How do you rebuild a Failed Raid 5 or recover data from the two remaining members ?

2003 server with a HighPoint rocketraid 2224 bios version 1.7  that was set up as a three hard drive raid 5 . One of the hard drives failed , The other two hard drives are good.
I have added exact Same drive 320 gig wd sata 2 , I also added a fourth drive , marked it as (jbod)and installed xp pro on it so i could install Highpoint Web Gui version 1.5 and attempt to repair the raid 5 . I can add  the new hd wd 320 as a spare , but it will not rebuild , it said under Raid status that array is disabled , These two drives will not run on non raid sata port(tried on several machines) (they have to be connected to the raid card to be seen)so I could use raid constructor to get their data .
Is there a utility that will mark a new drive as the one that failed and add it to the raid5 , or would that work?
I need to enable this array , or rebuild this array with no data loss ,
as their external backup had filled up and was not accepting any more backups .
I need to recover the data , as this company is down until we come up with an answer or fix.
Thanking You in advance for Your Help , Thanks

The drives are not being seen on another SATA controller? at all? even in the BIOS.
I have had to reconstrut RAID sets before but the member disk have always been seen on other controllers.

Can you please clarify.

No they were not being seen . I have reconstructed several raid myself , yes the member disks have always been seen  . I contacted Highpoint , they sent me a dos utility via email
called raidtool to re-enable the raid. I ran their tool and the raid was enabled . Now it can be seen on any sata connector. I put a new disc in slot 2 where the failed drive had been .
I clicked on  rebuild , it said it rebuilt successfully , but it will not boot , after about 20 seconds I get read errors . I took the drive to a vista ultimate machine, windows disk manager sees the drive and wants to initialize the drive , however I believe that would kill any hopes of recovering data .I am in the process of running getdataback ntfs ,
What is your suggestion ?

In the 1st instance  I would not use RAID 5 without a spare on a controller that would automatically rebuild the array. RAID 5 is not as is would seem anyways, your best bet is RAID 0+1 IMHO.

But dont worry about that now. Now you have an array that is rebuild but is giving you errors, am I right?

If so I would recover the data to another disk. In fact do you have skype so we can talk about it? send me your skype name so we can talk.

don't worry about changing the disks, so long as you don't write DATA to them, use RAID Reconstructor to reconstruct the DATA and then make an image that you can recover using getdataback ntfs. This has worked for me in the past but is not an easy or fast process but I believe it is the only option you have. once the DATA is recovered restore it to a RAID set you can trust.


Good luck
