From previous reports, i've got the impression that the SCSI implementation of these drives is of very poor quality. Your drive seems to support this suspicion. > st0(aic0:0:0): command: 10,0,0,0,1,0-[0 bytes] That's a WRITE FILEMARKS command, requesting the drive to write one filemark. > st0(aic0:0:0): ILLEGAL REQUEST asc:80,81 Vendor Specific ASC ...which the drive choses to not implement, apparently. Even more, they're using a private ASC/ASCQ, why the heck? WRITE FILEMARKS is flagged `mandatory' in the SCSI-2 specs. If your drive doesn't implement it, it can't be called `SCSI'. Return it to the vendor, or request a functional firmware agreeing with the standard. -- 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. ;-)
