It is already running in that mode.. rememberr the four devices rst0.0 thru rst0.3 have the fixed modes mentionned (though you can change each..) and rst0 has the DEFAULT mode so try a few different densities (even past 0x18) and see which ones the DRIVE accepts. also then try setting blocksize to 512 (since that's what you think you wrote) On Sat, 4 Jul 1998, Willem Jan Withagen wrote: > In article <199807030025.TAA18925@nospam.hiwaay.net> you write: > > Oke, My drive is again on line: > > [~] wjw@digi> mt stat > Present Mode: Density = X3B5/88-185A 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 > > looking at: man mt: > The different density codes are as follows: > > 0x0 default for device > 0xE reserved for ECMA > > Value Tracks Density(bpi) Code Type Reference Note > ........ > 0x13 1 61000 DDS CS X3B5/88-185A 4 > 0x14 1 43245 RLL CS X3.202-1991 4 > 0x15 1 45434 RLL CS ECMA TC17 4 > no, they are set from the drive type not the tape.

(other than finding the "old" tapedrive) obviously it is NOT 0x13.. try 0x14 and 0x15 julian To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
