Hi all

I have a couple of Oki 3305BU 1/3 height 5 1/4" drives.

On startup the motor spins and the heads load, but the heads don't 
move. Also, my BIOS tells me I have a drive failure.

On taking them apart for a bit of a lube I noticed they have EPROM 
8748s inside. Could this be the problem, EPROMs lost data? This would 
be a first for me, I have EPROMs from the seventies which are still fine.

Anybody familiar with these drives?
