During the creation of a new disk, the error “The media is write protected” pops up.
Check if the disk (or volume) is in a read-only state:
DISKPART> attributes disk Current Read-only State : Yes Read-only : Yes Boot Disk : No Pagefile Disk : No Hibernation File Disk : No Crashdump Disk : No Clustered Disk : No
If the disk or volume is in a read-only state, clear the attribute with the following command:
attributes disk clear readonly attributes volume clear readonly
Go ahead with the creation of the new disk
