having issues with reading a dvd-r disc!! Help!

[coady2000]

ok..here is my deal:

I have a p4,3 gig processor..2 gigs of 3200ddr ram...dont know if that really applies to my question, but just trying to cover myself..

On my secondary IDE channel I had the following setup:

A Sony DRU500A dvd burner set as my master (with 2.0h firmware) and a standard cd rom (52x) set as the slave on the same ide cable.

Awhile back (my system has been upgraded recently) I had made data disc copies of some mp3's, pics, etc onto a 4x dvd-r media. These discs had worked when I made them off the same burner I currently am using (Sony). Well, since my upgrade, when I put these discs in my burner to read, it doesnt even open. Its like its not reading these discs that I know for a fact have worked in the past. They have worked over at friends, work, etc. For some reason not working on my Sony.

Thinking that maybe my drive may have been going bad, I bought a memorex dvd rom\cd rom drive(just a reader..not a writer) to replace my standard 52x drive.

So I hooked it in place of my standard drive as a slave to the Sony dru500a's master. I put my disc in and bingo! The disc opens up!! I was so pumped! But...(there is always a but!) When I try to copy the data off the disc I get a "Cyclic Redundancy Check" error. Arrrrgh!

So...knowing that these discs work elsewhere, what could be my issue? Could it be the jumper settings? Could it be my firmware on the Sony? (the Sony was able to read these discs when I originally made them...my pc has been reloaded several times since I made them) Could I possibly need some sort of driver loaded such as an ASPI driver?

Any help would be greatly appreciated!!!!

If you have XP just delete the IDE controller under device manager. Then reboot. XP will auto load a driver for it. Then make sure it's set to "DMA when available".

Not sure if that'll work but It's worth a try. I would also reload the ASPI like you said.
