I have been attempting to read some old floppy disks for my Falcon 030 before I get rid of them. My Falcon 030's floppy drive is no longer able to read them reliably. There are several floppy disks where it will list the directory, but it is unable to read some or all of the files.
I have a couple of floppy disk drives removed from PC compatible computers, so I have been attempting to use those with my Falcon 030 instead.
I know from reading these forums that the Falcon requires the floppy drive to identify as drive #0, and that PC compatible floppy drives are configured to identify as drive #1. Unfortunately, neither of the PC compatible FDDs have jumpers. So after reading some more postings, I found out that I can use a 34 lead floppy drive cable that has a twisted section. The purpose of the twisted leads is to reverse the drive identification from #1 to #0.
So I made an extension cable for my Falcon 030's internal FDD cable that has the twisted section. I have attached a photo that shows both ends of this cable. I used a crimp-on male connector to allow it to attach to the end of the falcon's internal FDD cable. After crimping it on, I used a resistance meter to verify that the internal connections are correct and match the pin numbers.
There must be something wrong with this idea, because this cable does not work at all. I tried using it with both of the PC compatible FDDs that I have.
I connected the power cable to the floppy drive unit, then attached the end of this cable that has the twisted portion into the FDD. I made sure that both cables were oriented correctly. When I powered on the Falcon 030 the drive light stayed off, and when the desktop was displayed and I selected the floppy drive A icon, GEMDOS reported that no floppy drive was connected. I powered off the unit and re-checked the original drive. Fortunately, it still worked.
So I am confused. Does anyone know if there's a problem with this approach to using a PC compatible floppy drive (one that is set to drive #1)?
Did I misunderstand how to make them work?
Thanks very much for your advice.
