Virtual Machine secondary hard drive disconnects after reboot.

Hello,

I have a virtual machine. When I reboot the secondary hard drive disconnects. When I go to disk management it is no longer there. I see it attached to the virtual machine if I go to edit settings on the VM in VMWARE. However it does not show in disk management until I go to storage pools select the virtual disk and attach it. Then it is fine until I reboot. When I reboot I have to attach it again.

Thank You,

Chris

    Hi Chris,

    Hope you're doing well.

    Are there any errors when the issue occurs?

    Please review the Windows Event Viewer on the virtual machine for any disk-related errors or warnings during the reboot. If possible, please provide me the screenshots. Thanks.

    Then, verify the settings for the secondary hard drive in the VM configuration in VMware. Ensure that the hard drive is correctly added and configured. Pay attention to the controller type (e.g., SCSI, SATA) and other relevant settings.

    Verify that there are no disk signature conflicts between the primary and secondary hard drives. If there is a conflict, it can cause Windows to treat the disks as the same, leading to connectivity issues.

    Best Regards

    Hello,

    I did find that the two disks had the same signature. However I fixed the problem but still when I reboot the secondary disk is gone. It does not show in disk management until I attach the volume again. My only other disk related errors is that the files are not available after reboot since the drive is gone. Once I attach it the errors clear. At this point I am thinking if adding another disk and copying the data to the new disk.

    Hi Cristofer, please check this one https://www.silviodibenedetto.com/windows-server-how-to-fix-virtual-disk-not-attached-on-reboot/. Hopefully your virtual disk just configured with default manual attach
