Hard Disk, NOT Partition!
Many people get confused by drive letters. They assume that moving the paging file from drive C: to drive D: is the same as moving it to another hard disk. However, this is not true.
The operating system does not bother with physical drives. It is only interested in logical drives. By this, we mean properly-formatted partitions that can be accessed by the operating system.
To the operating system, partitions appear as physically-separate hard disks although they may reside on the same hard disk. If you partition your hard disk into three different partitions, your operating system will identify them as three logical drives (Drive C:, Drive D: and Drive E:). But they are still physically on the same hard disk!
Therefore, if you merely move the paging file to a different logical drive, you could be doing nothing more moving it to a different partition. So, please check and make sure you are moving it to a physically-separate hard disk. Preferably, it should be the first partition in that hard disk.
Parallel-ATA
Many tweakers forget one thing when they move their paging files to the second hard disk - only one PATA (Parallel-ATA) device can be active at any one time on the same IDE channel.
Most users slave the second hard disk to the first hard disk on the primary IDE channel and put the removable media drives (CD writers, DVD-ROM, etc.) on the secondary IDE channel. That is theoretically sound practice but it actually negates the purpose of moving the paging file off the primary hard disk!
Because both hard disks are on the same IDE channel, they can't be active at the same time. So, there is no way data can be read from both hard disks at the same time. In fact, because the secondary hard disk is often slower and smaller than the primary hard disk, the performance of the paging file on the second hard disk will actually be worse off.
