I'm using this command line: cptp -hm 1 of=- | cptp -hm 0 if=- (tried it without the -h too) And getting this output: After 0 tape marks, after 0 blocks: tape image format error on standard input And this error in /var/log/messages: Mar 30 18:23:24 billmax /kernel: (sa1:ahc0:0:2:0): 64512-byte tape record bigger than supplied buffer Mar 30 18:23:24 billmax /kernel: (sa1:ahc0:0:2:0): tape is now frozen- use an OFFLINE, REWIND or MTEOM command to clear this state.
