If you have a small flash drive or pen drive, you typically won’t need to attach a cord.

If you plan on using the device on a permanent basis, use a USB port located on the back of your computer. Front ports are a better option for quickly attaching and removing devices. The ports will have the USB logo next to them, which shows a circle and a 3-pronged arrow. USB-A ports are directional, which means you’ll only be able to connect the drive to the port in one direction. They have 4 metal contacts inside. USB-C ports aren’t directional, so they’re extra easy to connect.

In Windows, right-click on the drive’s icon in File Explorer and select Eject. In macOS, open finder. Then, click the Eject button next to the USB drive’s name. [1] X Research source After ejecting, physically remove the drive by pulling it straight out of the port.

Use an adapter. Search for an adapter that can connect the port type on your computer to the plug type on your USB drive. Use a USB docking station. These connect to your computer’s USB port to add additional USB ports in an external dock. Make sure the USB plug matches your computer, and that the dock features the port you need for your USB drive.

If you have the packaging for the USB drive, check the instructions to see if a driver is included for installation. A driver is a piece of software that allows your computer to communicate with the drive. All operating systems are designed to automatically download the required drivers, but if you have no Internet connection, or if the instructions specify to install the driver manually, you should do so. The driver will usually be included on a CD if manual installation is necessary. Insert the CD and follow the prompts that appear to install the driver. If this doesn’t solve the issue, you can try repairing the USB flash drive itself.
