Semulov is a small application for Mac that installs an icon on the menu bar. From this icon, you can see all the volumes on your computer sorted by category.
Categories include disk imaging, hard drives, network devices, DVDs, FTPs, iPods, and iDisks. Dismounting sounds from one of these is as simple as clicking the left button on its name.
The number at the end of the program icon in the menu bar indicates the number of active volumes. Semulov uses Growl notifications to show when a volume has been mounted or dismounted.
