  1. Thank You!!!!!!!!!!!!! This helped me a lot!!!!!

  2. thanks........................!!!!!!!!!!!!!!!!!!!!!

  3. Thnx a lot man.. Worked like a charm. I guess I owe you :-)

  4. It is not feasible in case we have no backup harddisk to copy all volumes from the dynamic disk. The more reasonable operation to do is to directly (on the fly) convert dynamic disk to basic disk without doing a backup in advance. Can you perform such a task?

    Maybe using a Disk Manager like MiniTool Partition Wizard or Easeus Partition Master.
