power cables for external hardrives.

[djfunknukle]

I have accumulated numerous external hard drives, mostly seagate and WD. unfortunately, I've lost track of which power cords go to which HD. Are these cords pretty much universal, in that if they fit, they work fine or is there something else i should be looking for on the power cord to match it to the HD?

On the actual external drive part, it will tell you the voltage and polarity you are looking for. You match this up with the info on the ac adapters' label.

No.

Your first problem is fit. Is amazing how many coax power connectors sizes there are.
