Re: Kryoflux Flippy Disk Preservation Commands

Could it be that you used different density line flags for g64 and d64 encoding? With the example command line in your third posting above you used -dd0 for creating g64 files. Using -dd1 may change the output... Great question! I've tried using both -dd0 and -dd1 from the same KryoFlux stream. Eit...

Re: Flippy Disk Confusion Between Commodore 1571 vs 1541 Drive

Actual 1571-mode disks are very rare. Even most 128 software was only distributed in single-sided format because you couldn't assume a 128 owner used a 1571. I think I've only see one or two actual double-sided 1571 mode disks.

Re: G64 demo "Bounty Bob Strikes Back" problems.

Due to how the timing works, I bet it likely only works on an original 1541 and not a II.

Re: Power Supply kills drives ?

I assisted the lady at Emory with some archiving once a couple of years ago and noticed that the 12V and 5V were reversed on their power supply, which burned several of their drives. They said the connectors fell apart and they thought they put them back together correctly.

It's something to check.

Re: Apple II disk Grrr.....

I only have the disks- If the owner has materials, he didn't send them and may be able to photo them for you.

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

This works great. I was able to convert a regular 800k Mac disk and write it with KF. Boots fine on a real SE. Some of the disks I found (official System 6.0.8) were 820k and the tools would not process (checksum error). However, I was able to convert from dsk to dsk with CiderPress and then it was ...

Re: Apple II disk Grrr.....

Rakki- I will take a second look at those disks you mentioned to be sure they aren't salvageable. Also, I took some group pics so you can see the labels.

Re: Apple II disk Grrr.....

Many of these disks are too far gone. Cleaning won't help most of them- they have banding from where the coating has come off the disk. Some of the Apple disks are from 80, which is getting on towards 40 years now.

Re: Apple II disk Grrr.....

I am imaging a large batch of original Apple II SSI disks. All tracks show as unformatted on all these disks, so really nothing I can do except raw dumps at this point. I tested they were Apple II- they boot fine in my GS. I can also take a normal DOS 3.3 disk and DTC will see that, so I guess that'...
