    Hello, since some days my HP Zbook 15 G2 doesn't recognize the Optical drive. That has occurred after I attempted to read a DVD. Before that episode, all worked well. The model number of it is SU208GB.
    This is the error message I got when I open the device manager in the general tab: "

    Here is what is displayed in the Events tab of the Device manager:

    Here is what I did to try to fix:
    . in a CMD windows I run the following: DISM.exe /Online /Cleanup-image /Restorehealth;
    . then this command: sfc /scannow and it fixed existing corrupted;
    as suggested here on the Microsoft website: https://support.microsoft.com/en-us...er-tool-to-repair-missing-or-corrupted-system
    I tried to uninstall and reinstall the SATA interface from the device manager as suggested in this post of the HP community: https://h30434.www3.hp.com/t5/Noteb...recognized-HP-Pavilion-15/m-p/6490107#M435659
    . I tried to fix a possible corrupted registry as suggested in the same post;
    . I downgraded the BIOS the upgraded it again.
    My optical drive is not recognized yet; even when I boot and enter in the BIOS setup it is not detected.
    Another option would be to install windows or Linux in a secondary drive to check if it is detected.
    I wonder now how to check if it a hardware failure?
    A hardware failure of the optical drive or of the SATA connection of the motherboard with it?
    Thank you.

    You dont need to install linux to check if its detected just pop in a live usb, then check if it works. I think that's your best shot, but if it's not being detected in the bios it usually a bad sign.

    I the end I have fixed it. I've bought and installed the spare part 735600-001 now it features the following model number:: GUD1N.

    Soon after the installation, I rebooted it the first time but the optical drive was not yet recognized. I then rebooted again to access the BIOS to check if it was detected, and yes it was. When the second boot was ended the drive was successfully recognized.
