Hmm, sounds like defect hardware, so there is also probably no timing issues with the fujitsu hard drive. So lets just handle it as a regular hardware defect to be fixed under warranty, please send an email to [email protected], including a clear and detailed description of the problem, including a reference to your communication with me, somebody will then take care of it.
