Fat format discs.
« on: May 06, 2007, 07:54:01 PM »
I have lots of floppy discs that i used on a old ms 98 box,That system is long gone but there is a ms system somewhere in the house lol:
Is it possible to format the discs so my Amiga 1200 can Recognize them?

I did that on my sons box but the Amiga would not Recognize them ,It would not open the files that i put on it there was just ??? below the disc on the workbench desktop.
The file was amiTCP stack that i extracted from the archive.

So lets clarify, what are you trying to do exactly? Just make the disks work on amiga, or try to make both amiga and pc read the same floppies so you can transfer files over?

If you want to transfer the files over: Format the disk 720KB (if the floppies are HD ones, you need to tape over the extra hole). Then on Amiga you must move Devs/Storage/DosDrivers/PC0 to Devs/DosDrivers and reboot. After this the amiga can read PC 720KB floppies.

The A1200 can't read HD disks... put tape over the hole on the other side of the Write protect hole (ie not the Write protect hole)...

@Piru & odin

Thanks for the help there, with a few big rolls of sticky tape i should be able to use these floppy's as back up discs for my Amiga.

The floppy icon on the screen is "PC0:" , not DF0: .

If you want to use the disk on the Amiga only, you don't need to tape anything, just format the disks and that's it.

XP boxes needs the tape, and the disks must be formatted in 720k (double density - DD), not 1440k (high density - HD) in order to use them on the Amiga, too.

For better, suitable way, save the contents of the disk on the peecee, then format in the miggy to use all of them as transport (or backup).

The cli line is:

"format drive PC0: name watheveryoulike noicons"

 No quotes, obviously. ;-)
Goodbye people.

I\'ll pop on from time to time, RL is acting up.

Unfortunately, it will ALWAYS be like that for a simple reason. You cannot read (or write) 1.44MB floppies on an A1200...

UNLESS they were formatted in 720k or 880k format AND you plug or block the HD hole on these disks AND you put PC0: in your devs:storage folder.

The drive in the A1200 does not support HD formats.

@ psyco

Indeed! You cannot read/write to 1.44MB HD disks with the standard floppy drive of an A1200. But you could transfer files using an Amiga disk :-)

1. Insert the Amiga disk into the floppy drive of your PC

2. At an MS-DOS prompt type:-   format a: /n:9 /t:80

The Amiga disk will be turned into a 720K PC formatted disk which you can use to transfer data between your PC and Amiga.

Personally I've found that if I take the floppy to an A1200 and use PC0, I get a load of jumbled up or shortened file names.

(as you have said, when you first insert the PC formatted floppy you will get an icon DF0??? or DF0:Unreadable. But other icons appear for the same disk when you double click on other drivers as you can see in the screengrab below)

The best result I've found is to put the file fat95 into the L drawer of Workbench and then double click on the icon MS0.

In this screengrab created in an A1200 running OS3.9, you can see how a photo called 'Here is a pic.png' shows correctly using fat95 and MS0, but its name is shortened and displayed incorrectly under PC0 and CrossDOSFileSystem :-)

I dig that floppy disk icon with a Windows logo on it :-D

:idea:  You could always get an A4000 with High Density floppy drive to make use of all your 1.44MB disks. Either for tranferring stuff to/from your PC or turn them into 1.76MB capacity Amiga disks  :pint:

The place to put the "PC0" icon is "devs:dosdrivers", no other. :-o

Quite correct of course mate :-) If you want PC0 activated each time you boot then Workbench:Devs/DOSDrivers is the place for it. I just put those files into RAM to show them in the  screengrab :-D

However, you can put PC0 or MS0 wherever you like and just go and double click on them when needed. To avoid unecessary icons on my screen I actually have mine in Workbench:Storage/DOSDrivers and activate them using a ToolsDaemon menu. If I insert a PC formatted floppy I then hold down the right mouse button and select 'Fat 95 Floppy Disk' from the menu as the path leads to MS0 :-)
