4. HARD DISKS DRIVES (HDDs) / SOLID STATE DRIVES (SSDs)
Depending on the type of failure, important files may be lost when you use this
equipment. Files can be lost by power failure and human mistakes during
operation in addition to the failure of the equipment. If such a situation occurs,
the files cannot be recovered. In order to prevent data loss, make it a routine to
save your files and establish a systematic schedule for backing up files.
(1) Handling the Hard Disk Drives or Solid State Drives
<Precautions>
・The access performance of the HDDs or SSDs differs depending on the equipment. Also
note that the performance of an HDD or SSD is lower at high or low temperatures. When
you use HDDs or SSDs, confirm that the access performance of the HDDs or SSDs at
normal temperatures and their degraded performance at high or low temperatures do not
cause any problems to the user application.
・Regularly replace the HDD or SSD by referencing "APPENDIX HANDLING
REPLACEABLE COMPONENTS".
<Required actions>
・Do not subject HDDs or SSDs to vibration or shock.
・Take preventive action against static electricity due to human contact, and due to other
activities in the work place.
・Do not touch the printed circuit board or the connector of an HDD or SSD. Failure to
heed this instruction might result in damage to the HDD or SSD.
・When you store an HDD or SSD for a long time, put the HDD or SSD into an anti-static
bag and then store it in a dedicated box.
<Specifications>
・When you modify existing partitions, delete the partitions first and then re-create them.
・The capacity and performance of an HDD or SSD may be changed when you replace an
HDD or SSD as a component.
(2) Backing Up Files
<Required actions>
・Make sure the contents of all HDDs or SSDs are backed up periodically.
・When you delete a partition, all files in the partition will be deleted. Before you delete a
partition, back up important files you need.
