External Hard drive does not show up in my computer

[ Edited ]

Ok... I've been reading all the troubleshooting ideas in this forum and I've tried most of them to no avail.  In device manager in the control panel it shows my external 750 GB book is enabled and working properly.  Once I plug in the USB to my pc (running XP) it  pings as if it's recognizing I've added hardware, the hardware icon appears on the task bar and it states a mass storage device has been added etc..  All sounds good and well, except in "my computer" all my drives appears but my WD external drive.  I've had this problem since our pc failed due to a bad RAM module (I was told this couldn't happen by adding more RAM)  it did.  PC doctor had to reinstall my OS, ever since then my external hard drive won't work.  Is it due to software / drivers?   I've went into the  drive under device manager and it tell me my pc has the latest windows driver software etc..    But then I'm told by the locat Staples that this is simply a plug and play drive.... no software needed.. and I don't recall any installation CD with the drive when I purchased a year ago.   Ug... this is frustrating to say the least.. for all intensive purposes it appears the drive is working properly... I just can't access the drive via my computer or windows explorer etc..  Any help would be really appreciated.. all our digital family pics are on it. 

thanks, Doug

Re: WD External Hard drive not recognized in my computer

Blue light comes on once I plug in usb... cable must be working then right... I don't think the cable is the issue... or the add hardware icon on the task bar wouldn't appear indicating "usb mass storage device" has been added etc... this is bizarre.

Go into Disk management and see if the drive is online if not change to online.

If you don't mind voiding your warranty, you could remove the drive from the enclosure and connect it directly to your computer's motherboard. This will eliminate the USB-SATA bridge board as a possible culprit.

Firmware: 01.01A01
Serial: WD-WX71A3019645

The disk is recognised in Device Manager but not in Disk Management.
