Why is 7 so slow while copying large files between part

Everything is so slow e.g. opening of FireFox, opening of Excel, opening of Task Manager etc...while I'm copying 750GB of data from one partition to another partition......why? I'm running Windows 7 x64 7100 on a seperate partiton and I have a Q6600, 4GB ram and 5 X 1 TB WD Black edition drives...Task Manager is showing 33 running processors, 3 - 5 % CPU usage and 1.35GB of ram usage.....is this a Windows 7 bug?

p/s Windows 7 is super fast when I'm not copying/transferring large files between partitions!

Hmmmmm, I don't have such problem while running XP Pro SP3

What could be? I even disabled AntiVir while copying/transferring......

I can not afford to format the partition which has Windows 7, cause I will have to re transfer nearly 900 GB of files, unless there is a way not to redo the 900 GB transfer, here is my setup:

Drive 1 Partition C - XP SP3 (40GB), Partition D (900GB)
Drive 2 Partition C - Windows 7 (40GB), Partition E (900GB)
Drive 3, 4, 5 - all in single partition (930GB)

Western Digital's Tool wouldn't let me just format the C partition alone, if I delete or format C in drive 2, all partitions would be lost!

I notice Windows 7 is pretty slow when moving things around hard drives myself. Compared to XP anyways. So it may just be a normal thing you're experiencing.

Im going to take a guess that you had XP running on the machine first then installed Win7 as a second OS on the same drive. When you installed 7 you didn't let it format the drive. So windows 7 is trying to use the old XP drive format. With each new version of Windows they update how it formats and writes the FAT table to the drive. Windows 7 could be slow when copying large files due to its writing to the drive in the older XP drive table format, it maybe a small bug the only way to tell is if you reinstalled Windows 7 letting the install format the drive and then test again.

When you consider none of my hard drives are over 500GB I obviously have never tried to move 900GB of data between drives or partitions. I do occasionally move 9GB and it takes four or five minutes. I've never had an OS on my computer that would move 9GB faster.

Where did you get this information? The only difference I am aware of is that MS updated NTFS to version 3.1 when XP came.
