I would advice you not to buy that HDD. Everyone I know has had issues with WD external drives. Myself included
I would suggest
This is built to be rugged. I have one myself. I use it as my travel HDD (Military Drop Standards , triple protection)

I am also using this

I haven't had any problems so far and it comes with a 5 year warranty. But I don't know if I can recommend this as I don't know anyone with the same disk.
