How to repair Raid 0 Via Terminal
First - take a backup of your file system. Even though it is already corrupted, it is possible to further corrupt it by trying to fix it. Make sure you have a copy before this.

Then I would suggest simply trying multiple times to check and fix the file system in single-user mode. It sounds counterintuitive, but really you sometimes need to do this multiple times to clear all errors.

You would run a check like this:

fsck -fy


Note that even though you're "repairing" the file system, it is really just fixing data structures to be internally consistent. You might (and probably will) loose data and files in the process.

As you have a RAID-0 drive, there's no redundancy in the RAID that can help you rebuild the drives while keeping all your data intact. If the data on the drive is important enough for you that you won't be happy if you loose it, then you shouldn't run RAID-0 - but rather a RAID-level with redundancy. And always create backups!
