WD Ext HDD 1021 - extremely slow filetransferring (100kb/s)

Hi all,

I have an external WD harddrive, specs:

  • Model Number: WD Ext HDD 1021
  • Firmware version: 2021
  • Capacity: 2TB.

Since a couple of days the HD is extremely slow in file transferring at about 100 ~ 500 kb/s. It’s faster to download now than to copy :S.

I ran the Data Lifeguard Diagnostics from the WD site:  http://wdc.custhelp.com/app/answers/detail/a_id/940

Result of the tests is that the test itself can’t even succeed. I constantly get the message:

06-Quick Test on drive 2 did not complete! Status code = 04 (Unknown failed test element), Failure Checkpoint = 96 (Unknown Test) SMART self-test did not complete on drive 2!
Test Time: 17:12:42, January 18, 2015

 Testing on other laptops/desktops gives the same result.

What is going wrong with my HD ?

I hope somebody has a solution. There is already 1.2 TB of data on it, which I don’t want to lose…

Regards.

Ivo

Hello and welcome to the WD community.

My recommendation on this matter is to contact support for further assistance on this matter, it is not a good sign when the unit does not want to complete a test.
