• This HDD unit has a finite usage lifetime. Therefore, be sure to back
up all HDD data periodically and/or prepare a backup HDD unit.
• The HDD unit's lifetime will vary, depending on the usage
conditions and environment. The above value is calculated assuming
an ambient temperature of 20°C and 333 hours of operation per
month. (HDD access frequency of 20% or less)
• To use the hard disk longer by steady operation, read the attached
"Instructions for Using the Hard Disk" carefully.

• Using the HDD unit in an environment that is excessively hot and/or
humid will shorten the disk’s usage lifetime. A wet bulb
temperature of 29°C or less is recommended. This is equivalent to
the following data.
Temperature Humidity
at 35°C no higher than 64%RH
at 40°C no higher than 44%RH
