Reading ESDI disks

I'm about to try the very same thing. I have a MicroVAX II with a sigma MSCP ESDI controller.? It can be set for soft-secoring or various numbers of hard sectors.? That is what I see is the big issue with these drives. A friend gave me two drives that had been written on a PC under *nix. I do have some cable problems which I have to work on, but my first power-up revealed one of the drives and said it recognised the fact that it had 36 sectors. However when I tried to read it, it hung.? More experimentation needed, but I am sure if the controller will read the blocks I will be able to extract an image to send to my friend to decode :-) let's exchange notes as we proceed.? My effort is inter-twined with various other actoivities so I can't say when. cheers, Nigel Nigel Johnson, MSc., MIEEE, MCSE VE3ID/G4AJQ/VA3MCU Amateur Radio, the origin of the open-source concept!
