Hi,

yesterday I enlarged one share of a OES-Server to 4.87TB. After that it 
seems
the drive mapped to this share is no longer properly visible in at least 
CygWin 2.5.[12]/2.6.0-0.3.
An old installation with 1.7.35 works still fine.

For T: (failing) and L: (ok, hosted on the same server) getVolInfo shows 
the following:
