Disk shows as DOS[A] on WB?

Pioneer500 · 23 April 2013, 11:58

I have a set of discs labelled WB 2.1 install discs. I wanted to make an adf image of them with my 1.3 500 via Amiga Explorer and use them in winuae.

Problem is when I insert them in the A500 drive they show as DOS[A] .

What is that?

The disk is formatted with FastFileSystem. Kick 1.3 does not contain FFS in ROM and thus cannot read FFS disks by default

Add this to the end of devs:mountlist:

Code:

FF0:       Device = trackdisk.device
           Unit   = 0
           Flags  = 1
           FileSystem = l:FastFileSystem
           DosType = 0x444F5301
           StackSize = 4000
           GlobVec = -1
           Surfaces  = 2
           BlocksPerTrack = 11
           Reserved = 2
           Interleave = 0
           LowCyl = 0
           HighCyl = 79
           Buffers = 20
           BufMemType = 3
           Mount = 1
#

Then open a CLI window and enter mount ff0:
After that the disk should be readable (the DF0:DOS[] icon will remain but an additional icon for FF0 will appear).

Be aware that most of the programs on the WB 2.1 disks will be unusable on Kick 1.3. You need at least Kick 2.0 to run WB 2.1.

Thanks Thomas !

Wouldn't it be possible to take a straight ADF image even without mounting an FFS device?

Good thinking!

Yes, if it works for NDOS disks, there's no reason at all why it shouldn't work with an unrecognized filesystem disk.

Assuming that Amiga Explorer allows imaging of NDOS/unrecognized disks. I've never used it, I've always used the old manual technique of transdisk or TSgui split into two parts and copied over via 720KB FAT12 disks :P

Yes, Amiga Explorer does allow NDOS disk images to be sent to the PC as ADFs, but they are given the default name "DF0.adf" or "DF1.adf", etc. depending on whether the disk was mounted in the Amiga's internal drive or an external one.

Of course, in this case the default filename might well be "DOS[A].adf", but the image itself should be nonetheless valid for that.
