Data on dynamic drive become inaccesible after windows 2000 server crashed

I can not gain access to the data on a dynamic drive after OS crashed.  Have a Windows 2000 server, one (1) ide hard drive with two (2) partitions.  One for Windows 2000 Server, the other is for data.  The drive was basic, but was changed to dynamic so that a second drive could be added and then mirrored. (both partitions).  The os partition was updated with all patches and updates.  Data was moved from an old server on to the data drive.  Of course no backup was run before problem or changes made.  Both partitions were set to NTFS.  The OS had some driver issues that were being corrected.  The system needed a re-start.  After the restart, a blue sceen with inaccesible boot device was found.  Decided that I could try a repair of that OS and that partition.  Did not work.  Did a clean reinstall of the OS on a newe drive with the same exact drive partition sizes.  Did nothing to the data partition.  Installed OS fine and now trying to get to the data partition.  No deal on the data.  What can be done to get to the data.  In "computer management, disk management " it says that the disk is offline, but shows both partitions and is red "X"'d and says "missing".  What's a good fix?
