My passport: performance

I bought a my passport essential some months ago and this was the performance of it:

now after some months have passed, I tested again and I noticed a drastic drop in performance… check the 512k test and the diskbench speed in particular

What Can I do to re-obtain the original performances?

Thank you.

PS both hard disks are deframmented properly.

Bye

The performance could vary depending of the computer configuration, the best way to determine if the passport is having performance issues is testing the unit with a different computer.

yes i forgot to mention i tried it in another computer and the performances are the same.

help please.
