You have just learned two very important lessons the hard way:

  1. RAID is not a backup (and RAID 0 is just a way to increase your chance of failure).
  2. If you value your data, MAKE REGULAR BACKUPS and perform frequent restore tests to be sure you can get the data back.

At this point if the failed drive isn't even recognized by your system your options are pretty much limited to sending the drives out to a data recovery company (expect this to be costly).
