The program's options allow you to establish the unit of measurement in degrees celsius or degrees kelvin. You can also set an alarm to go off if the temperature goes above a limit that you have previously established.
One of the great things about using DiskAlarm is that it requires no installation. The program barely takes up any space, and you can take it along with you on a portable drive and run it from anywhere.
DiskAlarm is a very useful app that can help prevent your hard drives from fatally overheating.
