It looks pretty much it is LVD. When using the Symbios Configuration Utility it says: SCSI 2 Identification TANDGBERGSLR100 0402 MB/sec 80 MT/sec 40 data width 16 scan ID yes scan LUNs>0 yes disconnect on timeout 10 queue tags on boot choice no Above information are similar for disk and bus controler, except the SCSI target and the identification string. >May-be 40 MB/s burst is already enough to feed the tape fast enough to >allow it to stream data. It is actually, just I am trying to understand. In fact I got the drive but there is a shortage of media... The wonders of living in far East :) Merci, Olivier To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-scsi" in the body of the message
