In articles ... Michael van Elst and Enno Davids write about SCSI disk and tape support at the exec device level. A (standard or fast) DOS file system is associated with a SCSI disk thru an exec device (e.g. hddisk.device) that looks like the trackdisk.device. There is no corresponding DOS handler for tape drives at present. A backup program that I know of that uses SCSI tapes (BRU) does so via SCSI commands issued directly thru the tape drive thru the same exec device using the HD_SCSICMD command described in the 1.3 include file <devices/scsidisk.h>. We encourage all applications requiring access to something other than a magnetic disk on SCSI to use this command, and all writers of SCSI exec-level drivers to support it. - Kodiak -- Bob Burns, amiga!kodiak _ | /_ _|. _ | Commodore __ |_) _ |_ _ )' |<(_)(_)|(_\|< /\ | ||| _` /\ |_)(_\| )(_\ | | \ Software ___/..\|\/|||__|/..\___ Faith
