Windows 7: Why is 7 so slow while copying large files between part

Windows 7 Ultimate x64 SP1

I don't know if your XP install went from SP1 - SP2 - SP3. or if you had an XP disk with SP3 built in. Microsoft would've updated the format command to uptain the lager disk FAT tables. Im thinking they may have updated it again in Win 7 in ways that we dont know yet.
I am at work and can not look at the Win 7 format command over the XP one here at work. The format command show up as version 5.1.26 on a XP SP3 machine. Hopefully someone will come and post a version number of Win 7.
The other question I shouldve asked is this Win 7 x86 or x64.

One thing you could have a look at is "Remote Differential Compression" this is an attempt to cut down on bandwidth when transferring over network links.

It should not affect drive to drive transfers, but some users have reported that switching this off has improved matters with transfer of large files.

It may be controlled via the "Turn Windows Features On & Off" dialog. in Control Panel - Programs & Features.

You may want to un-check the option and see if you get any improvement - if not then you can simply go back and re-enable it

XP / Windows 7 Pro RTM

That 5.1.2600 string is the operating system version I would presume. XP is Windows NT v5.1 build 2600. Windows 7 shows as 6.1.7127.0. Again, Windows NT v6.1 build 7127.
The version comes after that and shows 0 which doesn't make a lot of sense. In XP it shows as 5.1.2600.5512 so I would presume that is version 5512.

If you open Windows 7 in a text editor you get this...

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<!-- Copyright (c) Microsoft Corporation -->
<assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0">
<description>Disk Format Utility</description>

So a lower version?

When I have some time, I'll format a spare drive with both and see if there's any speed difference while moving/copying files that I can measure.

I recommend looking into using a built-in program in Win7 which you might call super Xcopy, namely ROBOCOPY.

go to a command prompt and type robocopy /? to get more info.

"The other question I shouldve asked is this Win 7 x86 or x64"

To determine which version of Windows you have, press the Windows+Pause key combo and look under System for System Type; it'll state whether you have the 32-Bit or 64-Bit version.
