IANACG (I am not a computer geek) - however I did a little Googling recently on this 'cos I’m thinking of getting a new drive, the answer seems to be mostly yes you can use SATA and IDE at the same time (with XP at least).
This link may be relevant (Or not!) It’s about running two SATA drives non-raid, not a IDE with a SATA, but
sounds like your prob -
(That’s Administrative Tools >Computer Management >Storage> Disk Management BTW)
Otherwise check to see if your MB is meant to do both IDE channels with SATA enabled and if so update your Bios and any drivers to the latest versions (SATA being newish people seem to be having “issues” with getting different combinations of hardware working harmoniously)
However some motherboards apparently disable the primary IDE channel if SATA is enabled (seems unlikely if your Bios is seeing the drive)
- If this is so you could put the old drive on the secondary IDE channel (if you’ve only got one CD/DVD on it already). There’d be a performance hit of course - but if it’s just got files on not too bad (same with putting the drive in a USB2->IDE or Firewire->IDE external box - which would also make your data portable)
A better solution is probably to get a SATA->IDE adaptor (IIRC these are pretty cheap) so the old drive can sit happily on a SATA channel and everyone’s happy (tho’ you may need to play around as in the above link to set it up as a non-raid drive)
