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...

Re: Newbie: Where to start to read with which I have to start with?

BTW: There are drives that have jumpers which (if set correct) let them ignore the index pulse an keep rotating and sending data even if there are no index pulses at all. The Mitsubishi MF504B and MF504C behave this way if you remove the jumper RD for example. Theese drives where recommended for the...

Re: Newbie: Where to start to read with which I have to start with?

You're absolutely right. A second light barrier at the correct position would be fine. Unfortunatelay I have never seen a drive which offered enough space at the correct position. Usually there is some mechanic or the pcb located in that position which can not be removed easily...

Re: Newbie: Where to start to read with which I have to start with?

It's not the write protection notch but the lack of a second index hole which calls for a flippy drive! C64 and apple II drives didn't check the index at all, but every common 5,25" pc drive needs it. If you flip the disk and there is no hole for the photocell the drive will stop the motor immediate...

That was the common connector for 5,25" drives...

You need a standard floppy cable like this one:

Re: Dumping flippy in non-flippy drive using fewer than 2 passes?

That's actually my usual workflow with really bad looking disks! I do a format guided Raw dump of all tracks first. After that I atempt a retry to only the bad tracks to another target directory. If any get good reads after several retries I copy them to the first directory replacing the former bad ...
