I can read old 60 and 90m tapes fine. As soon as I try } to write to one of them, I get: } } Mar 19 13:43:17 wiley /kernel: st0(ahc0:4:0): DATA PROTECT asc:30,0 Incompatible medium installed Ok. That are most probably old 90m tapes, which don't have the MEDIA RECOGNITION SYSTEM lead in. If they are true DDS DAT tapes, then you can disable MRS and this way enable writing onto those tapes ... MRS was designed to protect against erronous writing on Audio DAT tapes ;-) Regards, STefan
