4. Hard Disk Drives (HDDs) and Solid State Drives (SSDs)
Depending on the type of failure that occurs, important files might be lost when you use this equipment.
Files can be lost due to power failures or human error during operation, in addition to equipment
failures. In such cases, files cannot be recovered. To prevent data loss, save your files regularly and
establish a systematic schedule for backing up files.
(1) Handling hard disk drives or solid state drives
Precautions
• The access performance of HDDs differs depending on the equipment. Also note that the performance of an HDD
is lower at high or low temperatures. When using HDDs, verify that the access performance of the HDDs at
normal temperatures and their degraded performance at high or low temperatures do not cause problems in user
applications.
Required actions
• Do not subject HDDs or SSDs to vibrations or shocks.
• Take preventive action against static electricity due to human contact and other activities in the workplace.
• Hold the bracket or sides of an HDD or SSD. Do not touch the printed circuit board or connectors.
• When you store an HDD or SSD for an extended period of time, put the HDD or SSD into an anti-static bag, and
then store it in a dedicated box.
Specifications
• When modifying existing partitions, delete the partitions first, and then re-create them.
• The capacity and performance of an HDD or SSD might change when you replace an HDD or SSD.
(2) Backing up files
Required actions
• Back up the contents of all HDDs or SSDs periodically.
• When deleting a partition, all files in the partition will be deleted. Back up any important files before deleting a
partition.
