Reading various format 5.25" floppies on

Absolutley. FWIW, I _have_ written software related to this -- the 'LIF Utilities for Linux'. This is an on-going project (so don't moan that the feature you need isn't there, and it's GPLed. It's designed to handle the HP9114 disks only, so as to transfer programs and data between older HP handheld calculators and linux PCs. I didn't write a program to directly copy a disk (for one thing, my PC only has 1 3.5" floppy drive) -- I wrote programs to transfer between a physical disk and an image file in both directions. That seemed to cover it (just put the image file in /tmp if you don't need to keep it :-)) Of course. I was just pointing out that you might still have problems, and that a PC can't read all disks with 'western digital headers'. In particular, I couldn't read disks formatted on my TRS-80 Model 4 on this PC. I could format a disk on the PC with the same type of format and then read/write it correctly on both machines. Oh, indeed. Linux makes this a little easier (at least in the (old) version I'm using) in that there's an ioctl() call that allows you to do just about anything the hardware is capable of (some of the parameters set up the DMA controller to transfer the appropriate number of bytes, and the _system_ takes care of allocating a buffer not crossing a page boundary, etc, other paramemeters are sent to the disk controller chip without modification). I have had to do it under MS-DOS (the PERQdisk program), which was 'interesting' -- just about every other comment relates to some misfeature of the PC :-) Why me? I am not a programmer. In fact I doubt I'm a hacker [1] either. [1] In the original sense. I am certainly not a cracker. Sure, I understand 'most' :-). I was just asking because I have that program, and if it is possible to add more formats I'd like to be able to do it. If not, never mind. -tony
