Does this happen to you only on one USB or on all the External Hard Drives?

Hi,
Have you tried to restart the machine and see if that helps ?

Are the devices OK on another PC? I would run chkdsk on c in case explorer is corrupted. Have you tried all USB ports?

Do you "unmount" your external drive before unplugging it, or do you just unplug it?

Here is a post where I discussed the problem caused by unplugging an external USB drive without first "unmounting" it, and how to fix the problem caused by doing that:
