Another interruption to consider, especially if your project is very large, is
the periodic thermal calibration that occurs on most hard disks. Thermal
calibration, which ensures a disk is functioning properly, happens at fixed
intervals on some hard disks, even if the disk is in use. Other hard disks postpone
calibration until the disk is not in use.
Contact your hardware vendor or consult the manual that came with your hard
disk to determine which type you have. In most cases, hard disks made since 1993
will postpone thermal calibration when the disk is in use.
