Well on linux :

mount -t vfat /dev/sda /ls120, if your ls120 is the first scsi device.

but i guess with proper use of dd to clean it, and then writing a proper vfat
filesystem on it, you could handle it as a super floppy also.

what is the difference betwenn the two ?

you access it all the same, isn't it ?

i think mke2fs /dev/fd0 works, or doesn't it ?

but then you would not be able to read ls120 floppies, isn't it ?

And check it also for any other device, there is no reason i should not threat
my 20 GB hd as a single big super floppy. Well i guess there are reason, but i
still should be able to do it, and then install linux on it.

Well that's how i threat my syjet cartdrige, as a big floppy.

And i remember doing the same on an older 60MB hd.
