  SOME of HP 3.5" drives would support high density 1.44mb disk but the 9114 would not. In fact, I haven't been able to get the 9114 to work at all with any 1.44Mb disks. They might work if they were bulk erased first, I haven't tried that. But standard 720k disks work fine in them. I've found the same to be true in the 9121 and several other HP 3.5" drives. In fact, IIRC the 9122 C (emphasize C) is the only drive that I'll found that will use the 1.44mb disks.

  The capacity of the disk is dependent on the machine it's being used with and what optional parameters that you give the Format (or Initialize) command. It's generally about 710k but on the HP-41 it's only about 270k due to the small size of the 41 memory and limited disk DIR, FAT (actually LIF) and other disk info that the 41 can hold.
