Issue

Description of problem: On win8.1-32, during iozone test do system reset, after system reset, the data disk letter missed. Before run iozone test: The output of command "fsutil fsinfo drives" as: Drives: C:\ D:\ E:\ S:\ After system_reset: The output of command "fsutil fsinfo drives" as: Drives: C:\ D:\ S:\ The data disk letter E is missed. Also hit this issue on win10-32 vm. Did not hit this issue on win10-64, win11-64, win2022.
