Unplug Your USB Devices Carefully
Whenever you unplug a USB device from its connection, make sure you are careful in doing so. The best way to unplug a device is by pulling firmly straight out of the connector. Wiggling the USB connector or pulling from an angle can cause the plug to bend or can damage (and break)┬ the internal connectors which make the device work.
This tip was prompted by having a friend bring a broken USB flash drive to me in order to see if I could do anything about it. Upon inspection, the small metal strip connectors were broken. When I asked them to show me how they remove the device, they both wiggled and pulled at an angle (quite violently).
