Raid 0 Array not working

I bought a used computer with a raid 0 array (2 ssd's).
It worked okay, but I had some problems with the disk disappearing sometimes. I "fixed" it by turning on and off.
I didn't really want to use them as 2 separate disks because I have a lot of files on it that would take forever to re-download.
So now my disk has disappeared yet again and this time it won't come back so easy. When I go to device manager I can see the "RAID 0 ARRAY" and it says device working. Not initialized.
I try to initialize it and I get "Data error: cyclic redundancy check" I tried a couple softwares like easeUS and some other stuff.
So I need some help. I really want to fix the error and use it as raid 0 so I don't have to re-download, but if I have to I will split them up.
Help would be appreciated. Fredrik
 
Solution
1. CRC generally indicates a failing drive.

2. A RAID 0 that actually fails kills off all the data on both drives. This could happen in the next 2 minutes.

3. A RAID 0 should never be used without a good backup situation

4. RAID 0 + SSD gives no performance benefit, apart from synthetic benchmarks.

5. For any used PC, your first move needs to be a full wipe and reinstall of the OS and everything else.

From your description, though...it sounds like it is too late. That RAID array has failed completely. One or both of the drives is apparently dead.
I think your ssd are probably failed or about to fail. If you get CRC errors it means that you have bad sectors on your disk. You can do a full format to take them out, but safest thing is to replace your disk/disks.

You can try diskpart from the command line to see if they can be initialized and then reformatted.

I would not trust these disks for any data.

Okay... My move will then be to split them up and use them as separate disks... One is probably dead.
This sucks because I got limited internet so I'll have to wait some time to get my stuff back. (a month atleast)
I knew this was bound to happen so I had no important stuff on it.
I couldn't afford to full wipe and reinstall because of my internet either... Thanks for replies :)
