Device damage  The DE is completely sealed.  Do not open the DE in the field.  (2) Service life  In situations where management and handling are correct, the life of the disk drive  is five years when the DE surface temperature is less than 48°C.  When the DE  surface temperature exceeds 48°C, the life is five years or 20,

Fujitsu Limited is not responsible for any loss of data  during service and repair.  (5) Notes on handling  a. General notes  a) Vibrations and shocks more severe than allowed will cause fatal damage to  the device so be very careful.  Be especially careful when unpacking the  device.  b) Do not leave the device in a dusty environment.  c) Because the device uses GMR (giant

                         1.1  Maintenance  b) It is recommended that you use the shock absorption cushion material and  packaging that contained the device when it was delivered by Fujitsu.  If the same packaging material cannot be used, use a shock absorbent box that  will transmit shocks directly to the device.  When using this type of box,  adequately protect the PCA surface and interface connector section.  c) Place a label showing which side is up and clearly stating the notes on  handling on the outside of the pa
