First, three definitions and some background: ASPI (pronounced with a long A followed by "sappy") is an acronym for "Advanced SCSI Programming Interface". SCSI (pronounced "scuzzy") is an acronym for "Small Computer System Interface". IDE, in context with SCSI, stands for "Integrated Drive Electronics"; it can also stand for "Integrated Development Environment", which describes a software authoring system where the language and compiler are tied together, along with a code editor and other tools, in a single integrated program. Perhaps you already know some or all of this, but I'm sure many on this list do not... and for some reason I'm in my educator mode this morning :) Now, ASPI is a "software layer" -- basically a program similar in many ways to a driver -- that sits between certain programs and certain hardware and lets those programs and hardware "talk" to each other. SCSI does indeed primarily refer to a type of hardware, especially mass storage devices, that is relatively uncommon (mainly because of the higher cost as compared to IDE devices, which is what most of us probably have). But the SCSI standard refers not just to hardware but also the software interface. To make a long story short, you can have a SCSI software layer to communicate with IDE devices. This especially applies to CD-ROM drives, I believe because the first CD-ROM drives were SCSI devices (I may be wrong, or at least making the explanation too simple, on that point). Anyway... You mention Nero. Nero is one software package that uses a SCSI layer to communicate with IDE devices. So even though you may not have SCSI hardware in your system, if you have Nero installed then you do have ASAPI installed and will see references to a SCIS adapter which is Nero's way of connecting to your IDE CD burner. I would try reinstalling Nero before pulling the machine apart and replacing cables, which is inconvenient at best and can be somewhat expensive if you need to buy new cables. That might solve your problem. If you have installed Nero's InCD software, and your ASPI installations is hosed, that could account for the error conditions on the drives. On the other hand, I'd say that you're correct that a damaged IDE cable could also be the culprit and if a reinstall of Nero doesn't work then that's the next thing to try. Hope that helps.
