Fixing Bootable USB disks in Windows 7

A couple of months back in my post on installing Cacti I mentioned that I first ran into trouble copying the image to a flash drive.   At the time I quickly moved on to another flash drive and continued to install Ubuntu. The problem flash drive got dropped back in the box with other flash drives to be fixed another day.  Well, that day came.  I needed to install a fresh copy of Windows 7, I grabbed the flash drive, started up the Window 7 USB DVD Download Tool and proceeded to copy the image to the flash drive.  Not so fast, I ran into problems copy Windows just like I did copy Linux.  Luckily, this time I wasn't under such a time crunch so I had a minute to fix the problem rather than just grabbing another drive.

A quick Google of the "Unable to copy files" error message turned up Julio Franco's post over a TechSpot. His instructions were spot on.  I just have this bit of insight to add.  He mentions at the end that you need to be careful in selecting disks.  Yes, you definitely need to be careful in selecting disks or you'll be in serious trouble when you get finished.

A quick way to make sure you get the right disk.  Unplug your flash drive, do the "list disk" command, then plug your flash drive back in, and do the "list disk" command again.  You should notice an extra disk show up between the first time you typed the command and the second time.  That disk is your flash drive.
