Anadisk -> VDK

Post by paul »

OK, I have an old 40/80-switchable BBC micro 5.25" floppy drive which I've got working on an old MSDOS PC. The problem is that BIOS is reporting 'drive not ready' - I guess the little LED thingy isn't working properly.

Anyway, what this means is that Anadisk seems to be able to read my old Dragon disks fine, but VCOPY/DDIR/etc just report 'drive not ready'.

So, if I have a dump from Anadisk, what do I need to do to make it into a VDK format file?

(I'm a computer programmer, so I don't mind writing a little utility to do this if I can work out the various formats, but if someone's already done it...)

Which format is it dumped? Raw sectors?

If that's the case, just adding the vdk 12-byte header will do the trick.

Thanks - got it - I had saved it with sector IDs, but got rid of those easily with a bit of C
