    Ok, not familiar with these external drives. What is that external plug that hangs out the back of the drives? When I got my three drives, I assumed they were missing the power supply.

    Indeed, the adaptors just need to be tested now.

    It's just a chassis ground wire that connects to the computer, it's seems that most owners had them added for some reason. On my ex the ground wire is connected to one of the expansion slot screws.

    I wonder if there was some sort of chassis static charge buildup in the external floppy drives that this mitigated.

    Electrical noise (e.g. ground loops) can raise havoc in disk drives. Maintaining a good chassis ground throughout is a way to avoid the problem.

    Considering there's already 8 ground lines in the original cable design, it does seem odd that this extra chassis ground wire is needed.

    Ok I've paid the post office a visit and crunched the numbers and the Adapter is $19 USD + Shipping which is $5 USD (covers my PP fees too) so total cost is $24 USD shipped to USA / Canada. Delivery time should only be about a week to the USA - I've heard to Canada is really really freaking slow so apparently anywhere from 2-8 weeks depending on where you are is normal.

    Anyhoo, still waiting on my leviton Power plug (which is due next week) to test the Adapters..
