I am trying to convert my dynamic disk into a basic disk. I already have all of the data backed up on a second hard drive. When I go to diskpart I: select my disk, then I select the volume that I want to delete, then when I to "delete partition" diskpart simply crashes. There is also a second partition on the disk labeled SYSTEM_DRV that is 260MB. This disk is not a boot drive and I simply use it too backup files to and to record gameplay. I would really appreciate it if someone could show me how to convert this disk back into a basic disk.
