We'll this is what happened. I have an alienware m18x, 2hdds, primary is 750gb (7200rpm)with no partition, secondary is 1tb( 5400rpm)with 3 partitions. Off lately few days back my system started hanging a lot, I did all scans, removed lots of viruses but the system performance wasn't the same as before. So I defragmented the disks and today morning I got up a pop up from intel rst suggesting me to put the disks in raid 0. After a lot of suffering from past 10 days I was actually excited that it showed me an option to increase the disk performance and I clicked on it.

Few minutes after clicking did I realise my mistake that I don't have a backup of the data. I read that I will lose all data. I have just shut down my PC at 9% migration.

Now I want to know is there anyway that I can save my data. Can I cancel raid ? Or say should I plug out my hard disk and connect it to a different computer and then will I be able to copy my data ? Any help is highly awaited. Thanks

OOOPPS!

If it has already started to stripe the drive, you are probably SOL. Normally any type of RAID the suggestion is that it should be performed with disks the same size, same company, same model. Have you tried to restart your computer? This will be the determining factor. If it doesn't boot, you are probably up the proverbial creek. If it does boot, check in My Computer and make sure you can still see all your drives are there.

It seems to me if it was 9% finished your lost.

Sorry.

I restarted and the Laptop works fine but it doesn't show hard drives. The only hard drive it shows is the primary one. The second one isn't visible

You said that you had three partitions on the secondary drive, did you have data on them?

Check in Disk Management if it shows both drives and if so check the status of the secondary drive.

I cannot see the secondary drive anywhere. Just on boot up it shows, in the bios it shows but in the computer or say disk management or the defragmenter it doesn't show.

So you don't see a Disk 0 and Disk 1 under Disk Management (Administrative Tools > Computer Management > Disk Management)? I might be wrong, but I would think that even RAID'd DM would still show the physical disks.

If it doesn't, can you start IRST and see what it says about your disks?

Also do all the files from your primary disk appear to be there?

In rst the two hard drives are shown but not in disk management. It goes on processing with the raid process.

Well it looks as if it's still striping your drives. I am not sure if it will combine your files from each drive, but my gut tells me your data on the secondary drive is gone. My guess is it's striping the data from your primary drive to over to your secondary drive. The minor downside to this (minor compared to the data loss on your secondary drive) is that you will lose 250GB of storage on the 1TB drive. This is because to stripe two drives, they need to be the same size, so IRST is going to swallow the last 250GB of your 1TB drive. You should end up with one volume around ~1.5TB when it's finished.

I hate being the bearer of bad news. I hope I'm wrong, but my gut says I'm right.
