non non DOS image

[orange]

How to read and write back image of diskette in some strange format, for eg. IBM 720K?
I've tried wwarp but it asks for 'sync' and 'track length'?
It can be copied with 'nibble' in X-Copy, but I need it as file.
Thanks.

Probably Crossdos ? It can read PC 720k physical floppies so I guess
you could use it for disk images also but never tried that.Works for
physical floppies.

You can try Win(UAE) , it can support wide range of disk images
now but you need CrossDos or something on Amiga side of things.

I have always had a dosdriver named MS0 in my devs\dosdriver folder. and i have always been able to read and write, even format 720K MSdos disks...
in my a1200...
never tried it on any other amiga...
and the MS0 was included in the WB3.0 setup disks...
Or if you have a pc with windows installed Diskcopy should be able to do the trick.

Hi pyrre,

How about Fat95 ?

See  http://aminet.net/package/disk/misc/fat95

Also allows long file names.

==============

By kind request of its author, I hereby link to his MUI tool for generating fat95 mountlists (although I could not test it since I have no MUI...):

aminet/disk/misc/fatmounter.lha

Best regards to everybody who mailed me, especially H.J. "Buccaneer" Pinkert for spending hours on testing and bug reporting!!!

I have been enjoying "fat95" for some time already as part of my private "sneaker net" towards several PCs via CF memory cards.

On massive public demand, fat95 is now trying to support FAT32, too ;-)

Feel free to send me an email on your experiences with "fat95"!"


I hope this helps.

No, what came with Workbench was a light version of CrossDOS with PC0 and PC1. MS0 is something that comes with the Fat95 archive - http://aminet.net/package/disk/misc/fat95 - of course you can name those devices freely as you like.

Anyways... one can deal with non-dos disks by using various tools that reads and writes to the device and not to the filesystem, for example one can use the raw disk handler - http://aminet.net/package/disk/misc/RawDiskHandler

Like mentioned before: Install Fat95 first, then double-click on the MS0 icon.
Now download TGui and with
this program you can now read/write PC MS-DOS 720kb floppy disks.

Sorry my bad.
PC0 it was, included with the workbench install
I cannot remember now why i installed the system with fat95.
it might have to do with the zip drive i was trying to get to work at that time...

The main part you need is mfm.device (or messydisk.device which does a similar job).

The file system used is irrelevant for disk images. You can use CrossDOS or Fat95 or even FFS if you don't want to read files. All you need is a dos driver reading Device=mfm.device.

[vince_6]

Crossdos is the way.
Also you can try DiskImageCtrl and Virtual Floppy from Aminet.
With the above you can mount the image on your Amiga.

Solved, by using MFMWarp without any special options.
Great util, pity it needs compression libraries (or is there option to save as 'raw'?).
Thanks all.

This brings in mind an old thread.
A couple of months ago I tried to restore an old backup from a 2007 .mfm file, but no luck. I`ll have to findout a way to recover the disk contents.
