Hard drive maker Seagate has revealed that a number of its drives are becoming inaccessible when the system containing them is started up.

The offending drives were all manufactured in December 2008 and come from the following product families:

Barracuda 7200.11
DiamondMax 22
Barracuda ES.2 SATA

Seagate says that even though the data may become inaccessible, it has not been lost and can presumably be retrieved using data recovery services, which Seagate will pay for.

Good News!
Seagate have a New Patch on their site to fix a previous patch that did not work (if you follow me?)
Which should restore Functionality...Hopefully
