I'm looking through some old C68 code of mine, and I've found what I think is a bug in my old qformat utility which does a quick format on DD/HD and ED floppies.
Does anyone still have working ED drives and a formatted floppy? If so, can you tell me what the disc ID is at the start of sector zero please?
I have this:
'QL5A' for DD, 'QL5B' for HD and I seem also to have 'QL5B' for ED floppies - and I'm not sure that's actually true, but I might be mistaken as I no longer have drives or floppies to check.
Thanks.
Cheers,
Norm.

Re: ED Floppy Discs
I have a ED drive with some floppy. I can check tonight.
However, I will need to search online as I don't remember how to do direct sector access on the ED floppy. So if someone knows the correct sequence of command/utility to use let me know.

Re: ED Floppy Discs
It's QL5B and the sector size is 2048 bytes, so for direct access you should open 'flpx_*D4e'.

I confirm. Freshly formatted ED disk. Sector read with "flp2_*D4e"janbredenbeek wrote:It's QL5B and the sector size is 2048 bytes, so for direct access you should open 'flpx_*D4e'.
