like
a jojo :-((
the power supply is ok.
any ideas ?
Yes... This is the most common failure with the 1300 series. The head
sticks to the rubber bumber inside the HDA and can't move to find the
home track. Thus the drive spins down.
The other cure is to open up the HDA and free the head manually. If you
do this in reasonably clean conditions (not necessarily a proper clean
room) then you should be OK.
I've done that, but now it spins up, and after appr. 1 minute spins down
again and spins up, ....
Dead ?
thanks,
