Stop working

This was a terrific USB drive until it stops working. Now it's just a piece of rubber with useless electronics inside.

Fast; High Capacity; Portable

Unreliable

100% failure rate.

I have had two of these drives, (two different people/computers using them), and both failed completely, registering as an external drive when you plug into a Win7/8 machine but not being available to copy files to them. 100% failure rate with relatively little use.
