My Exchange 2010 SP2 stores are very big. 1.4tb, 1.3, 1.7tb and have run into this problem.

Information Store (8580) DBNAme: An attempt to write to the file "F:\Data\DBName.EDB" at offset 315530739712 (0x0000004977190000) for 32768 (0x00008000) bytes failed after 0 seconds with system error 665 (0x00000299): "The requested operation could not be completed due to a file system limitation ".  The write operation will fail with error -1022 (0xfffffc02).  If this error persists then the file may be damaged and may need to be restored from a previous backup. 

Anyone have any suggestions on how I can stop the file from corrupting? (It's already happened to the 1.4tb database).

I could move the file away from the drive and back again but to copy a 1.3tb file is estimated at least a day in each direction.  Any ideas?
