Luke,
Thinking about it more are you using NTFS ot FAT partitions?
NTFS has a habbit of splitting files all across the disk.
In either case you are likely to get very different results across machines,
or even the same machine after a Defragmented has been run or after a
reinstall of the software/file copy etc.
Are you trying to optimise the buffer size??
Beware the NTFS uses 512 byte blocks and FAT could be from 1k to 32K logical
blocks.
Myles.
