FRU P/N 72X8523
EC No. A58560
When I went to to start up my 8580s, I found that all three of my floppy disk drives would not read diskettes. Two of them are manufactured by Mitsubishi. Before shelving them, I decided to pull off the covers and poke about. I found several surface mount electrolytic capacitors that were either open or had very high ESR.
uccessfully repaired both
units by replacing the capacitors indicated. The third unit is
by Alps, and I haven't looked at it (yet).
