You may have noticed that Vista has a tendency to take time calculating the size of the file when copying. This is caused by a new 'feature' called Auto Tuning which by default is set on by Microsoft.
To disable this feature, do the following...
1. Open up a Command Prompt with Administrator privileges
2. Type in ... netsh int tcp set global autotuninglevel=disabled
3. The prompt should read... OK
4. You may have to restart the PC for the effects to take hold.
If this does not solve your problem, the autotuning feature can be re-instated by typing...
netsh int tcp set global autotuninglevel=normal.
