Upgraded NT4 to 2000 AS and lost software raid

I was given an old PII450 NT4 server and decided to upgrade it to Windows 2000 Advanced Server, which runs very well on it btw. Having very little experience with raid I did not know that the raid 0 array was software raid. Of course it doesn’t appear in Server 2000. Now its JBOD that are “Damaged or Unformatted”. Is there anything I can do to reestablish the array? Would reinstalling NT4 fix it?
