GParted stuck on "Scanning all devices"

Ubuntu’s partition editor, GParted, usually scans all the hard drives when it starts. However, in some cases, it will get stuck on this “Scanning all devices” step indefinitely. By knowing what hard drive you want to edit, you can launch GParted specifically for that hard drive. Either go into run or a terminal, and run “gparted /dev/sda”, where “sda”, “sdb”, “sdc”, etc., is the identifier of your hard drive, and GParted will launch and immediately open that particular disk.
