The problem with QIC drives is that they only support writing at BOM or at EOD. So once you have recorded 2 FM's in order to mark your very own opinion of EOD (the actual EOD is behind those two FM's), you can't undo this upon a later attempt to append more data to the tape, you'll always end up with two filemarks inmidst the tape. You can't say ``just go to end-of-recorded-media, space backward over one filemark, and write here''. You'll get a `write append error'. Boom. I think this is way worse than the potential possibility of a vaporware SCSI tape drive that might not support a notion of a physical EOD... -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-) To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
