Re: Dumping Eye of the Beholder PC problems (copy protection)?

Yes, -k2 is the way to speicfy double stepping from the DCT program. -dd is a very confusing command because it refers to the the digital logic line level rather than the density itself. -dd0 = logic line low = High Density on normal PC drives -dd1 = logic line high = Low Density on normal PC drives...

Re: Dumping Eye of the Beholder PC problems (copy protection)?

Only use isopropyl alcohol as "the big guns" if needed. Just start with water and clean any visible spots or grime on the disk. Sometimes, tough sticky spots requires alcohol, but isopropyl alcohol has a tendency to remove oxide on flaking or scratched disks. Off hand, I would not recommend anything...

Re: Dumping Eye of the Beholder PC problems (copy protection)?

Copying using flux streams will introduce additional "noise" on the copy. So it could be a marginal read error from the original either due to minor damage on the original disk or some minor anomaly in the way the disk was written. The original may read fine in a real drive or decode with the kryofl...

Re: POLL: Problems KryoFlux under MacOS

I assume there is/was a bug report open with Apple then? What is the status of it?

Re: Installing KryoFlux in Windows 8 / 10

So just to be clear: Does Kryoflux work or not work under Windows 10/bootcamp on current Mac hardware? Is this MacOS 10.13/10.14 bug the the same or a different bug than the one that broke things in 10.11? (I wouldn't know, the only Macs I have are PowerPC :P ) Could someone post the technical detai...

Re: Panasonic JU-475-5 AKO shows up with only maxtrack=41

On double density 48tpi disks, don't forget to specify -k2 for double stepping, and -dd1 to specify low density mode. You may eventually find it is more useful to dump as a kryoflux stream file and then decode with DTC or other tools later. General advice when having problems decoding: post a stream...

Re: Panasonic JU-475-5 AKO shows up with only maxtrack=41

I'm not familiar with that specific model of drive, but with the metal shield off of the top you should be able to access the head assembly and enough of the rails to see and clean the parts that matter. It should not even need disassembly unless some unlikely specific problem is identified that nee...

Re: Panasonic JU-475-5 AKO shows up with only maxtrack=41

Head loading refers to a mechanical device that lifts the to head up when the drive is not in use in order to reduce disk wear. Those were mainly needed in drives that kept the disk spinning all the time. It sounds like your drive does not have that, although the board design supports optional circu...

Re: Panasonic JU-475-5 AKO shows up with only maxtrack=41

One possible reason is the head is hitting something as it seeks an inner track. Check that there is nothing in the way and that the rails the head assembly moves on are clean. Can you see the head moving as the kryoflux seeks? There might be a metal shield you have to remove to see the head assembl...

Can a 40-pin IDE SuperDisk drive be made to work with a KryoFlux using an adapter that converts to 34-pin?
No.

Does your IDE SuperDisk even still work? These are rather fagile devices. I've heard that putting a cleaning disk in them will destroy the read mechanisim.
