The drive not showing up in Windows is really wierd. I've seen that happen from conflicts between XP and CD Recording software, especially packet writing stuff like DirectCD, InCD, or DLA, but never from installing IDE drivers. The way you fix it is by deleting or renaming the LowerFilters and UpperFilters registry values under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318} and rebooting (Windows will automatically create new default values for these keys).
WARNING: If you delete or rename these values all your CD-Recording software will no longer work and will need to be reinstalled. They are basically the list of ASPI drivers that have been installed by your different recording utils.
Got ya....
Yeah, I'm not the only one who has had this problem though.
Here is someone who used to be on the forums who tried just about everything I have tried-
"Ok, well.. I went to VIA's site and grabbed some miniport drivers and now the VIA "IDETOOL" detects the CDRW as running in DMA mode, but the CDRW won't show up in My Computer or Device Manager and scanning for new hardware does nothing. Also, in Device Manager, my PC now shows my HD and DVD-ROM as SCSI devices, but that doesn't matter much to me, figuring they still run well and are in their DMA modes.
So, it's in DMA mode, but now it's...just gone. Any ideas?"
Unfortunately, there was never a fix discussed and that person hasn't been to the forums in quite some time.
That's the same thing that happens when I install the VIA "IDE Tool".
I DID get the Hyperion 4n1's IDE Driver to be used by XP....but only for the "Master Bus"...the secondary and primary IDE channels are still using the orginal.
And yes, I did make sure that DMA was enabled in the bios.
Thanks for the help y'all!
