I have a desktop with 3 drives, 2 drives (500GB) set up in RAID 0. C drive contains XP OS and all programs. RAID drives contain all .wav files. I'm an audio engineer and use the computer for recording, editing, etc.
Problem: C drive (OS) crashed. I bought a new drive and reinstalled XP.
I bought (2) external hard drives (1 TB each). I cloned both RAID drives to keep data safe.
The initial RAID was set up in Windows XP using Disc Management. When I boot up with the new C drive it does not recognize the old (500GB) RAID drives. I imagine I will have to reformat them both in order to set them up in RAID 0 again.
Question: Is that a correct assumption? If so, after they are reformatted, can I just transfer the data off the (2) cloned external drives onto the newly formatted RAID drives? Will that work?
If I do not have to reformat the RAID drives, how do I get Windows to recognize them? I'd like it very much if I didn't have to reformat them and Windows would recognize them. Is there a way to do that?
That is really risky It might work but I would not depend on this. I would reccoment a clone on the whole raid 0 drive to some location or slowest but doable just copy all files to the two external drives if you do not have space to clone raid 0 drives to one drive.
@Thently: The RAID is (2) 500GB drives. I bought (2) 1TB external hard drives so theoretically I do have enough space to transfer the entire RAID to 1 external HD. I read in some forums that that is the way to do it but my software "Spotmau" does not give me that option.
@hang-the-9: how do you "turn on" the software RAID?
@alvgee: The option XP gives me to enable the disks as "dynamic drives" states that the drives will be reformatted. I'm trying to avoid that due to losing the data on the drives even though I backed up the drives (separately), I'm not sure the way I backed them up was correct. I selected RAID 0 for speed. I do need to get 2 more drives so I can set up RAID 5. My bad
@hang-the-9: I have the original data on the RAID drives still. I also have a clone of both drives. I could get software that would back the RAID drives into one external drive. It sounds like that's what I need to do. Can you recommend software that would do that? The obvious problem is that the C drive (OS) drive is shot but replaced with a new drive and OS reinstalled. I do have a backup of that drive but not a clone so I don't have the programs. I can always reinstall them because I have them and all my drivers. I am not proceeding any further without assistance because I want to make sure I don't lose the data on the RAID drive. That is the drive i need data off of.
Looks like if you used software raid, and that fails (as in your case with your drive failure), the data is gone. The thing is that you don't have a true backup of the data on the drives, two images of a software RAID0 set is just what I said before, shredded paper in two bags. There may be someone here more of an expert in RAID that can help, from what I see happened, I don't think you can get the data back. But don't go wiping out your disks just because of that, set them aside for a bit.
Just an update: I installed the new "C" drive. The Raid drives were recognized as "foreign". I learned that if you "right-click" on the RAID drive and click "reinstate the drive", it will be recognized. Sure enough, that's exactly what happened. The software RAID recognized the RAID array and all my data was intact. Just wanted to pass this along in case this helps someone in the future....
