Rapid storage technology won't rebuild to larger WD drive

[MMorg4]

I've spent over a 40 hours on this. I need to increase the size of my raid 1 array. I bought 2 WD 1TB drives to replace my 500Gb on a dell studio 435t. I first rebuilt the system on the new drives following the Intel instructions on increasing the array size using the old Intel Matrix storage 8.5 but had windows errors-- loss of desktop search, windows update wouldn't work etc. I found out that had to do with my new drives being Advanced Format drives. I couldn't fix the windows errors on the new mirror, so I started again, and reinstalled the old drives. I then applied the necessary hot fixes to my old smaller array and downloaded the newest raid control software, Intel Rapid Storage. 9.6 all which was said to fix the windows errors the next time around. Then I tried the rebuild again.....this time...

No matter what I do, Intel RST won't rebuild from the old drive to the new one. After many attempts, it rebuilds just fine btw the two older drives, but when I swap one of those with the new larger WD drive, I just get an error: ("An unknown error occurred while an operation was in progress the operation could not be completed"). I even cloned the drive using Norton Ghost, but then the problem is that RST won't create the mirror on to the second drive, it says "An unknown error occurred during the volume creation process".

PLEASE HELP!!!

Hi Morg,

I am sorry you are having problems with your system but let me help you.

Can you please try updating the drivers? Based on the chipset of your computer you can run the Intel® Rapid Storage Technology version 11.6 and it should be fully compatible.

Try this version:

Hi Kevin, Thank you for responding! I actually got passed that and now have this issue....

There you will also see that I'm running Vista 64, which RST 11.6 doesn't support (I added a system report on my other entry). Oh and yes I made it seem like I breezed through the capacity expansion but in fact it took me nearly to the brink of insanity. The new blank drives needed to be formatted by creating raids on them before they would accept being raided to from different drives. Never heard of needing to do that, but that trick worked.
