Since you want to make a copy of an existing disk, why not use LIFUTIL to copy the contents of the original disk to the new disk.
Then you can test to see if the HP-86 can read the copied disk without an error.
BTW what kind of disk drive do you have? Is it the HP 9121D ?
If so, have you tried the right-hand drive?
I have an 9121D with one drive being able only to READ floppies. If you tried to write a floppy, it would think for ever and then report an error (like your drive). I figured that the drive was broken and decided to restrict its use to that of a read-only device.
Since this was originally the left-hand drive, I swapped it with the right-hand drive, and disconnected the WRITE-PROTECT sensor (so that floppies always appear to be write protected). In this way, the system reports the disk as protected rather than waiting for the drive to timeout (faster).
So now the right-hand drive is my guarantied READ-ONLY drive. I can still use the left-hand drive as a normal drive, but when I copy diskettes, I have to use the right-hand drive as the source drive.
