Western Digital My Book Essential Edition 640 GB USB 2.0 External Hard Drive WDH1U6400N

here is what I sent Amazon customer service:
I am writing about this Western Digital 1TB back up drive, and especially the Memeo autosync and autobackup software that was preloaded on it upon receipt. My computer got noticeably slower once installing this drive, and this is software that I have to buy after 30 days. I just checked the online descriptions again, even the detailed ones, and there is no mention of software at all, much less that you have to buy it after a 30 day free trial.
You cannot stop this software once it loaded on your PC, short of removing from the computer totally. My desktop will not come up at all on either mine or my wife's account after 15 days of it being installed. I finally decided to remove this software from my PC through Control Panel, and now my computer is working much better under her userid, have not checked mine yet. At least Internet Explorer will come up when launched.

Unless you can provide alternate backup software, I want to put this HDD back in its original box and return it for a refund. It has been a big waste of my time, and I am very disappointed in Amazon's deceptive listing of its software.
