Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

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.

Version-Release number of selected component (if applicable):
kernel-5.14.0-70.13.1.el9_0.x86_64
qemu-kvm-6.2.0-11.el9_0.2.x86_64

2. Format the disk and assign a disk letter:
echo list disk > disk_Zw5C && echo exit >> disk_Zw5C && diskpart /s disk_Zw5C && del /f disk_Zw5C
echo list disk > disk_4C2E && echo select disk 1 >> disk_4C2E &&  echo detail disk >> disk_4C2E &&  echo exit >> disk_4C2E && diskpart /s disk_4C2E && del /f disk_4C2E
echo list disk > disk_JOBT && echo exit >> disk_JOBT && diskpart /s disk_JOBT && del /f disk_JOBT
echo list disk > disk_sXWe && echo select disk 1 >> disk_sXWe &&  echo create partition primary size=40955 >> disk_sXWe &&  echo list partition >> disk_sXWe &&  echo exit >> disk_sXWe && diskpart /s disk_sXWe && del /f disk_sXWe
echo list disk > disk_GwZf && echo select disk 1 >> disk_GwZf &&  echo list partition  >> disk_GwZf &&  echo exit >> disk_GwZf && diskpart /s disk_GwZf && del /f disk_GwZf
echo list disk > disk_6pxj && echo select disk 1 >> disk_6pxj &&  echo select partition 1  >> disk_6pxj &&  echo assign  >> disk_6pxj &&  echo exit >> disk_6pxj && diskpart /s disk_6pxj && del /f disk_6pxj
echo list disk > disk_CrNB && echo select disk 1 >> disk_CrNB &&  echo detail disk  >> disk_CrNB &&  echo exit >> disk_CrNB && diskpart /s disk_CrNB && del /f disk_CrNB
echo select volume E > disk_HEaL && echo format fs=ntfs quick >> disk_HEaL && echo exit >> disk_HEaL && diskpart /s disk_HEaL && del /f disk_HEaL

3. fsutil fsinfo drives
Drives: C:\ D:\ E:\ S:\

4. D:\Iozone\iozone.exe -azR -r 64k -n 1G -g 4G -M -i 0 -i 1 -I -f E:\testfile

5. During iozone run, do system_reset:
Sending command(qmp): system_reset
22:28:00 DEBUG| (monitor avocado-vt-vm1.qmpmonitor1) Sending command 'system_reset' 
22:28:00 DEBUG| Send command: {'execute': 'system_reset', 'id': 'FRpnVPqo'}

6. After the vm booted up, do "fsutil fsinfo drives" check.
Drives: C:\ D:\ S:\ 
No E: exists.
