Nope. You got me. Here's a check list:
Is this an FDHD or upgraded SE?
What OS are you running on the SE?
Are the disks locked?
Do the disks work properly on the internal drive?
Do you have another external drive to test on the SE?
Do you have another compact to test the 400K drives on? (we need to rule out the SE)
OA-D34V-22 is the latest 400K drive mechanism, which should work fine with an SE. If this were an original 64K ROM, I might wonder if it wasn't an incompatibility with the ROM and later eject mechanism. But the latest ROM code should be in the SE.
Pina suggests one problem might be a bad external floppy filter, but if other external drives work, then that's not the issue.
This is really an odd one. It's in long enough to mount, but immediately ejects. What triggers the ejection mechanism on a 400K? Hmmm. Is the SE otherwise fully functional? No sticky mouse or keys?
When you look inside them, do you see two red LEDs, or just one?
