Re: Apple II disk Grrr.....

A good question to which I don't have an answer to. No the DSK and PO disk images are only sector-based (which is why a lot of Apple // archived titles that had copy protection are cracked versions). My understanding is that NIB is a layer above this - more like what the floppy controller would actu...

Re: Apple II disk Grrr.....

Yes, for your purposes I believe you will want to convert it to a NIB disk image.

Re: Apple II disk Grrr.....

According to http://computist.applearchives.com/computist/ , various Infocom Apple // titles used copy protection, including the one you are working on. I don't know how the software works but maybe that has something to do with it? The info on that page for Infidel says it is the same protection us...

Re: Apple II disk Grrr.....

I don't know but maybe not. I have a few 5.25 drives that I use to get around similar problems to what you see here. When I do get this problem from one drive, it is not unusual to find that one of the other drive(s) is able to pick up other parts of the disk (or sometimes almost all of the disk). I...

Re: "No disk in drive"

On the small chance that it has happened, check for any bent pins on the floppy connector of your Kryoflux? While you are checking that, see if they all look clean as well. Also to state the obvious, make sure you are connecting the floppy cable the right way - I don't know what the consequences are...

Re: A few Apple 5.25 floppies can't be detected

So the "no disk in drive" problem disappeared after your cleaning or was it still a problem?

Re: A few Apple 5.25 floppies can't be detected

Yes it is quite difficult to tell if the disk is actually spinning. One trick I have used is to dry a tiny "drop" of isopropyl alcohol somewhere very close to the hub at a single location. The evaporation mark left behind can help to see if the disk is actually rotating in the drive (although it is ...

Re: A few Apple 5.25 floppies can't be detected

Based on your description, my guess would be that there isn't quite enough pressure on the disk from the spindle. You say there is evidence that the index hole is moving, but it might be that the movement was only a few degrees around the disk (before it completely lost its grip and started slipping...

Re: A few Apple 5.25 floppies can't be detected

Reading SomeGuy's suggestions made me think of a possible explanation for your problems. The disks that have this problem, do they all have their central hubs present and intact? Could it be that the hubs are absent and that the spindle isn't completely gripping onto the floppy surface? A slipping s...
