You should remove the 6 to 10 translation that is already in umass(4) for UFI and ATAPI devices. I didn't do it for SCSI devices because the SCSI transport was supposed to work ok with 6 byte commands. Not all devices properly report their transport though. -- John Baldwin <[EMAIL PROTECTED]> <>< http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve!" - http://www.FreeBSD.org/ _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "[EMAIL PROTECTED]"
