What is the "No-Flip" mod?

[admin]

There are many drives that support just flipping the disk over. The Panasonic drives like the JU-475 series need the DX jumper moved to the EX position to allow the reading to work when a disk doesn't have a 2nd index hole for the backside. Some drives don't care (don't have a jumper setting), and some drives do not work at all by just flipping the disk over. However, since there are only two different drives that can even be "flippy modded", there are substantially more drives that work with back side reading.

You need to change the index sensor requirement when reading the back side.

I will be releasing a mod shortly that lets you flip the disk over on any drive that doesn't already work.
