How can I completely reset the security and ownership for a drive (ie. all subdirectories and files)?
I'm recreating a large RAID array and I'd like to "start fresh" with the absolute default security and permissions for everything.
I believe I need to run:
icacls . /reset /T /Q
EDIT: Also, what other files should I cleanup? (ie. thumbs.db, the system .ntfs folder, etc?)
Format the drive. That guarantees default security descriptors and cleans up everything else, too.
Update after comment from SofaKng:
Once you have created a fresh new volume copy everything back from your backup. Remember that permissions are not copied across volumes.
