SYMPTOMS
When you run the Microsoft Exchange Server Performance Optimizer, it may fail and
display the following error message:
The following drives could not be tested due to an error (drives affected).
RESOLUTION
Performance Optimizer performs various tests on the drives during its optimization
process. The error above can be generated when too little free space is available
on the drive. Microsoft recommends a minimum of 10 MB free on each drive before
running Performance Optimizer.
The error may also be generated by actual problems with the drive. Look for drive
errors in the Windows NT Event Viewer System log from before the Performance
Optimizer was run. Errors about the drive generated while Optimizer is being run
may be caused by too little free space.
This behavior is by product design
