This product is excellent! It works perfectly and quietly and is better than I imagined!

Drive not functioning after 2 months. Went to their website, followed their recs re trouble-shooting. Worked 1 week, then not functioning again. No replies to my follow-up requests for help. Stay away.

This drive failed after one year. I lost a lot of personal and financial data that is not recoverable.

It was not abused. Sat on a desk for the most part. No power outages. It died during a write access for a financial program.

This is the second WD drive I have die on my in a year of use. (I had blamed myself for the first one, but maybe this is the just the way these drives are built.)

Back to paper for the financial reports. They don't need batteries.

These are nice units and easy to use. One day when I turned it on it just disappeared. I tried everything but it was still not seen in My Computer or Explorer. So I formatted it. If you format them to NTFS and assign a drive letter before using it you shouldn't have the problem of it disappearing.

My WD drive failed after a couple months...never did any damage to it. One day, it wasn't recognized by my PC and when I powered it down and turned it back on, the clicking noises began.
