Storage Space Virtual Disk is write protected

hi,

i have 10tb storage space 1 virtual disk , 1 volume (e:). this disk became read-only.  server manager shows virtual disk healthy readwrite access property. diskpart doesn't show disk read-only:

diskpart> list disk

  disk ###  status         size     free     dyn  gpt
  --------  -------------  -------  -------  ---  ---
  disk 0    online           60 gb      0 b
  disk 4    online           10 tb      0 b        *

diskpart> select disk 4

disk 4 selected disk.

diskpart> attribute disk
current read-only state : no
read-only  : no
boot disk  : no
pagefile disk  : no
hibernation file disk  : no
crashdump disk  : no
clustered disk  : no

but can't write disk in elevated prompt:

e:\>mkdir test
media write protected.

also, windows explorer has write-related menus (cut, move, new item) grayed-out when disk selected.

i tried rebooting , command-line/power shell command remove read-only attributes without success.

thank in advance help,

patricio.

hi john,

i think found issue. seems "deny write access fixed drives not protected bitlocker" has been enabled server it.

i can set entry (hklm\system\currentcontrolset\policies\microsoft\fve\fdvdenywriteaccess) to 0 , gain write access, go 1 when gpo gets updated ad.
