increasing size of system drive on windows 2008

I need to increase the size of my system drive.  I am replaced the 36GB drives (RAID 1) with two 300GB drives - but - I do not know how to increase the size of the RAID  partition.

You can do backup & recovery with different software such as StorageCraft, Paragon, Acronis and Symantec.

I personally use Hard Disk Manager which is cost effective and has all the features you need.

That depends on your RAID controller.  First you need to understand what your controller presents to the BIOS.  Does the BIOS see a 36GB drive or a 300GB drive.  If you just replaced the drives, then most controllers will continue to present a 36GB device.

Check the manual for your controller and do whatever the controller requires to present a 300GB device to the BIOS.  After you do that  then you can just go to disk manager and resize the partition.   You can do that with disk administrator.

How did you go about exchanging the drives? How did you copy the data to the new RAID1?

I replaced first 36gb drive with 300 - waited for rebuild to complete then replaced second drive with 300

I did not see an option in raid controller to change size of virtual disk

You can't resize a RAID array that way.   You need to do a full backup, destroy and build a new RAID1, then restore.

What do you recommend for doing a backup the would not necessitate reloading Windows?

I'm a UNIX guy so I would just boot the system to a USB stick and use dd, then partition magic, but that isn't for you unless what I wrote makes perfect sense.

As this question indicates you don't have a disaster backup anyway, then I suggest investing in some commercial software.  The O/S you are running and RAID controller are factors on the price and what you can buy.  I suggest going to acronis.com and looking at their trueimage software, but call their support / presales line to make sure your O/S and controller is supported.
