This drive has one of the highest failure rates of any modern HDD. The IBM hard drive fiasco from a little while ago is comparable. THe symptoms are an effectively dead drive after freezing and non-access to drive. Eventually the drive is completely non-functional. Do a google search and you will soon discover the huge numbers of OEM and end users who had to spend considerable time and energy pro-actively replacing huge installations of these ticking time-bombs of data-loss. Fujitsu has yet to acknowledge the problem.
