Suppressing Low Disk Space Warning

[NTGod]

I am trying to create a script for use with Windows PE bootable USB key that will test the performance of the local hard drive. Since not every system has the same hard drive letters assigned to the local disks, I tired to have the script test them one by one accepting it if one fails. Here is the disk section of the script:
SETDISK "C:"
RUN DI_ALL
SETDISK "D:"
RUN DI_ALL

Now when I have a drive that has less than 0.52GB it pops up a warning message which stops the script till it is accepted I have tried the SUPPRESSWARNING ON before the commands but I still get the pop up. Is there anyway to stop these pop ups from happening?

We don't really support PerformanceTest in WinPE. It can probably be made to work, but we never tried it.

The disk test requires a certain amount of disk space to run. It makes sense that there is an error message when there is inadequate disk space.

Maybe you can use a DOS script to get the list of available drives before calling PT.
