Reveal All Your Drives

If you use built-in memory card readers in a 3.5 drive bay or on your Dell Monitor, empty memory card slots will not show up as drives in My Computer. But that doesn't mean they're not still there. To reveal hidden memory card slots, open Windows Explorer then click on 'Tools' and select 'Folder Options'. Uncheck the 'Hide empty drives in the computer folder' checkbox then click 'Apply'.
