Solved *** Help *** : My external hard drive shows device working

December 4, 2013 at 20:25:16
Specs: Windows XP

I have an external hard drive that not use for a few months. Now when I plug in the device, the computer recognizes it and pop up message "new device installed", but it does not show the "path" under My Computer.
The "Safety Remove Hardware" icons show

I remember the hard drive was safety removed last time I use.


Under System -> Hardware -> Device Manager -> USB Controllers
It shows "USB Mass Storage Device". Under "Property", it indicates the device working properly, but location as "Location 0 (External )".

When I use "diskmgmt.msc", I can't see the device.

What can I do to revive my drive ?

That model is an internal 250GB SATA II hard drive.

I don't believe the Toshiba has a drive fitness test of their own so Seatools is a viable utility.

From the data Seatools generated I would guess the hard drive may not be rotating. Can you feel any mechanical motion when the drive is connected?

This could be due to insufficient DC power to actually run teh drive or the drive may just be worn out.

3.5" & 2.5" SATA hard drives use the same type of connectors, so you can temporarily connect the bare (no enclosure) drive to any desktop that has the proper SATA connections.

Be aware that when doing this, the BIOS may automatically set the newly introduced drive as the boot device. You don't want that to happen so you should enter the BIOS screens immediately upon start up to verify the boot order.

Are you using any other USB devices on your laptop?

Has this external drive previously worked when connected to the same USB port on that notebook?

Test the drive with "SeaTools for Windows": http://www.seagate.com/gb/en/suppor...

The safely remove icon is seeing your optical drive, not the external hard drive.

Is the drive a 2.5" unit or a 3.5" unit. If 2.5" try a different USB port. 3.5" units require AC power, are you connecting AC power to it?

External hard drives are actually two pieces of hardware. The enclosure is what is showing in Device Manager. If the drive doesn't show in Windows Disk Management then either the drive is defective or the enclosure controller may be defective. Try running Seatools.

If Seatools can't find the drive then try removing it from the enclosure and connecting it directly to a SATA controller to see if that helps.

Thanks.

"optical drive"? Do you mean the one with path E:? This is DVD of my notebook, there is another one "USB Mass Storage Device" with no path (no Letter assigned).

It is WD external hard disk. It is very old series with only 250G, therefore I forget its feature. It is 2.5" with metal enclosure.

I will try Seatools.

If Seatools fail, then it need remove the drive from enclosure. Any recommend for "a SATA controller". SATA connector is different from that of computer (desktop), can I buy "a adaptor" and connect the drive to a computer.

Yes, I can feel the mechanical motion when I plug in the usb, it stop very fast. This external drive has worked on my desktop previously and now fail with same symptoms. For convenience, I use notebook for testing currently.

In fact, I have a 3.5" external hard disk case. The problem is the power and SATA wire provided not suitable for this drive (the plugs are not suitable), besides it is firmly mounted on the enclosure without screw. I think I need sometimes to get out the drive and find a proper SATA connector. I hope the drive is not worn out and so this method can get back the data.

Thanks you for help, OtheHill.

Best to connect internally to a desktop. Get help with that if necessary.
