Pomcast.biz has announces Disk Alarm 1.2.1 (http://diskalarm.com), an update to its disk monitoring utility for Mac OS X. The upgrade offers a detailed menu bar that shows you at a glance the space left on your volumes. It also adds support for Japanese and Brazilan Portuguese.

Disk Alarm will let you know in advance how much free space is available for your Mac to run smoothly. It alerts you whenever any of the volumes reaches the space left you specified. The menu bar item now allows you to display the sum of the available free space.

Disk Alarm requires Mac OS X 10.6.6 or higher and is compatible with Lion. Disk Alarm 1.2.1 normally US$3.99, but is being offered (for a limited time) at 50% of the price. Disk Alarm is available worldwide exclusively through the Mac App Store in the Utilities category.
