Hello,

 I have a WD-10EAVS 1tb USB drive and it is very slow. Sometimes I think it is just sleeping. The access time is terrible. I wouldn't recommend it to anyone.

 I have a Seagate 1tb USB drive sitting right next to it and it is a cheetah compared.

I also have had drives "disappear" and a complete shutdown and restart usually works.

Anyways, good luck...

No good deed goes unpunished ...
