    Optane memory is primarily a cache for a spinner HD usually 7200rpm hd.
    But it is a drive, and is set in RAID formation with the hd.
    In order to use it as a separate drive it has to be set in ahci mode in the bios .
    and the windows has to be set in the same as windows will continue to look for the raid.


    Switch from Raid to AHCI
    Exactly, It is just a cache drive and Windows is loaded on the 1TB Seagate Barracuda Pro.

    Its how I have my HP set up. I replaced the 16 gig with a 500 gig M2 and the hd with a 1 T Sdd.
    Now M2 C and Sdd D.

    Art,

    I don't know your computer.
    The pc in question is a Lenovo Legion Y530-15ICH

    - My m.2 drive can take a full-sized drive and it can boot from it.
    The m.2 drive is only small - 16Gb and only around 50 mm long.

    I gather it is used in this pc as a small cache drive that contains the Windows OS so that it boots up fast.

    - It seems a waste of M.2 technology for it only be to capable of hosting a cache thing.
    Agreed.

    - It is built in to Windows 7 & 10
    Thanks.

    I'm surpised that you have that much data to back up if you don't have video files.

    Audio files, perhaps? 200,000 copies of my pdf file?
    Just thousands of pictures of the grandchildren!

    Plus, it will allow my wife to go several months between backups to her external hard disk!

    That's how it seems to be implemented in this particular laptop. The main storage being a 7200 rpm 1TB Seagate Barracuda Pro.

    Seeing as the manufacturer (Lenovo) puts Windows in this m.2 drive, how can I clone the Windows installation to a larger m.2 drive?

    @Porthos

    The NVMe m.2 in my wife's laptop has a 2242 form factor (22mm wide and 42mm long?)

    Art,

    The others know more than I do.

    All I can contribute is that Crucial offers to sell decent sized M.2 drives for you computer and that's a reliable sign that it can be done
    RAM & SSD Upgrades | Lenovo Legion Y530 | Crucial UK
    I had to go to the end of the initial list and click on something like See more in order to see the suitable M.2 drives.
    You don't have to buy from Crucial. I have provided the link merely to demonstrate that solutions exist.

    I thought you said it was not on the M.2 but the HDD?

    The actual Windows is on the Hdd not the optane
    windows wouldn't fit on an 16 gig.
    Use the Intel app to turn off optane and you can backup up the Hdd fairly well.
    I used Macrium reflect.
    After I replaced the 16 gig with the 500 gig M2 I restored Windows to the new M2.
    I had to reset my bios to ahci from raid.

    After some investigative work last night, it appears that Lenovo have put the OS on the m.2 drive - I'm guessing so that it boots up faster??

    Seems that the 1Tb drive is there simply as a volume storage device.

    I say 'appears' because as one drive (seemingly NOT the 1Tb Seagate) had failed, the machine won't boot at all. Taking the 1Tb drive out and hooking up to a USB caddy, I could view files & folders and transfer documents and stuff from the drive. This makes me suspect the m.2 drive had failed.

    If so, wouldn't the machine boot with just the HDD in situ?

    I couldn't see anywhere in BIOS to alter the boot order.

    Is the m.2 used as a sort of pre-fetch cache?

    As an aside, how big is Windows 10 Home? I thought it was less than 4Gb??

    If Windows is installed on the M.2 then it needs the M.2 to boot. So your diagnosis is probably correct.

    Please confirm that it is not on the HDD by checking the folders on the HDD. Are they only the folders you have created or is there also - Program folders, [possibly] Program folders (x86), Windows, PerfLogs, Users?

    32GB drives can just about get away with Windows running but they often experience problems.
    - I understand that the neatest installations of WSindows 10 Home can be as small as 10GB
    - On my simplest computer Windows and my applications take up 20GB.
    - On my main computer the same Windows & the same applications but different hardware take up between 40-50-60GB depending on what mood they are in.
    - Your reference to 4GB is probably a misplaced reference to the size of the installation ".ISO" file which was hovering around 4GB for a long time before swelling to 5GB
