Not backing up drive

[Sam Schrage]

I have an NT client that is not backup up the D drive.   We can manually do
the incremental but it will not do it when we start the scheduler.  When
the client looks in the dsmsched.log it shows it backing up the C drive and
then skipping to the F drive.  We have tried an INCLUDE...no luck.  Any
ideas were to look?  This was a new drive specification within the last few
weeks, but he has done others before and not encountered this problem.

Thanks
