Are the CD-Rs from the same vendor/batch? Could it possibly be that there is some problem with firmware recognizing those disks? > i also tried this with audio cds and here recoverdisk(1) fails no matter, if > it's a CD-R or a CD-ROM: I think that it's not supposed to work for Audio-CDs with cd(4) [unlike acd(4) and then with bs of 2352]. 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 _______________________________________________ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
