Permissions on PhysicalDisk0

NTFSD
1

I’m running Windows 2000. My system was originally installed with the RTM
version. I’ve ‘upgaded’ to the definitive release. Both are build 2195.

Ever since the upgrade was done, I can no longer do an
IOCTL_GET_DRIVE_LAYOUT on PhysicalDrive0. I can get geometry, but no layout.
The failure is error code 5 (access denied). winobj shows plenty of
permissions on all the seemingly relevant objects (namely,
\devices\harddisk0\DR0, which is the target of the PhysicalDrive0 link).

Anyone got any hints or clues?

I think you may need administrator privilages.
