How do I reverse RAID 0 back into two separate drives?

I have the Swift 3 (SF315-51G). The laptop has 1 TB HDD and 128GB of SSD. I really don't like the RAID 0 storage type and want to revert it back to two separate drives. Please help.

    Reboot and tap F2 into the BIOS menu. Check if you have a SATA mode switch in either the MAIN, ADVANCE or SECURITY tabs. Report back. Jack E/NJ

    F2 doesn't lead me to bios menu. I have to do it manually through windows advanced start up. I don't know why. But anyways, there is no sata mode switch. here pics of the bios.

    I've also tried hitting f12 doesn't lead me to bios too

    >>>F2 doesn't lead me to bios menu. I have to do it manually through windows advanced start up. I don't know why.>>>

    The good news is that tapping the F2 key ***immediately*** after pressing the power button usually gets you into the BIOS menu on newer machines. Don't wait for the ACER logo to appear because by then it's too late.

    The bad news is it's gonna a bit more involved to get the drives unRAIDed. First, you're most likely going to have to set a supervisor password to free up the two drives and change RAID to AHCI mode. Second, google "Switch Windows 10 from Raid/ide to AHCI" and follow those directions if you dare.

    Is there a way where I can wipe the drives clean and start completely fresh?

    Yes, but likely not any easier. You should make a backup image whatever you decide.  You first might want open Control Panel's Disk Management to see how the two drives are partitioned. Then report back on what you see. Jack E/NJ

    Or when creating a System Image it will tell you what partitions are on the disk (for a Windows machine I would expect a 100MB Boot partition, the C: drive, and a 1-6GB recovery partition.)

    ps agree that Control Panel is the easiest way but the latest version of Windows replaced Control Panel with Settings on the Windows button so I started there.

    Oh right! Maybe Microsoft is trying to better conform with some Linux GUI's "System Settings Control Center". =) Jack E/NJ

    Here's my disk management. For some reason the 1tb hdd is gone. Also can I use the acer recovery management for the backup image?

    That is right, the 100MB EFI partition is what I called "Boot". Also why is 118 GB "unallocated" ? Easiest to make that a NTFS formatted D drive and put all data there.

    I can. But I really want the 1TB HDD back and just try to delete raid 0.

    I've been doing some research and this is what I have found. Is there a way IronFly can help me with my issue? , I noticed he was on many cases regarding raid 0.

    I will notify IronFly to see if he can help us out here. Meanwhile you may want to re-consider the previous suggestion to google "Switch Windows 10 from Raid/ide to AHCI" and follow the directions in order to retain your current Windows 10 installation. It may turn out to be the simplest way of doing what you want. Jack E/NJ

    ok, since you can't switch from RAID to AHCI on BIOS, you can't use the "switch windows 10 from RAID to AHCI"; your system will always work under RAID management.
    this doesn't mean you can't break the actual array but that the SSD/HDD will be controlled by a RAID driver instead of AHCI...performance wise, there will be no difference on single disks.

    had you install iRST on your system?
    if so, please run it and post a screenshot of the main tab, so we can check the RAID status and name.

    the 1TB HDD is missing since is part of a RAID array.

    Just my opinion but RAID 0 (striping) is dangerous at best: if either disk fails, both go down. It is used for performance and there is no redundancy. Size is limited to the smallest disk and speed to the slowest.


    I do not have a machine that can do RAID so not sure how to remove though I suspect if you take a System Image and create a recovery disk, then remove the 1TB drive, and restore the system, it will be all on the remaining drive. Then reinstall the 1TB drive and it should appear as an extra drive. Formating NTFS and loading something may keep it from being turned back into a RAID drive. At least it is worth a try and can always Restore from a SI.


    Once upon a time I worked with a number of Tandem systems running NonStop. That was an interesting system, when (not if - you have no idea how unleliable the early disks were) a disk failed you could replace it on the fly.

    that's the easiest solution to break a RAID array but i don't know if the user will feel confortable to do it.

    Agreed. That's probably how I'd do it too. Wouldn't feel comfortable at all. But that RAID setup seems like such a waste of a disk space including the unallocated.  I wonder if the unallocated was originally meant to be used as a cache but somebody got a little messed up doing it? :o  Jack E/NJ

    Probably should mention that I separate SYSTEM from DATA and do regular DATA (personal files) incremental backups plus the occasional SYSTEM IMAGE and a Recovery Drive. Again in general I just need one Recovery Drive per OS. Have moved system images around on the same machine and even on different drives many times. the MS software is very good but it must complete without error (will tell you). Just need to be very methodical and patient.

    Personally, I probably replace the 1TB drive with a 250GB SSD for speed and put the 1TB in a USB enclosure as a backup drive but then do not mind building my own machines (think this desktop was built in the last century and upgraded a number of times).
