You will have to do a reinstall to get it to work.
Just back up your backup partition (or full hard hard drive) using any program you prefer to external media (external HD etc) then enable raid through bios and install.
I have been able to recreate my install without a "full" install but it was a bit buggy and did not really save much time.
I created a partition image (full image of the hard drive including installed os and backup partition to an external HD) using acronis then booted off of the restore CD and was able to get win7 to put the image back onto the raid partition.
Only problem was there was a boot error since the raid drivers were not installed on the backup image I put back on so I had to do a "fix" boot off of my Win7 media to fix that.
In the end, a fresh install works best but it is good to have the backup image in case you want to go back to 1 drive in the future.
Hope this wasn't too long and/or complicated (confusing)
As soon as a decent size SSD is available at an affordable price, I will that route.
Until then, running two 500gb in Raid0 and doing proper backups is what I do for security and speed
(although I have been tempted to just run them as separate drives and compare the speeds.. just don't want to do a reinstall quite yet)
They typically deliver a week earlier than what they give as Estimated Delivery Date. At least that has been my experience in the past with other laptops I have ordered from Dell. The date they gave me was 2-3-10, hope I do not have to wait that long.
I ordered the R1. With that being said, is there a noticeable difference between the core 2 duo vs i5 or i7? When I ordered I did not realize the price difference was not really that much. The difference worth me re-ordering and getting the core-i5?
