Happened while using RichCopy to copy over data to the drives:

PAGE_FAULT_IN_NONPAGED_AREA (50)

Invalid system memory was referenced.  This cannot be protected by try-except,

it must be protected by a Probe.  Typically the address is just plain bad or it

is pointing at freed memory.

Arguments:

Arg1: fffffa800a7ffffe, memory referenced.

Arg2: 0000000000000000, value 0 = read operation, 1 = write operation.

Arg3: fffff88004b167d5, If non-zero, the instruction address which referenced the bad memory

address.

Arg4: 0000000000000000, (reserved)
