WD 640 errors

[xev11]

I am having trouble with my WD640. It is sometimes disconnecting when the system is running and sometimes isn't visible upon startup. It is my secondary drive, but still have important info.
I need to disconnect and connect to make it visible, and that doesn't always work the first time.

Under Health Tab in HDTune Pro, Current Pending Sector has a warning status.

I got a WD 1Tb drive to try to image everything onto it, but both DriveImage XL and Paragon Backup & Recovery failed.

Run WD Data Lifeguard for Windows. If it gives you error with # contact WD for replacement with that #. You should always run diagnostic program offered by the maker of the HD.

Saving contents to another drive is a good first move. SEE Acronis True Image, same page.

Sounds like the drive is failing. One easy thing to check for are bad cables, so replace the power and data cables and see how it goes.

Am I right in saying that you had just one copy of your data and that you're trying to copy it now that it's giving problems? If so, then that's the wrong strategy.

Keep at least two copies of your data on separate hard drives at all times and back them up regularly, say once a day or perhaps more often. Otherwise, it's simply data that you haven't lost yet, as you're finding out.

try a low level format

after you save your data on other drive.
It might fix it if is no physical damage block.
Have a try
