Re: Texas DS990/1 Dump

There is also a problem with the drives speed which has much flutter! I guess the drive needs a proper service including a change of the belt...

Re: convert 360ko dump with a 360ko drive

Because of another issue I just did study the manual again and found that the -e parameter sets the last track for the reading but -oe sets the last track for the output!

So -oe39 should do the trick....

Re: Floppy disk/drive curiousities

The tripple floppies have a totally different approach with a complete different hardware! They don't use an index hole for example but an index track with a separate head giving exact sector positions, similiar to what was done with hard sectored disk decades before! There are also other formats wh...

There is an other GUI tool for writing available in the download section at kryoflux.com:

Re: Not working with one of my computers.

Is it possible to write with the shell? I do not find anything about this possibility...
What do you mean with "shell"? Didn't you do exactly that in the first picture you posted?

Re: Oh dear, did I fry my KryoFlux?

I wouldn't say that all SFD-321B are risky, but the rev WT-04 certainly is! I once got a bulk from ebay (5 pieces because they where cheap and there was an easy modification to use them in the amiga) of which 3 went dead while copying or formatting a disk (intense stepper use)! On one of these board...

The schematics are already on your computer! There is a directory called schematics in your kryoflux installation. The circuit in question is IC3...

Re: Oh dear, did I fry my Kyroflux?

You should measure the pins with the negative probe connected to GND. That's the black wires on the molex or the metal shielding of the drive. To be save, you can measure also the output voltage of your supply. It should be 12V on the yellow wire and 5V on the red one (negative probe connected to on...

Re: Oh dear, did I fry my Kyroflux?

That looks as if you are feeding voltage from the drive into the kryoflux board! I would disconnect the drive from the board, power up the drive alone and look for the pins 8, 26, 28, 30 and 34 on the drive's connector. There shouldn't be more than 5V! Later Samsungs SFD-321B contain four diodes lik...
