You may need to check your ASPI Layer. If using v 4.70, it is buggy. Either try ForceASPI to get back to v4.6 or try one of the newer ASPI's from Adaptec. Go here and download ASPICheck:
Look in the last two sections at the bottom of the page for stuff about ASPI.
If you have v4.70 ASPI, then this utilitiy will probably bug out--v4.70 has some known bugs. Try one of the other versions available at that link. If one of the newer versions still doesn't work, try going back to a v4.6 series driver. V4.60 is the preferred one for CloneCD, and I think is the version included with the CDRWINASPI link at that site. The ForceASPI v1.7 listed there will install version 4.61. Here is a direct link to v4.60.
Please read the warnings carefully. If that link eventually gets killed, you can get it from a german posting here as well:
If the lack of an Adaptec product prevents you from installing, use ForceASPIv4.6. I got mine originally from here, the link appears to be working still:
If that fails to download, there was some info on an alternate method to get around the Adaptec requirements to install their 4.6 ASPI directly listed here:
This basically involves manually installing a fake Adaptic SCSI controller to fool the installer into thinking you have one.
There have been some reports of issues with Win2000 and Me I think, but for the most part they work on just about all OS after Win95. I'm running this layer with 98SE still, but I don't use Nero-- I use the free Primo with updated engine from Veritas for my 104 PS2 Burning, and I still manually rip my DVD's with Smartripper and a DivX 4.12 conversion with DVD2AVI to maintain near DVD quality. It takes a long time I know, but the proggies were free and the end result can be ported through a retail burning app I already had. Most of it is done while I sleep, so I don't feel like I'm wasting my time really.
I am considering purchasing Instant copy or CloneDVD when it gets released though. CloneDVD will probably be built off the 4.60 ASPI just like it's little brother CloneCD. These 2 proggies look like they'll be the Schizit in DVD Movie backups.
If it ain't broke don't try to fix it! But, hell if you can tweak that bastard just a little bit more....hehehe.
