Are the CD-Rs from the same vendor/batch?

To digitally extract audio data you have to go via pass(4) and appropriate SCSI/MMC commands. > otaku% recoverdisk /dev/cd0 ./test10.iso > Bigsize = 1048576, medsize = 65536, minsize = 2048 > start size block-len state done remaining % done > 0 1048576 243052544 0 0 243052544 0.00000 > 0 1048576 failed (Device not configured) -- Andriy Gapon
