Re: Bad floppies :(

There are various cleaning methods out there. The more "professional" data recovery methods usually involve cutting up disk jackets, but obviously we don't want to do that to collectible factory-original disks. I'd advise against applying alcohol to a spinning disk. As I've sadly observed, this can ...

Re: Bad* + Modified, no retries?

The underlying issue is that the Kryoflux has no way to know for sure what your disk's sector geometry is supposed to look like. As such it make assumptions that some kinds of "errors" are part of copy protection schemes and are therefore normal. Similarly, because the Kryoflux is geared more toward...

Re: Bad floppies :(

It happens that in some cases disks will start to read better after having been read a number of times. I'm not sure of the exact reasons, perhaps a thin hardly visible residue. But you have to approach that carefully because you want to avoid scratching it up. I find it invaluable to throughly clea...

Re: Thinking to buy, but have questions on writing floppies from disk images

If I recall correctly, Kryoflux only natively supports writing Amiga .adf, and Commodore .g64 files. But the HxC Disk Tool software can convert many others (I've lost track how many but it is at the top of the page below) to Kryoflux stream files, which it can then write. http://hxc2001.free.fr/flop...

Re: Two beginners questions!

Yes, Kryoflux has to deal with the same issue writing low density (40 track) disk in high density (80 tack) drives - that has to do with the nature of the drive hardware and nothing to do with the controller. So the Kryoflux or other controllers can't do anything about that. To reliably write a low ...

Re: help with 5.25" disks

Well, that is fairly specific. It seems like the system is having some problem reading the index signal on your 5.25" drive. Re-check your cables (note pin 8, which is index), make sure there is no dust or anything obstructing the drives' index sensor. Inspect the drive when a disk is in it to make ...

Re: Miller's Graphics Advanced Diagnostic (TI-99/4a) protection?

I did some more analysis on this disk. Only the first bad sector (track 6 sector 6) contains actual data, and only a few bytes in the sector are affected. Since the contents are a simple text file, it is easy to extrapolate the contents should be: 00000000 13 53 44 20 32 20 43 57-20 35 30 34 20 33 3...
