Problem: flash drive(s) going offline/'not recognized'
I'm experiencing a problem with a few of the 3.0 Sandisk flash drives very periodically not being recognized by the laptop.
The backup software will throw an error to the effect 'drive letter 'x' does not exist'. If I unplug and plug the particular drive the computer recognizes the drive until the next time generally 1 or 2 days later.
Are the blue LED's that are adjacent to each USB port supposed to be always on when a device is plugged in and is recognized or is the light only on when there's activity of some of sort or?
