I have this ProApp 20S external hard drive for my 1984 Macintosh Plus All-in-One. When I plugged it in and turned it on, it began to smoke profusely after 10 minutes or so. I opened it and noticed it had 4 RIFA capacitors, and at least 1 was blown. I changed all 4, light on the switch goes on, and I hear a little "click" coming from somewhere on the board. I narrowed it down to that blue coil with the number 216-03 marked on the top. Occasionally that coil will really act up and make quite a bit of noise. I hear absolutely nothing from the hard drive itself. I'm presuming that the board is attempting to start the hard drive but is unable to do so. I should hear the hard drive spin even though it's not connected to the Mac, correct? From what I've read it could very well be seized. Is it even worth replacing it's hard drive? I can't find the exact model, and they are not cheap. I have other options (I own a FloppyEmu), I just enjoy restoring things if it's at all possible and economical. I haven't connected it to the Macintosh because I just restored the Mac to working order and don't want to cause issues. Is it safe to connect without causing damage to the Mac? Pictures:
