My laptop has windows 10 and logs into a domain. When I plug my external drive for backups I cannot write anything, not even create a folder.Create folder

I am a user of domain and belong to administrator group on my laptop. I tried granting all permissions to everyone, authenticated users, SYSTEM...with no luck.

    Try to reset the permissions from Advanced, and set "Replace all child object permission entries with inheritable permission entries from this object". – harrymc Jun 20 '19 at 10:36

    You might try adding your account to the local machine’s Power Users or Administrators group. – harrymc Jun 20 '19 at 10:43
  • I added me to both, still doesn't work. – Oscar Foley Jun 20 '19 at 11:07
  • Must be something to do with your account. In a login as local admin, can you write to the disk? And can you re-assign permissions? – harrymc Jun 20 '19 at 11:10
