Re: help writing bootable Osborne disks from stream files

So in other words, it sounds like a drive speed issue. Check and adjust the A drive's RPM speed. Check for any damaged motor control components.

Re: TEAC FD-55BR doing weird noise when calibrating with Kryoflux

If you know what the maximum tracks should be set at, you don't need to do that.

If you suspect anything isn't plugged in right, the calibrate test is indeed an easy way to check. As you gain confidence in the hardware setup, you probably will eventually just skip that unless a problem arises.

Re: TEAC FD-55BR doing weird noise when calibrating with Kryoflux

On a decently manufactured drive such as a Teac, no it shouldn't damage anything. Supposedly on some very, early or very cheaply manufactured drives there is a slight risk. But I have never run in to a drive that could be damaged like that. Keep in mind that on IBM PCs, any piece of software could e...

Re: TEAC FD-55BR doing weird noise when calibrating with Kryoflux

Right at the end of a calibrate, there may be a very momentary unhealthy sounding noise as the head tries to step behind the last possible track, hitting the stop. Also, some drives are noiser than others, so the noise will vary from drive to drive, even of the same model.

Re: help writing bootable Osborne disks from stream files

First of all, what kind of drives are you using for this? You can't use an IBM PC style "1.2mb" (80 track 96tpi drive) to write a disks for use in a "360k/180k" 40 track 48tpi drive. (Technically, if you degauss the target disk first it should work, but that can be a headache) Se...

Re: Is this a normal dump?

Try formatting a DSDD floppy disk as "quad density" using the good drive (80 track, 720k format). That will be close enough. Locate any 720k 3.5" floppy image .IMG file, drag it to HxC, export as Kryoflux format, and write that in your good drive, make sure not to enable double steppi...

Re: Is this a normal dump?

What exact model of drive is this?

All IBM PC compatible 1.2mb drives should be able to read 360k disks. Did you TRY a 1.2mb disk in that drive? I would expect the same behavior where all tracks are off by one.

Re: Atari ST help

What tool are you using to make "ipf" files? What kind of disk are you trying to duplicate? It is my vauge understanding that Atari ST use MFM sector geometry similar to IBM 720k disks, and therefore should not be much problem to duplicate standard data disks. Many games and applications, ...

Re: Write and Read Back Issue...

I'm a little confused as to what you are trying to do. If you just want to format DOS disks in an 8" drive, you don't need any really special softare as long as: You either have an 8" adapter that creates the T43 signal, or a drive that does not require it. Are using a high density control...

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

Oh, in that case ImageDisk format would not work. It assumes correct head and track numbering. It fdoesn't look like HxC can import an .IMG like that.

Were these systems designed to treat each side as two different drives? I have seen some 8" drive with that hardware option.
