I installed a 1TB WD EARS HDD on Thursday. 99% OK but I have a question for those who may have done a similar upgrade.

When it's quiet, or if I place my ears close to the TiVO, I can hear the hard drive moving. Not the light crunching sound of reading/writing to the HDD (or whatever it is makes that sound) but more the sound of vibration from the HDD moving, being transfered through its casing and the Tivo box. Is that to be expected/common?
