Your start up disk is your internal hard drive. Begin by restarting your Mac, as that can free up some space immediately.

Freeing up drive space in Mac OS X

If you're wondering what "Other" category in the Lion/ML storage tab is about, this may help explain:
For space issues not explained by the above, there are a few things you can try, some of which may or may not apply:
  • Begin by restarting your computer as a first step. This sometimes resolves issues.

  • For Time Machine users on notebooks running Lion or later, space may be consumed by Time Machine local snapshots, which can be disabled.

  • Check to see if some of the space is being used by your sleepimage file.

  • Check the System Memory tab in Activity Monitor to check page outs and swap used. If swap used is significant, restart your computer and track that value under your normal workload. If you have significant page outs under normal use, you could benefit from more RAM.

  • Search with Finder to see if the space is being consumed by a very large file or several large files. Adjust the 50GB in the illustration to whatever size you deem appropriate.

  • Use OmniDiskSweeper, JDisk Report, Disk Inventory X, DaisyDisk or GrandPerspective to see how space is being used on your drive. Some of these apps may show more detail than others, so try several.

  • Check your drive with Disk Utility: Using Disk Utility to verify or repair disks

  • Try re-indexing your drive: Spotlight: How to re-index folders or volumes
