Btw, both drives work fine as far as the final .ogg file is concerned. It's just that one seems to take a roundabout way to get there. Also, the same thing happens if I leave off the pipe to oggenc and send cdparanoia's output directly to a file. Also, since I can still use both drives with no problems, this is not a critical issue by any means. It's plain old curiousity. I'd rather use my Sony drive to rip CD's because I'd rather not 'wear out' the HP drive on anything other than DVD's. I'm beginning to think this is more of a IDE-SCSI issue. Can you tell me if cdparanoia issues the exact same mmc-3 commands to each drive, regardless of its type/vendor? Maybe the kernel has to do some kludgy workaround for some CD/DVD-readers (as opposed to CD/DVD-writers) which requires some buffering to disk? In which, case I'll stop bothering xiph people about it. Actually, while writing this email, I've realized that my DVD ripper program probably behaves the same way. So it isn't just cdparanoia.
