inter partition large file transfer problem

When i try to copy a file >300MB from one location say Local Disk
to Local Disk:E the computer freezes.

So as to tackle the problem i tried to analyze the disk writing
characteristic by looking at resource monitor.
i have Windows vista OS. during the transfer it transfers certain
amount of data then the orange light indicating the harddisk level in
the CPU stop to blink ie it remains glowing. then the computer doesnt
respond.

the page.sys located in the Local Disk:C shows the high characteristic
of writing during transfer before freezing.

please save me from reinstalling the vista....
