When you buy the new HD it will come with cloning software. Clone your current configuration to the new drive and use it as the boot disk.
I posted a thread yesterday and appreciate the responses...but with more knowledge I seem to be more confused! HAHA
I currently have 2x500gb Seagate HDDs in a RAID 0. I backup all sensitive files with an external usb drive. I really don't like the RAID 0 because of the 2x failure risk. I have VISTA and programs "tweaked" how I like them but want to move my OS to a partition on a 3rd HDD (which I will buy) move the apps to a 2nd partition on the 3rd HDD, and then setup the 2 Seagates in a RAID 1. On the RAID array I would also store a disk image of the OS and Apps....and the RAID array will be backed up to my external HDD.
Am I making things too complicated? Will I have to just reinstall things on the new, 3rd HDD and then go from there?
Any suggestions would be greatly appreciated.
