Background

4 x SATA 1TB RAID 5 setup (2.7TB) GPT file system
After playing around with norton ghost 14 to clone an IDE drive, for some reason it affected my RAID 5 setup.
A "Boot :X" 33mb drive appeared and shortly after, two out of 4 of my raid disks stopped working.

Current situation

2 drives detected as part of the raid setup, other 2 detected but not as part of the raid. Suspect software problem.

Just need one drive to work so I can rebuild.

ANY INFO WELCOME PLEASE!

Thanks.

Have you run hard drive manufacturer diagnostics on each drive?

Click the link for Drive Fitness Test, it's the diagnostic :thumbsup:.

Follow the directions for either burning a CD or installing on a floppy (your preference).

Then...insert whichever into appropriate device..reboot system...go into BIOS and change boot order so that the system will boot from the optical drive first, not the hard drive. Hit F10 to save changes made in the BIOS, it will exit the BIOS and reboot.

The bootable hard drive diagnostic should come onscreen. You want to run the long test (if long and short are offered) on each drive and write down the end results for each drive.

I have ran the Advanced test and the quick test and both came back as "Disposition code 0x00" so I'm guessing theres no physical damage.

I just need to find a way to force the Raid controller to detect those 2 drives as part of the array and not single. Any ideas?

LOL...my experience with arrays is just limited to knowing how to set one up and how to install XP, etc. Once I learned that, I removed the array.

If your RAID controller is onboard...there's a chance that there's a utility for RAID situations. I'd search the manual, but more importantly the website of the motherboard manufacturer.

I am assuming that you don't have a "boxmaker" system (Dell, Gateway, etc.).

Haven't bought a prebuilt machine in 15 years, so I guess I will consult the raid controller manufacturer then. If anyone else has anything to add that would help.

Found some software called "test disk" it shows there are 2 partitions:

MS Reserved
MS Data

I'm guessing the reserved shouldn't be there, how can I remove this so that just the other remains without compromising data?

I checked one of my healthy disks and I wasn't able to access the file system, but on the bad disk I saw the two mentioned before.
So my bad disks are now registering as single drives instead of part of the raid array. I'm currently trying to make the structure of my bad disks
as close to my healthys as possible using testdisk.
