I'm confused. They're sold here: https://www.cbmstuff.com/forum/showthread.php?tid=60 . and you said in the thread that you recommend them?
"I can personally recommend these drives - they are what I used for developing SuperCard Pro!"

So if you `flippy mod` the drive, it will allow you to copy both side of a c64 disk without having to physically rotate the disk in the drive and therefore create 1 image for both sides at once. But if you don't mod the drive, you will have to manually flip the disk over and create two images?Exactly. A certain group of people insist on archiving with flippy modded drives "because that is how many programs were mastered". The SCP does (I think, I have never tried it) support dumping the flux from a flippy modded drive, but does not support decoding any data from the second side. But when archiving a small number of crufty unimportant flippy disks, it is simpler to just punch a second index hole and flip it over.

I *like* the Panasonic JU-475 disk drives. That is what I use. I even have a "flippy modded" version. I just turn the disk over to make copies of the backside of the disk. No need to punch a hole. These drives will read the backside when you turn off the index requirement in the SCP software. You also have to make sure that the 'DX' jumper is removed, and a jumper is on the 'EX' position. That jumper setting lets the drive ignore that there is no index pulse so back side reading/writing works.

ok. So with my ju-475 (which isn't flippy moded) I don't need to punch the hole, correct? I just need to set the correct jumper when I flip it over?
Just for clarity, how exactly do you punch that hole? do you have a jig that allows you to get it correct?It looks like it would be quite easy to damage the magnetic media if you're not careful...

Also, I don't see a `DX` jumper on the ju-475-3 drive. Is it labelled something else?

I am using a JU-475-4 drive. I have not looked at the -3 model. It may not have a DX jumper. 'EX' is the jumper that allows the reading/writing without the index mark. The DX jumper is a speed jumper (which is ignored) so it is just convenient to remove that jumper and place it on the EX position.

Ok. The ju475-3 has BX jumper - double speed. Anyway, I'm putting mine in a case, and will wire up a switch to the EX jumper.
