Pioneer DVD-115 on Windows 2000 won't read DVD9's

[HillJack]

Up until recently, I've been backing up my DVD's using my DVD-RW under XP Pro without a problem. But I have an old DVD-115 DVD-ROM in my Windows 2000 SP4 box that barely gets used, so I decided to share the drive over the LAN and rip using that.

The DVD-115 will read my homeade DVD5's, data DVD's and regular CD's, but it will not read DVD9's. Windows doesn't see that there is even a disc in the drive -- Windows 2000 itself, forget the network-related stuff for now. The DVD's are fine, my laptop DVD-ROM can read them and my XP Pro box's DVD-RW can read them without problems, neither of which has DVD player software installed, just Media Player Classic. It's only the DVD-115 that is having the problem.

I've tried this, which didn't work.
I've tried installing an Adaptec ASPI layer, which didn't work.
DMA is enabled on all drives and the DVD-115 (which is irrelevant).

Any ideas? Does 2000 need something special to read DVD9's? I'd put the drive back in my XP Pro box, but I don't have anymore IDE connections available and am not interested in getting an adapter card. The issue is why won't 2000 read DVD9's, not how to add more IDE channels

I would think that your DVD-rom is too old? Some drives I had won't read CD-RW's so it's a possibilty at least.

If by too old you mean not compatible, not likely since I bought the drive a couple years back to specifically play DVD's (before I actually owned a settop DVD player), and it played everything I threw at it.

If by too old you mean the drive could be defective, I'm beginning to think that is a real possibility. It's been installed in a server for the past year or so, and has barely been used (hence the reason I wanted to have it do ripping). So essentially it's been "on" for 24/7 for the past year+, not actually doing anything.

I'm trying to find my spare IDE cables (we just moved, so they're packed in a box... somewhere) so I can put the drive in another computer with XP and test it once and for all...
