Solutions to problems:


WD Western Digital Mybook

My external hard drive suddenly stopped working and disappeared from my Hard Disk Drive lists. I feared I had lost all the data, but luckily it was still all there and I managed not only a complete recovery but a fix for the disk (touch wood!). The drive letter was missing and when I checked in Computer Management, I found that the disk space was unallocated. I found the following solution, it turned out that for some unknown reason the partition table had gone missing or was corrupt:

The software I used was Testdisk from

The situation with a "lost" hard drive typically arises after Windows has been reinstalled or when a slave/external drive is moved to another computer.
If the drive/partition shows up in Device Manager and Disk management, but NOT in "My Computer", chances are that it is "only" the partition table that is missing or corrupt.

You can use a freeware program called TestDisk to repair the partition table and get access to your data again.
TestDisk will not change or delete any of your data if you follow the instructions below.

This guide is written for Windows, but you can use TestDisk with Linux and Mac as well.

Try this to repair the partition table:

Download the Windows version of TestDisk.
Unzip the downloaded file to your C: drive.
Open C:\testdisk-6.10\win > double click the "testdisk_win" icon.

The program runs in a command window and doesn't have to be installed.

Each of the steps (A, B, C etc) below corresponds to a new TestDisk window.
Use the keyboard's arrow keys to navigate.

A. At the first window, select “No Log” and press the <Enter> key.

B. Select which drive to analyse, choose “Proceed” and <Enter>.

C. Select partition type – Intel if it’s a PC then <Enter>.

D. Select “Analyse” then <Enter>. The drive will be analysed.

E. Select “Quick Search” at the next screen, then <Enter>.

F. Press “Y” if the partitions were created under Vista – “N” if not.

G. TestDisk should say “Structure OK”. If so, press <Enter>.

H. Select “Write” and press <Enter>.

I. Press “Y” to confirm.

J. Press <Enter>.

Close TestDisk and RESTART the computer.
The drive/partition should now be fixed and your data available again.

Hopefully, it should all be working fine again!
