Hello,
I have an x68000 XVI that was still working perfectly a few weeks ago, but since yesterday,
my drive 1 no longer accepts my discs: it ejects them directly. Occasionally,
it keeps the disc but can't read anything from it.
Or, more rarely, it can read them as if nothing had happened (but only 1 in 100).
What can I do?
The compact XVI or regular tower? The compact 3.5" drives have surface mounted caps that need to be replaced as they are known to leak. There are several, one of which is hard to find and get to.

Regular tower.
If you disconnect the ribbon cable of the drive 1 you can replace it with external FDD my emulator (available soon again) :

Is it sufficient to merely disconnect FDDs in order for the externals to take 0,1 assignment? I always thought jumpers needed to be changed too.

If you disconnect both internal FDDs (for disconnecting I mean detach the ribbon cable from each drive) and set jumpers of each 'FLIP-FLOP' emulator as '0' and '1', you will obviously have emulators acting as '0' and '1' drives.But in my previous message I actually meant that you can replace one faulty internal drive ('0' or '1') with one 'FLIP-FLOP' emulator (set as '0' or '1' with jumper) but you have to detach the ribbon cable of this defective internal drive.

Sorry, when I said "jumpers" I was referring to the internal jumpers inside the computer itself, not those on the FLIP-FLOP boards.
That said, I've now learned that you can disable internal FDDs by disconnecting ribbon cables and then any externally connected floppy emulator can function as drives 0 and 1 (as long as they're configured to do so, which in the case of FLIP-FLOP is achieved via jumpers).
Thank you for the clarification :)

If you want to keep the internal FDDs along and se the emulators as '0' and '1' then you must change to '2' and '3' the jumpers of the internal drives

Exactly, you can disable internal FDDs by disconnecting their ribbon cables and then set the emulators to '0' and '1'.Did you try it?

You're welcome! ;)

I have not. I may give it a try on my secondary X68000, which is an XVI unit. Both of its drives are very healthy, but it's wonderful to know I have a backup (i.e., emulator) solution without obtaining another FDD switch kit from Japan (which has been challenging, and I've only successfully done ONCE).
