Now i added two additional 300 gig hd's, and after I edable the sata1 and sata3 in my bios The bootup recognizez all drives but the two added show as "non-raid" I know this might sound noobish but I have no idea how to bypass this or fix so please please help! btw its a Dell hahaha Xps . fuck ...

Dell, so i guess you have an Intel chipset, but wich one, the ICH6R or the ICH7R, or maybe some OEM version of them. Chances are your chipset may only support 2 drives for raid setup. But if it does support all 4 drives you have to use the Intel Matrix Storage Manager to manage your raid array volumes. http://www.intel.com/support/chipsets/imsm/ ...if you are using one of the above chipsets and not some other raid controller

most boards usually gives you a prompt to press a key to enter raid setup after/during post were you can create a raid array

all fixed ...only thing after i was done total volume of the two new drives was 400 gigs, which is kinda low since the total volume should be 550 gigs ... i mean its ok, but 150 gig loss is pretty big . fuck ...

did you migrate to raid level 5, because capacity with level 5 is n-1.

i dont think i did, this is exactly what i did. i created a array 1 from my original volume ... and then added both new hd's to the new array and made them raid, then ran disk management to format to ntfs etc and that was it ... i was too affraid of loosing any data from my original drives to do anything else any fast way of switching to raid 5 that you would recommend? btw i want to thank you again for the links yesterday that really helped a whole lot! fuck ...

Do you have two arrays now or just one? I don't think it's possbile to migrate if you have two arrays on these four disks. Besides, write performance with raid level 5 would be significantly lower than with level 0, but data safety would be much higher. Check out the white paper below for supported migration strategies (p. 17). of course you could combine a raid 0 for perfomane and a raid 5 for security on the 4 drives. http://download.intel.com/design/chipsets/applnots/31085501.pdf
