A few days ago we were talking about it :) First catch it returns .t. if you say :
directory('a:\')
even if there were no disc in. Of course checking device being ready is your problem and every drive has a root dir.
Next it doesn't have a way to determine when directory exists but hidden or system. ie: on a w9x system we know there is windows\sysbckup dir :

? directory('c:\windows\sysbckup') returns .F.
? adir(arrFolder,'c:\windows\sysbckup','DHS') returns 1 correctly.

IMHO only a .t. value from directory() would make sense when something other than root is queried. IOW I'd never trust and use it.
In other cases I would do a adir() and check if 5th parameter has a D in it :

lparameters tcDirToCheck
local array arrCheck[1]
local lnFound
lnFound = adir(arrCheck,tcDirToCheck,'DHS')
for ix = 1 to lnFound
 if at('D',arrCheck[ix,5])>0
   return .t.
 endif
endfor
return .f.

And as a suplementer this would check for drive being ready :

Lparameters tcDriveName
oFS = CREATEOBJECT('Scripting.FileSystemObject')
For each oDrv in oFS.Drives
  If oDrv.DriveLetter = upper(tcDriveName)
    Return oDrv.IsReady
  Endif
Endfor
Return .F.
