Connected wrong power cable to external HDD

Specs: Windows Vista
I connected my laptop power cable to my external hard drive and now there is no power to the hard drive. My question is did i ruin it or can I take it out of its case and install it in to a computer?

I suspect that there may be a small fuse that one might be able to replace it you want. It may be a common one or may be oddly labeled like R1 or L1 but have someone who knows electronics look at it.

In most cases you should be able to at least try to replace either the external housing with some smaller adapter or enclosure. Or you can try to put it in a computer.

Some external NAS may be linux formatted. I assume you mean a usb external box.

Why did it take me over a year to phone in a problem to ATT?

Yes it is a USB hard drive. I tried to hook it up to my computer and then it would not start. i unpluged it and then it did start. So then I hooked it up while the computer was running and it shut off. Just to clarify it was only when I hooked up the power cable that it did this.

So you are saying that the drive works when only plugged into a usb cable but not when you then plug in the ac power?

No Sorry about that. I read it over after and it didnt seem too clear.
So when i hook it to my computer the computer dosent work and if the computer is already on it will shut the computer down when the ac cable is plugged into the hard drive. And the hard drive dont work at all externally. That is why im putting it in my cpu to see if it will still work.

You may have damaged the extenal drive when you used the wrong power adapter, That is a common problem wrong type of current, wrong polarity or wrong voltage. Mostly bad labeling you can't tell which adapter goes with what device. Frequently the manufacturer of the adapter is different from the device.

Thanks I thought that was the problem. But I was hopeful that it was only a fuse in the case of the external hard drive that i blew.

You most likely fried the HD. Laptop power supply is putting out more volts DC than an external HD and I doubt you can fix it yourself. Someone may be able to or at least obtain the data off the HD if you absolutely have to have it.

No I dont need the info on it just thought that it was a cheap way of reusing the old HD thanks for the info.

For future reference - Label both the power adapter and device with a model number and voltage and current rating so that they be matched if separated or need to be replaced.
