MountnuoM is just another GUI for diskutil to mount/unmount volumes.

Features:

• Unmount hard disks, AFP / SMB netshares, iDisk, disk images, flash drives, CD/DVD media (hard disks partitions will be unmounted, other devices will be ejected)
• Displays icon, node, name, kind, format, size, free disk space and S.M.A.R.T status (for supported devices).
• The actual view will be updated automatically, S.M.A.R.T status will be updated every 10 minutes.
