MacPaw tool will quickly, easily clean, monitor, unmount your drives
MacPaw's CleanMyDrive (http://www.macpaw.com/ cleanmydrive) -- available free for a limited time at the Mac App Store -- is a new, tiny Mac utility that lets you clean up mounted drives, monitor their space usage and unmount them all in one click.
It's a practical personal assistant that helps you manage all your connected drives. It automatically cleans up system junk (DS_Store, Spotlight, hidden trashes, etc.) from external drives, freeing up disk space. It can eliminate service files, unneeded languages, outdated cache files, unwanted universal binaries, unneeded logs, files remaining from deleted apps, broken preferences, corrupted start-up items, and more.
The utility also shows the available space on the drives at a glance. The app works with network drives and knows how to deal with Time Machine volumes.
The "Eject all" feature allows you to eject all connected drives including DMG files with a single click. It doesn't sound like that big a deal, but is a convenient time saver, especially if you're working on a laptop and need to shut down and move out in a hurry.
The MacPaw solution is a no-brainer to use. Just click on its icon from the menu bar. From its preferences you can choose to have it launch when your Mac fires up -- or you can launch it manually. You can also set the utility to ignore volumes larger than 8GB.
There are drive space management apps that do more. But you want a reasonably priced (and free is as reasonable as it gets) tool for cleaning and unmounting drives, this little baby does its job with no muss and no fuss.
CleanMyDrive requires an Intel-based Mac running OS X 10.7 or greater and 3MB of hard disk space.
