Puchased a Hitachi 7K1000.C internal hard drive and idling with no partitions on it and no other actvity on the computer there is a noticable noise coming from the drive. One can also feel the drive apparently seeking / vibrating. I have never seen a hard drive like this one which is quieter when it is doing a full drive test than when it is at idle. I can hear the thing 4' away when the drive is idling.
Since the drive is new I can return it to the online reseller (with a 15% restocking fee probably) or RMA it to Hitachi. The DoM (date of manufacture) is Feb 2010 10 mths ago. Hitachi online support system shows the warranty start date as Feb 2010. A post in another forum indicates Hitachi's warranty begins at DoM and Hitachi does not extend the warranty if one provides an invoice showing date of purchase. Is this indeed the case with Hitachi warranty? If it is I will be returning the drive to place of purchase and never buy Hitachi hard drives again.
On the Hitachi warranty terms
page the only time a proof of purchase is mentioned to modify a warranty period is under
"The Hitachi Global Storage Technologies Warranty for Machines"
This would not cover hard drives but rather computers such as laptops. My interpretation is that if a extension of the warranty for a hard drive is not not mentioned in the terms of the warrant then its not applicable
If Hitachi doesn't then I have lost 10 months of warranty on this hard drive by it sitting on a distributor's shelf in a warehouse.
