I can compile lifutils, but can't mount/read a LIF formatted disk

[Kevin-McKee]

Hi, I'm not sure if you'd be able to help with this, but I'm trying to copy a LIF formatted disk. I'm able to compile and install your lifutils, but the problem is anytime I put a floppy in my drive the kernel or OS is showing messages like this

so any of the LIF commands I try to run tell me that the device is invalid. If I use a non-LIF formatted disk, I'm able to mount the disk and read the contents, so I know that my hardware and OS are capable.

Any ideas how I can get past the OS not recognizing the disk and allowing me to mount it so the LIF commands will work?

USB floppy drives are determined to the IBM PC physical format and do not allow any changes. You need an old floppy disk controller to read or write HP-LIF formatted disks. See the tutorial for details.
