I'm having the same problem with 2 of my 500's and was wondering if the drive jumpers are in the right place
2 drives both matsushita
The first one is a JU 253-03t (any idea were I can find the recommended jumper settings?)
and the second is a JU-253-031P this one probably needs cleaning i get a read error message but I haven't a clue how to clean it properly.
I have a panasonic drive that works in both.:confused:
