Tom says his computer thumb drive is very hot. Should he be concerned? Leo says thumb drives can get pretty hot and the tolerances are designed to be that way, but most modern electronics are designed to stay under 100 degrees C. So if it's so hot that you can't touch it, then that can be cause for concern. It'll make the drive less reliable and over time, it'll wear out prematurely. But it's within normal limits for the drive to run warm or hot. Just not scalding. Especially when it's not doing anything. That's when Leo would throw it away.
What Leo advises copying the data off it and plan on a replacement, cause it's going to fail sooner or later.
