Anyone familiar with these drives? I got one from ebay that was advertised "like new", appeared physically to be new, still under warranty and everything. It is 5400RPM/2MB cache. The heads don't make too much noise when the acoustic management has been set to quiet, but there is a pretty loud whine coming from the drive. Is this normal for this and other Maxtor drives? This one was made in Nov '04. Would this happen on a new/like new drive of this type or is it only a result of the drive being used a long time and maybe starting to die? Thanks.
