Windows 10: Can't format dynamic drive Solved

    Can't format dynamic drive

    Trying to add a second HDD to my friend's PC to give more storage.

    The HDD in question was previously the OS drive in an old PC and still has some windows and program files on it.,

    Want to format but I can't format or delete the volume. And because it's a dynamic drive, most 3rd party software I found won't touch it.

    Disk management screenie below. Disk0 is the problem. Disk1 is the current OS

    (Install language is German. Hopefully not a problem in finding a solution :P )

    Hello Bob, :)

    You might see if you may be able to use the "Clean" command on the disk to wipe it and make it unallocated. Afterwards, you could create a new simple volume on it.

    Does it give you any error messages?

    As a test, you might see if connecting the disk to a different SATA port so it's no longer "Disk 0" may help. Usually it's best to keep the OS drive as "Disk 0" instead.

    If you haven't already, you might also see if using the "clean" command in a command prompt at boot may work better.

    You have to convert the disk back to a basic disk first using disk management.

    Convert a Dynamic Disk to a Basic Disk - Windows 7 Help Forums

    1. Back up all volumes on the disk you want to convert from dynamic to basic.
    2. In Disk Management, right-click each volume on the dynamic disk you want to convert to a basic disk, and then click Delete Volume for each volume on the disk.
    3. When all volumes on the disk have been deleted, right-click the disk, and then click Convert to Basic Disk.

    The same can be achieved using Diskpart but this should do it too.

    Thanks for the replies. Have solved via an alternate route.

    2nd upgrade job was to replace a faulty dvd drive. Once that was fine I was able to use a bootable Mint dvd and user gparted to remove that partition.
