Cannot Format MS-DOS Volume for Mac OS Extended in OS X
With some external hard drives being shipped in a FAT 32 (PC) format, it is recommended that they be formatted for Macintosh's native format (Mac OS Extended or Mac OS Extended (Journaled)) when backing up Macintosh volumes.
Poorly ventilated system cases can shorten the life of the hard drive
Ambient air temperatures of 95°F (35°C) or greater and poor ventilation from the smaller case designs of Shuttle boxes, LAN party boxes, racks, cabinets, and drawers, can shorten the life of your hard disk.
