Well, I don't have a great explanaintion for this, but now they are both working!

I took the logic board out of the 1st one, looked it over, blew off just a little bit of dust, put it back in and it started seeking immediately.

The screen was blank, so I moved the connector ever so slightly and it came on with the desktop image.

I am assuming I must have reseated a connection that wasn't working, unless it really as the dust.

The frst drive obviously needed a once over since it was jammed, but I think my primary issue was the Sony disks.

These 400K drives must be a lot pickier than the 800K. These same Sony disks are no issue in my other machines.

:b&w:
