I am running Windows Server 2003 Ent 32 bit version of windows and I have 2 12 TB volumes connected with SAS interface. I can perform a Shadow copy on drive C: without any Issue. But when I try to perform a Shadow copy on the other volumes I get a Error 0x8007000e: Not enough storage is available to complete this operation. error. I installed the KB940349 patch and got the same error. Is it possible to do a Shadow Copy on a 12 TB volume using Server 2003 32 bit or do I need to change OS.
