Question : Invalid partition table on netware mirrored drive

Running Netware 6.5 at home to host my Groupwuse email system.  Received an error message "Alert! Uncorrectable memory error previously detected in xxxx xxxxh"  on bootup and it would hang.  Tested all memory and it appears one of the chips went bad.  After that I got "auto restart after abend error on startup of Netware, not even able to do a server -ns -na.  It appears the C volume had tons of errors, cleaned up the errors and everything started up again fine.  Here is my problem:
I have one sata drive mirrored to the other in case of disaster, both drives have a booitable dos partition with identical server directories for Netware.  I disconnected the drive 0 and attempted to start up from the second sata drive which should be the same.  I get the message invalid partition table and can't seem to figure out why.  In fdisk it shows the first drive with a C partition (marked active) along with the Netware partition and the second drive shows a D partition (marked as active) along with the Netware partition.  I had manually previously on the D drive created the dos partition and sysed it but can't understand why I can't boot from it which I would like to do since a disaster can happen.

The Netware screen shows the netware partitions have synced are 100% mirrored.
The server has been up for years, I can't kill it if I tried as much as people hate Netware, at some point I will move it to SLES or Windows Server.  Just need an answer to the queston though
