Backup up cassettes to PIL-Box drives

[BitWiz]

I have a bunch of HP digital micro data cassettes that I want to back up to virtual drives using the PIL-Box.

I'm trying to accomplish this without having to copy the files one at a time. I prefer to use the HP-71B rather then the HP-41 due to speed and battery life (the 71 is running off of AC).

I downloaded the MCOPY lex to the 71.

I created a LIF image with lifinit -m cass -z backup.dat

I then "mounted" that .dat file in ilper.

I then used MAXXCOPY :1,0,512,:6,0 command on the 71. After like 15 minutes it finished. When I did a lifdir of backup.dat the files were not there.

Device 1 is the 82161A Drive and Device 6 is the virtual 9114B drive in ilper.

What is the easiest way to backup my tapes to the PC via the PIL-Box?

Thank you.
