I thought they would be the same through ASPI, wouldn't they?

As far as I am aware, no. ASPI stands for the Advanced SCSI Programming Interface, so it seems unlikely.

Update: I'm wrong! According to wikipedia: Support for ATAPI interface (such as IDE) was later added.. (Shows how long it is since I did anything with ASPI! :)

However, the problem is that MS chose not to include an ASPI interface in XP/2000, so unless you've installed one yourself (such as the Adaptec freeware implementation), then using ASPI won't work.

Maybe his program uses other means to detect IDE optical drives?
