Hello all. I decided to rip my entire CD collection before I end up scratching every disc I own... Using Grip/cdparanoia/lame, things were working pretty well until I hit a few snags.. One of my discs wouldn't read properly. I took it out and checked it for scratches-- couldn't find a thing. I put the CD aside to try later. I finally got to "D" in my archives and I had three similar failures in otherwise perfect-looking media. The last one I tried was freshly opened (I removed the plastic wrapper) and I received the failure again, checked the disc-- not even a speck of dust. I tried it in all three of my optical drives-- here are the errors that are repeated when trying to access different portions of the tracks (I only pasted one per drive; each error is repeated for each attempt to read that track): acd0: READ_CD - MEDIUM ERROR asc=0x02 ascq=0x00 error=0x04 acd1: READ_CD - MEDIUM ERROR asc=0x02 ascq=0x00 error=0x00 acd2: READ_CD - HARDWARE ERROR asc=0x09 ascq=0x01 error=0x00 Just FYI: acd0: DVD-R <SONY DVD RW DW-U10A> at ata0-slave UDMA33 acd1: CD-RW <OPTORITE CD-RW CW4802> at ata1-master UDMA33 acd2: DVD-ROM <Pioneer DVD-ROM ATAPIModel DVD-106S 0122> at ata1-slave UDMA66 also, atacontrol(1) shows these drives still at those UDMA transfer rates. They burn most of my discs just fine-- only a few it's having troubles with (most often at the end of the last track, just prior to a data track, but also twice at the start of the first track when there is no data track). I'm assuming it might be an anomaly with the atapi driver. I've tried the following techniques on each drive (with the exact same results): cdparanoia -d <device> -X <track#> <wavfile> dagrab -d <device> -n 128 -f <wavfile> <track#> dd if=<device>t<track#> of=<pcmfile> bs=2352 I have not tried ATAPI/CAM yet-- I try to reboot as seldom as possible, so I might get around to it this month. I am using 5.1-RELEASE. Any help would be appreciated. A special thanks to Søren (sos) for getting burncd(1) to work with DVD+RW media! -- Rick C.
