How do you take this thing apart, dont see any screws, just pry the top from the bottom? Not sure why just taking the top off would help, plus, how do you plug it in any other way besides USB?

Kurrent: Yes, drive worked in another computer, a desktop, just plugged in the USB and was recognized. Plugged into the case.

Also, had a USB card reader that used to work (just like the WD USB drive), and now the computer does not recognize it.

How many USB ports do you have? You may have a faulty port. Is this a front panel port on a case?

3 ports on the laptop, I dont think it is faulty, every other USB items I have works, except this USB drive and the USB card reader.

Have you tried using a 2 port USB power splitter cable?

I dont have a powered USB hub...but dont think that will solve the problem, I think there is a problem w/ the usb hub. How could I find out? Works w/ mice, but not w/ this particular type of WD external drive, but worked with some others.

Since the drive works on other computers. This is a sign that your laptop doesn't supply enough starting current to allow the hard drive and it's SATA to USB adapter to initialize properly.


A special cable like this that supplies power from 2 USB ports may help.

Thanks Kurrent...just confused, why would it work on a nearly exact same WD USB drive?

Also, I have Vista, and under Device Mgr, it is seeing the USB drive.

OK, sees it when I try to Safely Remove...believe it is just not assigning it a hard drive ltr.

It's just the slight differences between the 2 drives. USB 2.0 wasn't designed to power 2.5" hard drives even though it works most of the time. I have 8 generic external hard drive enclosures with old laptop drives. Two of them have Seagate drives that won't work off of just USB power alone. But they work when powered by a hub with it's own power.
