You should start by entering "usb hard drive" without the quotes into the Search box at the top left of the page. Read the selections found and select,for starters, How to connect a USB Hard Drive to SME 6.0.1-01. Then if you have questions post them mentioning that you read the search results. I have connected an external USB suscessfully to SME 6.0.1-01 using the suggestions found in psoren's "How To".
