*1: Ambient temperature should be measured at point 10 mm away from the nameplate of the drive. If the
maximum operational ambient temperature cannot be measured at a point 10 mm away from the
nameplate, a substitution method is stipulated in the table below.

*2: In case of the maximum wet bulb 40°C , the drive should be
packed in HDD package box with ESD bag and desiccant.
Please see specification 5.1 Packing for reference.
If the drive is not packed in the HDD package box with ESD
bag and desiccant, maximum wet bulb 29°C is applied.
