DARWIN PERKINS  Ok, I was down to 99M on my macbook pro. I'd tried everything including disk recovery, installing/uninstalling dropbox, deleting all the dropbox files...

Nothing worked. I was going crazy.

Finally, a google search turned up this little gem. It turns out that I had about 65G of space "saved" for the dropbox cache. This computer only had about 75G free on a good day.

One click, a couple minutes of waiting, and Presto! my disk was back again.

Bless YOU! You are my friend forever.
