My problem is that I had a accadental power outage 3 of my 7 drives went out.  Now these drives are Segate SATA II drives less than one year old.  I had them running via software Raid in Mac OSX stripped.  How can I re-attach these 3 drives to the Raid 5 via the software?

I have High-tech 1820 Raid Card: http://www.highpoint-tech.com/USA/rr1820amac.htm#top

I don't understand, everything I read and see on TV says MAC's don't fail.
???  How could this happen?

I dont have much expeirence at all with macs but if it their software raid works like other software raids, you cant fix the raid is dead and the data is only recoverable by specialized data recovery software or a professional data recovery service, but i noticed you said you have a raid controller, are you running the raid off the controller or from a software raid in the os? if it is software and not hardware you may want to point a pointer ? to the mac os section of EE. If the raid is running from the controller(hardware raid) go into to the controllers bios and see if you have the options to force drives online if you do, force 2 of the 3 drives online (DO NOT FORCE ALL 3 ONLINE AT THE SAME TIME), see if the system boots and if so rebuild the 3rd drive, If you dont have these options in controller contact highpoint and see what they offer for recover options. If there controller dont offer any which has been my expeirnce with the cheaper highpoint cards then you back to expensive data recovery options which is why backing up data is so important.

Now Since the software can't fix it and the hard drives are formatted via NTFS is it possible to move the hard drives from that computer and put it in a Windows based environment and try to run the dos recovery utilities?  I ask because I have a client wedding photo's on these 3 drives that I was never able to retrieve before the raid broke.
