Search the list archives for threads on CD ROMs. I believe the upshot is that many CD ROMs have badly implemented ATA interfaces that don't work well with certain other interfaces. (i.e. You CD ROM works OK with a CD burner that's only doing ATA 33, but can't function on a chain with a HDD that's doing ATA 100) The problem seems to be fairly common, it comes up on the list about once a month. I've seen it a number of times as well, and the solution has always been to move the CD ROM to the secondary chain. In your case, moving to the secondary chain is a problem (I assume) because you want to dup CDs at the max speed the burner will go. If you _need_ to have it work, you'll either need a CD ROM that works with all other ATA devices, or switch to SCSI devices. -- Bill Moran Potential Technologies http://www.potentialtech.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
