Recently at work we were each supplied with a 512Mb Lexar JumpDrive FireFly. These are rather nifty, highly portable USB drives and come with some Google applications on the drive ready for install.
Unfortunately, with a dozen identical drives (we all got kermit green) floating around the office, it can be difficult to tell them apart. Being so small, there's not a lot of room to write/label anything on them. Also, when you plug it in to a computer, autorun kicks in and tries to get you to run the Google installer.
My solution was to modify the autorun.inf file to display a personalised label and remove the autorun prompt. My customised autorun.inf now looks like this:
Label=Lexar - Dean Heard
The end result is that autorun no longer pops up, and the drive now appears in Windows Explorer with a meaningful name:
Whenever you change the autorun file, you need to reattach the device for the changes to appear. Check out this page for more options.
