The Kryoflux board is powerd via the usb cable. You may also download the software from kryoflux.com ...

Re: Bad sector recovery using STREAM files?

Okay side 0 looks great so for me (1,44 Mbyte MFM DOS-Disk as far as I can see). Have you visually inspected side 1 of the floppy surface? Could be spots of mold there. If so try to clean it with a bit of water on a q-tip before you use any isopropanol or similar! You may just open the slider by han...

Re: Bad sector recovery using STREAM files?

If all tracks are bad it rather looks like choosing the wrong format to decode the stream for me. Can you upload the stream data anywhere to have a look on it? You may also load the stream to the hxc-tool and have a look to the grafic analyze view. There should be a visible pattern at least. https:/...

Re: Timeout while waiting for device initialization

You mean the green LED does not go off while you press the reset button!?

Are there any USB-Hubs involved (even inbuilt)?

Did you ever tried the kryoflux hardware on another machine (just to sort things out)?

Re: HP 86B Disks

The linux file command detects the image as lif (that means HPs "logical interchange format")! I can see the directory and copy files with hpdir command: FILE NAME PRO TYPE REC/FILE BYTE/REC ADDRESS DATE TIME TENCODE DTA8x 65 256 16 CARDFILE BAS8x 121 256 81 UTIL/1 BIN8x 15 256 202 QCODE DTA8x 65 25...
