I suppose dd's default blocksize of 512 Byte kills performance on several CD-Drives. I use dd if=/dev/scd0 of=tmp.iso bs=2k count=$(( `isosize /dev/scd0` / 2048 )) which is reasonable fast (and avoids reading the unreadable sectors at the end) Rainer -- KeyID=58341901 fingerprint=A5 57 04 B3 69 88 A1 FB 78 1D B5 64 E0 BF 72 EB
