I had an MSI CD-R drive, and some silver no-name brand discs.. I started to have issues with the drive not recognizing the media as new, blank media... I did some looking around, and ordered the highly recommended Lite-On CD-R from Newegg.. it seemed to work okay, but today I go to burn some discs, and it fails to recognize some of the media. Not knowing what the deal is, I first replace the cable from motherboard IDE to drive, and confirm jumper settings on it and my DVD-ROM drive, all good. After the cable swap, I burn the 2 discs I needed to.. and leave it at that.. well, I come back later to do some more, and now it is failing to recognize the discs again. The media I am using is some I bought off of ebay, but I've bought previous batches from this guy with no issues. I thought it might be an issue with those, until this next thing happened. The free disc that came with the drive, will sometimes read as a fine, blank disc.. then after I check some of the ebay media, the free one that was fine 2 minutes ago comes back as invalid.. Nero says "No disc inserted or drive not ready, please try again".. This is what it did with the old drive.. I've reformatted/reinstalled trying to make this go away.. I updated bios, no firmware updates are available.. updated the via 4in1 drivers.. can't figure this out... Any ideas?
