Good but unfortunately vibrating disk!

In my Thinkpad exactly the same hard drive was installed, only the 250GB version.
Since I was very pleased with this I've then 500ter ordered because
Encryption I did not want to miss and with this feature was the selection of plates not very big.

Although the specifications of the 250 and the 500, according to Seagate match (even the weight is the same. What made me suspect that in the small simply a platter is less driven).
Creates the 500 model strong vibrations which are clearly audible, but felt in the fingertips.
If the laptop on a large work desk, the noise is enhanced.

At first I thought it was a failure and had submitted the plate twice for repair.
she was gestauscht. But the 3rd model was hear / feel to no improvement.
Amazon has but withdrawn without hesitation!

This makes the plate for me unusable for my laptop.

I have to mention that I am As for what sounds quite sensitive.

Astonished I was also the small model has no vibration and the volume is very good.

Only those who are very sensitive to noise, I can recommend the plate, because otherwise it is quite good. The encryption also does not speed.
