Re: How to use the Kryoflux system to format a blank floppy disk ?

The ONLY thing that a kryoflux can write (with a couple of exceptions) is a flux stream file. One of those exceptions is their IPF format, but I'm not aware of any end-user accessible way to create one. For example, if I wanted to write a blank 360k IBM PC disk, I would use an emulator to create a b...

Re: Don't forget the terminator

Actually, it is possible I might have had an unrelated power issue. Technology is down to the molecular/quantum levels these days, yet "modern" production can not produce molex connectors that reliably make contact. On 5.25" drives, no power on the +12 volt line may cause the head to ...

Re: Is this a normal dump?

Looking at this image, there appears to be a drive alignment problem. All of the tracks are offset by one. Track 0 is where track 1 should be and so on. Check the operation of this drive using a good, known working, factory pressed 1.2mb original disk like a driver disk. The problem could be as simp...

Don't forget the terminator

Just documenting this in case it helps anyone else (others probably already know this, but this is the first time I personally ran in to this on a KF). I was testing a pair of Panasonic/Matsushita JA-551-2N floppy drives with the Kryoflux. The one without a terminator refused to move the drive head ...

Re: Test image for an 8" drive?

Glad that worked for you. I was going to suggest reconstituting an image with HxC. I usually export to imagedisk format and re-import, but in this case Imagedisk format won't work because HxC always assumes IMD files are made at 300RPM so the resulting image is only suitable for 300RPM drives, not 3...

Re: Test image for an 8" drive?

I'm a little confused here, so this is what I am seeing: disk 1 shows 1024 byte sectors,tracks 0-76, double sided MFM. dump looks ok. I don't know what file system. disk 2 same disk 3 same disk 4 same disk 6 same (the file disk6_77.1.raw looks damaged, but that would not have anything in it) disk 5 ...

Re: Sublogic Flight Simulator Scenery Disk Format (IBMPC)?

At a glance, dumps look perfect. It is copy protected. The protection is a mix of sector sizes. This can NOT be stored as an IMG file. It might be possible to reduce this to an ImageDisk format (which can store mixed sector sizes), but that would have to be tested to be sure. It should be possible t...

Re: How to deal with bad sectors on 800K Mac floppies

That directly controls the logic level of the Density Line to the floppy drive. Usually setting Logic Low = High Density and Logic High = Low Density. Confusing, yes, but a few drives from non-IBM PC compatible system actually REVERSE their logic level signals to that line, hence why Kryoflux only r...

Re: Determine 8" Disk Format

I don't have mine hooked up at the moment. As I recall it would step to 79 or 80. But 8" drives are all officially 77 track drives. Anything past that is just extra because the drive's microcontroller or physical stop hasn't stopped the head from moving. If I recall correctly, the Kryoflux cali...

Re: Determine 8" Disk Format

I've also got an M2896, it has worked well for me. At a glance, that dump looks like 100% noise. Check that the drive heads are clean, and that the head is engaging when the drive is activated. Hopefully your disks have not been degaussed. Until the issue is resolved, I'd recommend using the GUI too...
