See what About This Mac > More Info... > System Report tells you about the disks format. Look at:

  • Partition Map Type it should be GPT (GUID Partition Table)
  • File System would be Journaled HFS
  • Lastly look just below File System for Writable what does it tell you?

You may need to reformat the drive.
