5.25" PC drives

[merlinkv]

I received my two Panasonic JU-475-4, and I'm testing one ... JU-475-4A16 ...

I can make working backups from/to normal side, but I can't do it with the back side ...

Back side: I flip the disk, I set both index to ignore. Dump appears to be good, but writing back to the disk, my 1541-II can't read this side.

What's the correct jumpers config? I have:

EX - ON
GX - ON
1E - ON (bridge soldered at factory)
MX - OFF
AX - OFF
DD - OFF
TH - OFF

I'm doing something wrong?
