Apologies if I sounded too harsh! Please understand that InCD troubleshooting typically boils down to checking quite a few points carefully. An additional complication in your case is that you don't have your friend's computer at hand, so it's better to be slow but sure.
In fact your latest post raises new hopes! Namely, in view of your earlier posts, I assumed that you had never got InCD running with the Polaroid burner. I was thus wondering whether InCD's support for BurnMAX48 was really true, and I asked you about IDE connections, chipsets, etc.
Hence your latest information that InCD 3.52.20 had worked on your friend's box until W2K had to be reinstalled is crucial! Thus, if the hardware has not changed, we are facing just a software problem.
So is my assumption that the hardware has not changed recently correct? Then you might consider going back to the original IDE configuration, although switching IDE channels shouldn't matter (of course, you should verify that the cables are in good shape).
Concerning software, did you start by installing W2K on a reformatted disk and then upgrading to SP3? What other software did you install except for Nero and InCD?
Here two aspects are important. First, for many users a fresh W2K installation actually also means installing a lot of their favorite programs. For instance, if you have installed Norton CleanSweep, then don't be suprised about InCD installation problems! Second, if you have installed any program with burning capabilities (such as WMP, MusicMatch, etc.), then you may need to remove conflicting drivers as in the InCD guide.
As for InCD versions, it might be safer to revert to 3.52.20b, since it worked before. On the other hand, it is highly unlikely that the Polaroid burner would work with 3.52.20b, but not with 3.52.40.
InCD doesn't need any additional ASPI layers! Thus you didn't need to install Adaptec's ASPI, since it wouldn't fix anything for InCD. I would definitely remove ASPI 4.72. If your friend had Adaptec's ASPI before the crash, you could use ForceASPI to switch to 4.60.
