi drives that are
part of a hardware raid array. Those device are masked by the raid
controller and accessed very differently.

Neither and nor ;)
SMART is implemented into a hard-disk's controller (into the board on
top of the hard-disk; not into the hard-disk controller on your
motherboard).
smartd is a userspace program that tries to communicate to the SMART
support on each single hard-disk.
Anything else inbetween (busses, BIOS, controllers, kernel, etc.) can
interfere. So if a hard-disk has SMART support on-board, and if you can
access the hard-disk's directly, you'll probably also be able to use
smartd.
If not, you'll probably not be able use smartd/SMART.
Here come HW-RAID controllers ...
Yes, they might prevent you from using smartd, they might have an
option/mode to access each disk individually, they might internally
apply SMART to monitor disks themselves, they might let you pass though
SMART commands to individual disks, they might have SMART implemented
themselves ...
I.e. chances are not unlikely smartd will not work with HW-RAID
controllers. With SW-RAIDs and individual disks, it works.

2 SATA drives and 1 IDE dvd-rom and 1 IDE dvd-ram drive. Would I be
okay disabling this service as well?
Rather than disabling it, I'd add the sata disks to
the /etc/smartd.conf file. Having a message from the daemon when a
drive senses an error sure seems like the right way to me. Ymmv of
course. It takes no or very little resources to run it.

Two other things. Some older disks don't support this daemon. Also I
noticed there is an option to enable this service in the BIOS of one
of my machines.

A lot of responses already, but I think there's one other reason why
smartd might fail: if SMART is disabled in your computer's BIOS
settings. smartd talks to the hardware to get info about the disks and
if it can't get a response from the hardware, it will fail to start. It
was a while ago, but I'm pretty sure that's what happened to me.
