To get around this problem you need a powered USB hub. Unfortunately, the Pi cannot power some external drives. Many modern desktop PCs and laptops supply a higher amperage than the 0.5A specification to their USB ports to support devices such as portable hard drives. My old Samsung G2 Portable 640 hard drive requires 0.85A to work which is +0.35A above the USB2 specification. The Universal Serial Bus specification states that to adhere to the standard up to 0.5A (amps) can be drawn from a single port. USB power problemsĪ significant limitation for running a USB drive on a Raspberry Pi is the power requirements. A cheap USB powered external drive with many times more space can be had for a similar price to a top capacity SD memory card.
SD memory cards are cheap and popular with low-end specifications but reach an affordability and storage cap when their sizes increase. But one of its limitations is the storage options if you wish to use the machine as a file or multimedia server. The Raspberry Pi is a great and flexible little device.

So I have a created a quick summary of the commands on how to mount a drive below. This article was meant to be a brief piece on how to mount an external USB drive, but it quickly spiralled out when I started writing about all the nuances and potential issues one might encounter.
