Hi Neil,

I saw very similar on my system tonight. (But I don't think it's seasonal!)

Here's what I think caused it:

I have a DVD-ROM on secondary master (hdc). Secondary slave (hdd) is  
normally unused, but is conneted up to a harddrive caddy for using as  
backups. I'd been fiddling around with stuff, and had disabled the  
secondary master in the BIOS. Therefore, when I put my caddy in tonight, I  
got messages similar to yours above. I'm wondering if it's because the  
caddy drive was expecting the DVD to be present at BIOS POST. With the  
BIOS not bothering with the DVD, the harddrive might have expected to be  
set as CS or Master, and not jumpered as it is as Slave. I *think*  
(wonder?) then, because Linux (AFAIK) largely ignores any drive detection  
in the BIOS, it handled hdc & hdd as normal which caused the harddrive to  
have a minor hissy fit. FWIW, the drive still worked/mounted/etc fine.

It might be worth checking jumper settings of the new drive (and anything  
else on the same IDE channel) and verifying that things appear correctly  
in the BIOS.

FWIW, I'm on Slackware 12.0

HTH,
Mark
