    I dont know how it has changed... I have a 256gb SSD and I had a 2TB HDD however it now looks like my HDD is a 256gb SSD! So confused.

    Hi,

    Your second HDD in RAID mode, so please wait for someone else to advice you.

    Symptoms
    User can't delete RAID array, RAID option greyed on BIOS.
     
    Diagnosis
    User can create the RAID array via "Intel Rapid Storage Technology UI" (iRST) on Windows but can't delete RAID by "iRST" and RAID is the only option on BIOS (AHCI option is missing).
     
    Before deleting the RAID array
    Always remember to do the windows recovery media before running the RAID tool to delete the array.
    With the help of the Acer Care Center (pre-installed on your system), you can create the windows recovery media on an USB stick, so you can reinstall it later.
    In the AcerCare Center, click Recovery Management -> Getting Started, and then follow the instructions.
    http://acer.custhelp.com/app/answers/detail/a_id/38147
     
    You can also perform a backup of your actual windows installation, so using the windows recovery media, you can reload your OS at the time of the backup.
    Press Windows logo key and type "backup"
    click on "Backup and restore" and then follow on screen instructions.
    http://acer.custhelp.com/app/answers/detail/a_id/37461
     
    Solution
    First of all, check the Volume name of your array on "iRST".
    Press windows logo key and type "intel"
    click on "Intel Rapid Storage Technology"
    click on "Yes" if prompted
    check on the right side, under "Storage System View", that "Volume_0000" or "OEMRAID0" is the name of the array.
     
    if Type description is:
    RAID 1 or Recovery - no data will be lost
    RAID 0  - all your data will be lost - you will need to re-install Windows
     
    Download the RAID tool
    ftp://ftp.acer-euro.com/Notebook/Predator/G9-793/RAID_Tool.zip
     
    Right click the downloaded RAID_Tool.zip file  
    click on "Extract all"
    Click on "Browse..." 
    Click on "Computer"
    Click on "C:" (normally it's labeled "Acer (C: )
    Click on "Ok"
    Click on "Extract"
     
    Now click on the Windows logo at the bottom left of your screen
    Click on the Power icon
    Press Shift key and click on "Restart"
    On the next screen click on "Troubleshooting"
    On the next screen click on "Advanced settings"
    On the next screen click on "Command Prompt"
    Select your account and type your password (if any)
     
    At Command prompt 
    type C:
    type CD Raid_tool
    type delete
     
    Once successfully deleted, press Enter and then reboot your PC.
    The RAID array will be deleted.

    Thank you so much brummyfan2 and IronFly.

     

     

    Looks like RAID 0

     

    Is there any way I can backup all my programmes and files? I seee Acer only backs up Windows.

    Hi, saw you posted on my previous post, just use the method that i used, it could be the only way to solve this

    Should I try this even if my RAID config is RAID_0?

     

    Only on RAID1 configurations:

    1. Run Command Prompt as Admin (windows logo key + x - click on Command prompt (Admin))
    2. Invoke a Safe Mode boot with the command: bcdedit /set {current} safeboot minimal
    3. Restart the PC and enter your BIOS during bootup.
    4. Change from RAID to AHCI mode then Save & Exit (F10).
    5. Windows 10 will launch in Safe Mode, once booted, be sure that C: is your SSD and not the HDD.

    ( if it gives a "no bootable device" errror, you need to check on BIOS if windows boot manager is the first bootable device.)
    6. Right click the Window icon and select to run the Command Prompt (Admin)

    7. then inside the cmd windows, type
    diskpart
    then on diskpart type
    list disk
    take note of the correct disk ID to erase
    select disk x
    (x is the ID of your HDD to erase)
    clean
    exit
    your HDD will be erased completly


    8. Then open a Command Prompt (admin) again and Cancel Safe Mode booting with the command: bcdedit /deletevalue {current} safeboot
    9. Restart your PC once more and this time it will boot up normally but with AHCI mode activated.

    if you had read my instruction you will have noticed that the RAID array need to have specific labels, your doesn't have it.

     

    so you need to edit a file to have it working on your RAID configuration.

     

    on the RAID_Tool folder, right click the delete.bat file and choose to edit.

     

    edit this string 

    rstcli64.exe --manage --delete OEMRAID0

    to

    rstcli64.exe --manage --delete SATA_Array_0000

     

    close and save the file.

     

    run the tool again

    @echo off
    rstcli64.exe --manage --delete SATA_Array_0000

    rstcli64.exe --manage --delete Volume_0000
    echo Done!
    pause
    exit

    It worked.... I had changed the RAID name from SATA_Raid_0000 to RAID! I changed it back and it deleted the RAID. I typed information and also a screen shot of the new INTEL app showing two separated drives. However I still dont have 2TB. Do I have to format it?

    FYI - 20170605_082139.jpg20170605_082203.jpgBIOS Still showing RAID

    Your BIOS has only RAID setting but it's a controller setting if you don't set 2 disks as array, so you will never be able to set AHCI.
    This is how Acer set your BIOS, just live with it.
    About 2TB, open windows disk management and delete any partition on it, so you will have a single unallocated storage and then format as NTFS.

    Not good.
    All the files and the OS are on the HDD not the SSD.
    I strongly suggest you yo backup all your data and do a windows 10 clean install
