TUAW's Daily Mac App: Disk Alarm
On today's portable Macs, especially those packing SSDs, storage space can be somewhat limited. It can be pretty easy to fill up all available space with a few large downloads, rendering your computer starved of space and creaking under the strain. Problem is, unless you watch your HDD space like a hawk, there aren't many visual cues as to when you're running low on space, and that's what Disk Alarm aims to put right. Disk Alarm does one thing; it checks the amount of free space you have on your main drive and alerts you when you get below a user-definable threshold. It's nice and simple -- you adjust one slider to set the threshold and one to set the check interval. You can get Disk Alarm to play an audible alert along with a warning when your disk gets low, but it'll also show how much free space you have in your menu bar for at-a-glance reassurance. The application used to be able to hide up into the menu bar when you closed the settings window, but as of a recent update, Apple blocked the version that had that ability. Hopefully the developer can find some way around Apple's odd blockade, but in the meantime, Cmd+W will close just the window and leave the menu bar icon. Disk Alarm is available for US$3.99 from the Mac App Store, and should save you time and heartache the next time you run out of space.
