I have connected numerous 2.5" and 3" external drives to my pc via USB, and for every drive I receive the "the device is not ready" error message.
I know these drives work, as when installed as internal dives, the system sees them all ok.
I am running:
Windows 10 Pro (activated)
Intel Core i7-4770K CPU @ 3.50GHz
I have 2 drive letters available.
I have looked at very post I can find relating to this problem and have tried all the recommended tips/answers - all to no avail.
Has anyone found a definitive answer for this problem?
