Why You Can't Convert to Dynamic Disk

The error "Can't Convert to Dynamic Disk" is a common problem faced by most users; let's look at why it happens.

  • The object does not support the operation

When changing the basic disk to a dynamic disk, certain users may see "The object does not support the operation." The dynamic disk doesn't operate on Firmware or removable disks. If a volume spanned a detachable disk, the volume breaks. Basic disks on laptops can't be turned into dynamic disks.
