MORE INFORMATION

Dynamic disks are not supported on the following hardware:
  • Institute of Electrical and Electronics Engineers (IEEE) 1394 serial bus

  • Removable disks
  • Disks in laptop computers or laptop docking stations
A dynamic disk is a physical disk that contains dynamic volumes created by using Disk Management.
