I think with data > CDs it has to be a multiple of 2k, couldn't swear to that though. If its a multisession CD dd may not do it right. Would expect cdrdao knows how to read the CD and extract each session correctly. Would be nice if cdrdao knew FreeBSD's ATA/IDE CD driver, otherwise SCSI is the small price one pays to be able to use cdrdao on FreeBSD. Had a Philips 804 CD-RW ATA drive which read cd's one block short using dd. Didn't seem to matter as the image still mounted and worked correctly when attached via vn(4) and vnconfig(8) but otherwise failed my attempt to verify after write. Sony STA CD-RW read the full disc, as does my HP SCSI CD-RW. -- David Kelly N4HHE, dkelly@hiwaay.net ===================================================================== The human mind ordinarily operates at only ten percent of its capacity -- the rest is overhead for the operating system.
