I need to copy a floppy!

This is going to sound strange.

I have several Okuma lathes and milling machines. These are robotic
machines where I hand write programs for each job, and I have a have a
15+ year collection of programs stored on the machines and on
floppies.

I want to make backups of these programs, but here is the rub: The
machines use Okuma format on the floppy disks. The hardware is a
standard 3.5 IBM floppy disk drive, but the format is nothing like DOS
or FAT or anything like that. The newer machines have the ability to
read both FAT and Okuma floppies, so I know the hardware is compatible
with the floppy drive on a standard PC.

Here is my problem. I have over a decade of programs stored on these
machines and on floppy disks. I want to back up these disks because
some of them are old and may stop working. Copying a disk with one of
my CNC machines is not really an option. (Only one drive, main memory
is way less than 1.44 megs, etc.)

What I really want to do is copy them with a PC, and I seem to
remember that back in the late 1980's, early 1990's there were several
programs (that ran under DOS) that would copy uncopyable copy-
protected floppies, back when games and such were distributed on
floppy disks. I bet one of those would be able to copy these Okuma
format floppy disks.

Problem is, I can't seem to find any such programs anywhere, and
google searches only turn up software for copying DVDs and such. Fuh!
I want something that will allow me to copy a non DOS or FAT floppy.
Does anyone have any clues where I can find some of this 1989 era
software? Freeware would be best! (duh)

Something old that runs under DOS, or a Linux bootable CD would be
great.

Trust me when I say that I don't want to pirate a 1987 version of Ms
Pacman. All of these programs were written by me, or people in my
employ.

Thanks!

Wooo, flashback! I remember having COPY2PC.COM, but it was on 5 1/4"
diskette...there was even a version that came with a special
daughterboard that went in between the drive and the floppy controller
that made it possible to copy any diskette, bit for bit. I wonder if it
would work for 3 1/2" floppies...or if I even still have it buried
around here somewhere...probably not, though. I can't remember if it
could accommodate those programs that were copy-protected with a laser
zap on the media of the diskette, but I think it did.

Ah, the days of XTREE, COPY2PC and the original Norton Utilities...

I'm betting that you want 'dd' in linux, or 'RAWRITE.EXE' under DOS, one
or both of which you probably already have.

It's for hard drives, but reading the material
suggests it might work for a floppy:

I wouldn't be so sure. If the *low level format* of the diskettes--
i.e., number of tracks, number of sectors, interleave factor-- is
unique to your old machines, then the disks are incompatible at the
hardware level with any DOS, Mac, or Linux machine.

I have no data regarding tracks, sectors, etc. I may try calling the
factory again and ask for the oldest geek in the place.

One data point: The old machines can only use the Okuma format disks.
You stick a plain old 3.5 floppy and use the format command. A PC no
longer knows what to do with it.

I can then take this disk and stick it a newer machine. This one can
read the old format, and a disk made from a standard PC. (With
filename strangeness). Still no diskcopy command, only a copy from
FD0: to BB1: or BB0: (this is where the operating system is, that say
not to mess with it. I do anyway.) . So I think the hardware is the
same.

The drive itself looks like a standard $10 3.5 floppy like you see in
any clone PC.

I find it surprising that there are zero hacks for these machines. I
has a serial port, but no way to print directly to a printer.

A long time ago I got Procom plus for DOS to emulate a punched paper
tape reader/writer via the serial port. It works, but it is a PITA,
only one file at a time, and this computer is on a cart in the shop,
full of metal dust. I do have 2 hard drives in it, and it does an
xcopy each time it boots up. But I only use it for the older lathes
which do not have floppies.

I searched my junk pile but all I could find was TRS-CROSS, which
we used for going back and forth between TRSDOS and MS-DOS.

It does do a bit-by-bit copy, but only if the disk is in the format that
the drive expects. If those disks are formatted in the 800K Amiga
format, some amount of dd on a floppy drive that's mounted at 1.44 is
going to make sense. I have no idea how you go about trying to
reverse-engineer a floppy disk format, though.

Unfortunately, a casual googling tells me nothing about Okuma OSP floppy
disk formatting, other than a whole lot of people are asking the same
question, like this:

It really depends on what sort of drive your machines use. For
example, the Amiga floppy drives could read and write PC-compatible
disks, but they also handled higher-capacity disks that a PC drive
couldn't read because the designers had made incorrect assumptions
about how data would be stored. If you've run into a problem of this
sort, you might not be able to copy your disks with a standard PC
floppy drive.

But he says that the newer lathes can read both FAT and Okuma formats.

What is TRSDOS? Tandy Radio Shack DOS?

Those 5.25 floppies did use the same drives ans IBM, but only used 35

Ah, the link didn't point where I expected. The Catweasel is a
"universal floppy disk controller" which claims it can handle all the
floppy disk formats I've ever heard of and is programmable to handle
more, so it could probably be made to cope with your disks even if
they're not standard.

The difference in the drives was in the controller firmware rather
than the read/write portion. Externally they were pretty much the same
as a PC drive.

If the software can override the drive's controller on such things as
what size a block should be and what marks the beginning and end of
sectors, then it should work. I don't know if any PC copying software
would bother to do this, though, since all PC drives used the same
standards for these things.

My first computer, which I purchased in late 1979, was a
Tandy Trash-80 model III, with serial number 000985, originally
with only 4 K of RAM and a tape drive. I gradually added to it
until it grew to 48 K with two disk drives, and an external
one Meg. Winchester hard drive.

I suppose this could be bullshit to get you to buy a drive off these
folks for a premium price, but the page suggests that there's something
at least slightly different from a standard PC floppy drive. As others
have said, it's most likely in the firmware...

If it's a plain 3.5" floppy, dd(or dcfldd, a slightly more verbose version)
should work to get the data off. Don't mount it, and access the entire
disk as one unit(i.e., /dev/sda instead of /dev/sda1).

I know this has worked for me in the past on disk formats that Linux
doesn't have a clue about.

Try asking over on rec.crafts.metalworking

They really know their stuff. If then can't help, try
alt.machines.cnc

Floppies don't have partition tables, so that's easy. But it's fd0, not
[sh]da.

If you don't care about reading the data, it's fine. Better check for
and repair bad blocks on the lathe, if you can. dd might retry
infinitely at them. If they appear, you might try "dd ... conv=noerror".
It'll write a block of nulls where the bad blocks were, I think.
