I've had a few problems with Maxtor too, recently. This may be
temperature related, although it may be because the system is too cold
if anything.

I'm currently using a Maxtor 40GB drive as my main OS device, plus 2x
80GB Maxtors in a RAID1 array (hardware controlled). All drives are
ATA.

My main OS device failed recently - after less than a month, and this
one was not protected by RAID so involved an OS rebuild. I'm now
starting to see "SCSI error - not ready" on one of the RAID disks.
Again, this disk is less than 2 months old. I build my slimserver host
around early Nov last year.

My RAID disks are mounted in Antec HDD cooling caddies, although since
the server is not inside the house (it's in "The Conservatory" -
basically a plastic box on the side of the house) it gets pretty cold in
there. Ambient temp can get as low as 5 degrees overnight. Case temp
normally fluctuates between 10 degrees and 25 degrees, depending on how
cold it is overnight.

The operating temps of the Maxtor drives is rated down to 10 degrees,
although I'm still a bit concerned that 1 drive has failed and the other
one is looking suspicious. The reason I'm concerned is that case temp
should bottom out at 10 - but only rarely. It will normally be warmer
than that simply due to CPU fans spreading the warm air around inside
the case. CPU, Celeron 1.4GHz, is running "folding at home" application
so is permanently running at approx 50% - this is intentional to keep a
minimum temp inside the case.

If the other Maxtor disk fails, the I will be switching to a different
HDD manufacturer when I RMA it.

and these are supposed to be near SCSI quality/nearline storage drives
with a claimed 1m hour mtbf (in that sort of usage). I'm using one of
these in my Shuttle XPC and have been having trouble with gaps appearing
in my MP3s. I defragged recently and havent noticed anything since but
i'm still suspicious of the drive. However, i ran all but the
destructive Maxtor drive test utilities without identifying any issues.

I wonder whether these 250gb drive are particularly hot/sensitive to
heat? Shuttle XPCs are pretty tight inside and i'm sure cooling
suffers.

Can anyone recommend a temperature monitoring app for XP that doesnt
take over control of the fans - i'd like to monitor temps whilst leaving
the inbuilt app to control fan speed (Speedfan takes over).

I'd tend to think your problem here is humidity related, not
temperature. You've probably got dew forming in the mornings, which
can't be good for hard drives. You might want to start monitoring that.

My server box (linux, running slimserver as well as light-duty web/mail
and some other services) is in an unheated room in my basement, and I'm
in constant fear of this. That and the pipes bursting and spraying
water all over the server when the temp dips to -40. :/

I'm having my furnace replaced in the spring, and I'll see if I can get
a rad dropped into that room at the same time, so I only have to get
through one winter like this. :)
