most new retail harddrives come with a disk to disk copier, but if your partition is ntfs it will not work so:
get BOOTITNG from:
create a folder and extract the contents of the bootitng.zip to it
click on bootitng.exe and it will create a bootable floppy diskette for you
boot you pc with this diskette
when you see the SETUP Dialog box click on Cancel as you do not want to install it
You will receive another Dialog Box informing you that you are now entering Maintenance mode, click Ok
Click on the Partition Work icon on the right hand side of the screen
Select which Hard Drive that you want to copy FROM by clicking on HD 0
Click on the partition you want to Copy from
Click the COPY Button, you will see at the bottom Paste Pending for copy,
Select which Hard Drive that you want to copy TO by clicking on HD 1
Click on the partition(FreeSpace) you want to Copy TO
click the PASTE button
It should be pretty self -explanatory after this......
just follow the prompts......
All of the above assumes that you have your current older drive jumpered still as Primary Master,,,
Afterwards you should power down the system, Jumper the New Bigger drive as the Primary Master drive , and put
it in the older drives position on the ide cable....
Also then rejumper the older drive to whatever you need it to be....
Upon first reboot, go into the bios and do an Hardware IDE autodetect to make sure the Hardrrives are jumopered/positioned as you
need and want them to be.....
perform a chkdsk c: /r on the first disk prior to starting....
