Re: The Copyprotection Wars

The article does mention the then-new Copy II PC Option Board, which provided similar functionality. Honestly, I'm surprised most vendors dropped floppy disk copy protection in the very late 80s, and magazine software reviewers had enough guts to publicly chastise those that continued to use it. As ...

Re: Kryoflux has lots of read errors on 5.25" floppy - but works in PC?

Check the density line setting. It should be "high" for low density disks and "low" for high density disks. (yes, confusing, the menu item refers to logic level of the density pin, that happens to be opposite of the actual use and some non-IBM PC drives reverse that) Also check that the target RPM f...

Re: Re-attach a detached Hub Ring?

Unless you have some crazy mineral problems in your area, tap water should be fine. Distilled water might technically be better, but who keeps truckloads around and has time to heat it all up? Some soaps will leave a waxy residue on the disk, and you don't want that. I'd skip the soap unless there w...

Re: Re-attach a detached Hub Ring?

That sounds a lot like what my Wabash disks did if I didn't wash them first. Putting one in a drive would cause it to screech like crazy and rip off the surface, even if I used a q-tip and alcohol to clean the disk first.

Re: Re-attach a detached Hub Ring?

Thats too bad. From the sound if it, it was probably a goner anyway. What cleaning method did you use? I think the worst I have encountered so far were disks with seemingly small scratches that "hemorrhaged" brown magnetic particles when cleaned with a q-tip and alcohol, and some Wabash disks with s...

Re: Re-attach a detached Hub Ring?

I'd also love to hear any suggestions on how to best re-attach these without making a big mess. And yes, if they are not centered correctly that can cause problems. However, the hub rings are not really needed. The hub rings were included on most later 5.25" low-density media to address some kind of...

Re: Cannot read MFM img file from within Dosbox

DOSBox isn't meant to be used that way. Extract the files from the disk image with a tool like WinImage and place them in a directory, then mount that directory. Unless they have fixed it in more recent versions, DOSbox is really, really brain-dead about directly mounting images. I always have to ma...

Re: Write a Mac 400/800K sector image using Kryoflux

Yes, the above method is for writing a Mac variable bit-rate disk with just a standard 300RPM 720k/1.44mb drive and a Kryoflux. It does require the use of a low-density (720k) floppy disk, or a 1.44mb disk with the density notch covered. It is good to know the Kryoflux should be able to deal with an...

Re: Write a Mac 400/800K sector image using Kryoflux

There is a new update to PCE and the tools: http://www.hampa.ch/pub/pce/pre/pce-20160308-72f1e10-pfi-win32.zip With this version, you can now use "raw" 400 and 800k sector images instead of just DC42. For example with an 800k image instead of the first line above, use: psi test.img disk1.psi -I mac ...

Re: Bad Distribution Disks

Right, don't spin a disk in a drive while it is still visibly wet. More friction. Did you re-insert the cookie in to a known good jacket? The liner in old jackets can hold on to dirt, residue from the air, and also degrade over time. Here is a description of a cleaning method I often use that works ...
