Problem with Commodore disks
#1
Hi Jim,

I have a Panasonic JU-475-4APJ that was flippy modded by sncboom2k.
I cannot get a single image to work using my Supercard Pro, no matter what I change the setting to.
I am using the same drive with a KFlux card and have no issues.
I literally just unplug the KF, make no changes, then plug in the SCP.
KF image works, SCP doesn't
I am imaging Commodore 64 disks
What am I doing wrong????

What disks are you trying to image? If they are commercial, you should be using INDEX mode. Otherwise, data disks have to be copied/imaged with SPLICE mode.

Thanks for the reply, they are commercial, orignal disks.
I can backup most of them with nibtools etc, but have never mamaged to get a single working image from SCP.
It must be something I am doing wrong, or my card is dead?!

Good question.  Run the media test in the Disk Utilities Menu.  That will read/write to a disk and test the drive and SCP hardware.   It could be something as simple as your disk drive heads are dirty.

You can make an image file (.scp) of a disk using INDEX mode and send it to me (data @ cbmstuff.com).  I can look at the image file and tell you what is wrong.

OK, I will do that and send you an image.
Thank you.

Yep, your SuperCard Pro is bad. Take a hires picture of the board - in particular of the area with the Huey and Duey chips. I am guessing that you plugged the cable in backwards (probably to the disk drive) at some point and damaged Huey.
