I would think this is because it takes a certain amount of time to calculate the size. If you try this on small directories you should get the right answer every time. If you tell your script to wait for a second or two (or more if you are calculating a very large directory) it should work every time.

I do this:

set theDir to "Macintosh HD:Users:jeff"
tell application "Finder"
set theSize to physical size of folder theDir
end tell
log (theSize) --> "missing value"

Sometimes the tell block works (returns a value in theSize), sometimes it doesn't (returns "missing value" almost immediately). In both cases, theDir is correctly pointing to my home directory. There is no error (try block). Why would the Finder occasionally refuse to return the size?

(I'm using AppleScript Studio, OS 10.2.3. I've also seen this happen in Script Debugger.)
