I'm using Vista x64 Ultimate and I have been having problems with file copys. When I try to copy about 400gb of files from an eSATA drive to my RAID 5 array I get an error message about 90% of the way through. "There is not enough memory to complete this operation." I tried changing my virtual memory from system managed to 2x 2048-8000 on two seperate drives but still get the error. I have 2gb of DDR2 and a 2gb ReadyBoost flash drive. Has anyone else had this problem or know how to solve it?
