Sometimes when I switch on my Classic the hard drive starts to spin up then suddenly slows down like the power's been cut, it makes a noise and then starts to spin up again... and would go round in a loop if I left it on. xx(

At other times it just spins up and everything's fine :b&w:

I've tested the voltages on the external drive connector and get 5 volts on pin 6 and near enough 12 volts on pins 7 and 8.

I don't know what to try first, the drive, or caps on the analogue board? and would like to know if it's a "Classic" case of one or the other.

Any advice welcomed.
