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

So just thinking this through in regards to reading Mac disks, I wonder (under the right circumstances) if it may be possible for a poorly reading drive to give better results by intentionally increasing the RPM of the drive. That is assuming that the Kryoflux can do sufficient sampling to capture t...

Re: Bad floppies :(

Sideways! Although my drive maintenance skills really only go as far as head cleaning, I would suspect either a slightly loose head (causing it to be out of alignment unless gravity assists) or perhaps the (ribbon) cable from the head to the PCB may be slightly loose/out (or the equivalent from some...

Re: Bad floppies :(

So that was after you gave everything a clean?

In regards to the Apple // formats, you should also search these forums for AGC (automatic gain control), as specifying this setting can make a significant difference to your dumping efforts.

Re: Bad floppies :(

Apple // formats for Kryoflux have been mentioned in another thread, where I gave my own recollections on the subject: http://forum.kryoflux.com/viewtopic.php?f=10&t=1021&p=9299&hilit=Apple#p9299 In my experience, most Apple // titles will dump from the Kryoflux using the 3.3 option like IFW has ind...

Re: Unable to read any Amiga disks, please help!

It only takes one (particularly bad) floppy to clog up your drive heads. I was actually referring to your 34-pin floppy cable connector pins on the Kryoflux itself, not the power supply pins (although I understand what you mean about the Molex pin spread and that was probably a good thing to conside...

Re: Unable to read any Amiga disks, please help!

Go check out the "Bad floppies :(" post in the Dumping forum - I meant to post that here. Also, don't use the Molex from the Kryoflux. Although the feature is documented, that some documentation also says don't use it. I'm sure the board is well designed and manufactured, but I wouldn't risk stressi...

Re: Bad floppies :(

I believe when "head clog" was suggested, it was implied that your drive heads were clogged (due to a contaminated floppy). You will likely need to clean the floppy, but you will also need to clean the actual heads on your drive(s) as well. In regards to floppy media cleaning, I have used a variatio...

Re: copy-protected 3,5" DOS Floppies & Kryoflux

Ah, so that explains how that works. So really, the accuracy of the detected signal (amongst other things) is a function of the length of time since the last (set) of reversal(s) is detected. Presumably up to some agreed standard length of time, any reasonable and fit drive should detect the same se...

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

That is a great write-up. Thanks for sharing your research and results. Based only on reading your post, I would concur on your "seems to work well enough" comment; it may work many times but probably not all times.
