This article was previously published under Q138923 SYMPTOMS
Disk Administrator displays an NTFS partition as unknown if the
permissions on the root of the partition are changed. When you attempt to
access the partition through File Manager, you receive the following error
message:
You do not have permissions to access directory.
If you try to access the drive from a command prompt, you receive the
following error message:
Access denied.
CAUSE
This occurs when a second partition or volume set is created and the
group, "Everyone" is removed from the Access Control List(ACL) and then a
specific user is granted access. The single user has normal access, but
when other users log on or if Windows NT is reinstalled, Disk
Administrator sees the drive as unknown.
RESOLUTION
To correct this problem, log in as an administrator and take ownership of
all directories or add the group Everyone back with full control
(default).
