we got a new pc w/ a 500gb seagate and it was quiet and we installed vista on it. Then we transfered all the file from our old drive that had xp on it. The seagate then became noisy after the transfer. Then, we got another hitachi 500gb drive and put vista on it and it was quiet, then we transfered all the files from the seagate and the hitachi became noisy. So my question is, can the file transfered i did be making the drives noisy by doing somethting w/ some file that is not compatible w/ vista? Thank you so much.
