One of my RAID drives failed, now what?

post #1 of 10
Thread Starter 
Ok so it seems that one of my 2 SSD drives failed on the new system I just built where everything was new. Hopefully i didnt lose much data, just the fact that i lost all installed programm plus settings and now i have got to set up everything again. So i need to ask a couple of questions.

-Do i need to format the Disk that is still functional? It shows as a disk with 2 partitions. The 100mb partition reserved for Win 7 and the other partition with the rest of the space. Do i need to reforma it, so when i replace the other drive i will setup again the RAID?

-The first time, i went into the RAID configuration utility, and i defined the RAID 0 Array and set stripe size. Do I need to do that again, since the replaced SSD is going to be same make and model and size, or will it recognize it immediately?

I just need to aks ask these questions so i will be prepared for when the replaced SSD arrives.

First off, I'm assuming you're using onboard mobo raid.

When you re-create the raid it will format it for you automatically. In short, it doesn't matter/won't make a difference.

You will probably need to as your controller can identify the drives by serial numbers and other unique information.

Yes exactly. I havent installed any additional RAID controllers. I'm talking about the onboard.

So does that mean a RAID setup only works on the computer it was created for? So if you take these 2 RAID drives and place them on another computer they wont work?

RAID information is stored on the drives, not on the controller. So if you wipe the drives, you will have to remake the RAID array again later.

Even though the information is stored on the drives, if you take the RAID array to another machine (another RAID controller), no it will not work. You MIGHT get lucky if the boards are nearly identical, but its still not a good idea.

I see. So i found the ocz toolbox util that performs secure erase. What i plan to do is.

http://www.ocztechnologyforum.com/fo...o-Vertex-LE%29


-Place the ssd as an external on a wroking windows environment.
-Delete Partitions.
-Format Drive
-Secure Erase from Software.

Are the above steps correct so i can get my exisiting working SSD into an initial state ready for when the 2nd replaced SSD arrives?

You don't have to do anything. The raid controller will automatically wipe your drive when make the raid. Granted it doesn't erase the actual files, it just destroys the file table.

Nonetheless i wont to do a clean secure erase before i recreate the raid array. Weird thing is windows still see the single disk as the total size of both disk in the RAID. I had installed 2x 60GB Vertex 2 models, and now that i used the working SSD as an external drive on windows it still sees it as 120GB! What can i do? I tried erasing the partitions and i still get 120GB of unallocated space. When i try formatting , i get an error with the operation. I tried setting partition size of 60GB and i get the partition plus the additional 60GB counted as unallocated space size.

And for some reason having the disk as external, i cant get to use the ocz toolbox which performs the secure erase. It doesnt see the drive. And i dont have the option to place the disk as an internel drive on the system i'm currently on...

Any ideas?

question..

how long did you have these ssd's before the failure. and do you think you could've done to prevent the failed one. or did you just get unlucky.


im just a raid noob passing by asking questions..

The new one just came in, but its with newer 25nm architecture (64Gbit) and is 5GB less than the original. Can i practice RAID 0 with drives of different capacity? They are both same model (Vertex 2), but the new replacment has this damn new arcitecture, that messes things up it seems. How is it that newer is not better i wonder. Especially when it comes from a valued and respected company such as OCZ...
