One of our clients have experienced issues with Fujitsu hard disk drives of type MHZ2080BH. If the surrounding pressure increases, the hard disk drive fails.
We have supplied a number of Fujitsu MHY2080BH (2.5" SATA 5400RPM 24/7 ESW.) Does anyone have any knowledge or experience with these? What are their differences or similarities? Are they more or less likely to fail than the other type?
Computers are placed in pressurized cabinets as the equipment is placed in an Ex zone. The pressure is not particularly high, but must be higher than outside the cabinet. Hard disk drives tend to fail during the purging phase.
