Mountain is a utility for managing disk volumes. You can mount and unmount volumes or drives with a couple of clicks. Mountain is $1.99 in the App Store, and installs easily.
Mountain lets you manage any mountable volume, whether hard drive, CD, DVD, or removable media of another sort. With a couple of clicks you can mount, unmount, or eject a volume. You can manage individual volumes or all volumes at once. You can use Mountain to spin down an attached drive without physically disconnecting it, and then spin it up again if you want it. When an app is using a volume you're trying to work with, Mountain will let you know. The Mountain interface is clean and presents new options with pop-up menus and dialogs.
While Mountain has a simple purpose, it does that purpose well. With Mountain running we were able to better control our mounted and attached volumes, and while the things that Mountain does can be done in other ways, Mountain makes them all simpler and easier. Once you've used Mountain you will accept it as a standard tool on your Mac.
Editors' note: This is a review of the trial version of Mountain 1.0.2.
