USB2.0 External Hard Drive Problem

Howdy,

Hopefully one of you more knowledgable guys might be able to help me with this. I took my old 30gig hard drive from my laptop and put it in a usb 2.0 enclosuree to use as external storage.

The drive is recocgnized and functions fine on my latop (XP Home), which doesn't have USB 2.0, but it is inconsistently recognized and does not perform properly on my desktop, which is new and has usb 2.0. It makes a "click and spin" type of noise and I'm thinking it might not be getting the proper power supply from the USB 2.0 connection. But I guess it could be anything.

Any thoughts or advice would be greatly appreciated.
 
Does the enclosure have a seperate power supply cord or does it draw all it's power from usb (is this even possible in this situation?).
 
The enclosure has a separate power supply cord, but it draws its power from a second USB port. There is also a ps2 to usb adaptor supplied if the drive is not getting enough power. But that hasn't solved my problem.

By the way, the desktop has XP home as well.
 
So you don't have that cord hooked up or what? I can see it getting some power from usb but not the 12v it needs. Wouldn't the ps2 adapter be for a mouse, has nothing to do with an enclosure. Do you have a link to the enclosure?
 
Thanks for the input on this most frustrating device.

The data cable plugs into a computer USB plug, as does the power cord (the power cord has a usb connector on one end and a small, cylindrical power plug on the other). The PS2 adapter actually splits the PS2 plug into a PS2 plug and and a usb plug for the USB end of the power cord. The limited documentation that came with the enclosure said that the PS2 adapter should be used if the wnclosure wasn't getting sufficient power from the USB plug.

Judging from some of your responses, the enclosure I bought might not be an ideal design. Let me know if you have any other ideas, else I'll do a little research, return it and get another on with a power supply that doesn't use a usb.

One of the most confusing things is that the drive works fine with my laptop (regualr) USB plugs. Would the power demands on the enclosure using USB 2.0 be greater?
 
I had a Belkin USB 2.0 enclosure that I ran off a USB 2.0 controller in my old computer. It had a power cord, but I believe it just ran the cooling fan. Anyway, worked great. It seems to me that you have a less than ideal enclosure.
