I'm using freebsd-current as of 2/9/97. An "mt status" gives the following: Present Mode: Density = 0x00 Blocksize variable ---------available modes--------- Mode 0: Density = 0x00 Blocksize variable Mode 1: Density = X3.136-1986 Blocksize = 512 bytes Mode 2: Density = X3.39-1986 Blocksize variable Mode 3: Density = X3.54-1986 Blocksize variable But the modes listed here don't really correspond what I'd expect to see for a helical scanning tape drive. I have been able to use density mode X3.202-1991 (hex code 0x14) but I don't whether is the the max density code for my drive and I don't know what other codes might be available. Codes 0x13 and 0x15 (which are listed at helical scan density codes in the mt manpage) don't work on my drive. Thanks, Tom
