Were you burning CDs with enough contents to get close to the capacity of the disk? (~650mb-700mb?)
I had a similar issue, also in the late 1990s, so I understand the stress around wasting those $20 blanks. Found out a few years later that the drives were defective, and would often (but not always!) have buffer errors when burning discs close to capacity. (something that you'd often WANT to do, to maximize the value you're getting from those $20 blanks!)
There was a class action lawsuit, and I eventually got a replacement drive (no relief for those wasted expensive, blanks). But the vindication that it was defective hardware, and nothing I did wrong helps. The manufacturer of the drive was Philips/Magnavox, but there were some other brands that were all linked back to this same defect that the class action lawsuit covered.

Or at least they were back then.. I suspect the damage done by poorly constructed FIFO buffers now is just more hidden, not exactly lessened.
- simonklitj 6y agoA little interested! What exactly are FIFO buffers?

- kevin_thibedeau 6y agoI was bulk ripping CDs a few months ago and was running multiple SCSI drives to increase my throughput. The current Linux SCSI drivers will lock up the bus when you insert a disc and ruin any transfers already in progress on another drive. You'd think something like that would have been resolved at this point.
- dylan604 6y agoAn actual SCSI device? And you're complaining about "by now". How old of hardware are you using? "By now" fixes are included in modern hardware on USB.
- kevin_thibedeau 6y agoI have a number of Plextor CD-ROM drives that are more desirable than DVD-ROM for CD audio extraction. I have one USB Plextor but they command a high resale price. The point is that basic bus management should be sorted out and it clearly isn't.

- mjg59 6y agoA lot of CDs aren't in perfect condition, either because of scratches or things like https://en.m.wikipedia.org/wiki/Compact_disc_bronzing https://en.m.wikipedia.org/wiki/Compact_disc_bronzing. When faced with damaged data, the quality of the drive and its firmware will influence whether the data stream corresponds to the original content or not.
- BuildTheRobots 6y agoThanks for the explanation - I misinterpreted the OC to be about audio quality rather than just trying to recover data from damaged media.
- mjg59 6y agoGiven a perfect CD the drive is probably not going to have significant impact, but for an audio CD that's been exposed to real world conditions there's a bunch of ways the drive can make a difference to the recovered data.
