After converting a hard disk from Basic to Dynamic, the volumes on that hard disk are not identified by their drive letter in System Monitor.
The volumes that are displayed in System Monitor appear similar to the following example:
Error: RErr4110(L68):Failed on DISK/LDisk MO
Error: RErr4110(L71): LDISK Object Error


To resolve the issue, refer to the following Microsoft TechNet article:

Logical Disk Names Are Displayed in System Monitor Instead of Drive Letters (Q274311)

Warning: Apply this update only to systems experiencing this specific problem


This problem can occur if the Perfdisk.dll file does not correctly parse the drive letter.  Microsoft has released an updated fix.
