When you eject, you receive:
An error was encountered trying to unmount Removable Disk <Drive:>.
Check to make sure there are no open files or windows from that volume.
When you try to format or label the media:
You do not have sufficient rights to perform this operation.
By default, local Administrator rights are required to perform these tasks.
You can change the local system policy and/or domain policy to allow other users to have the right to manage removeable media.
To grant the right locally, Control Panel / Administrative Tools / Local Security Policy / Local Policies / Security Options.
If you can't find it:
1. Start / Run / MMC.EXE OK.
2. Console / Add/Remove Snap-in.
3. Add / Group Policy / Add / Local Computer / Finish / Close / OK.
4. Local Computer Policy / Computer Configuration / Windows Settings / Security Settings / Local Policies / Security Options.
Right-click Allowed to eject removable......... and press Security. Select:
Administrators - Only administrators can eject removable media.
Administrators and Power Users - Administrators and Power users can eject removable media.
Administrators and Interactive Users - Administrators and Interactive (Standard users) can eject removable media.After
exiting the snap-in, open a command prompt and type:
secedit /refreshpolicy machine_policy /enforce
NOTE: Even though the policy lists ejecting NTFS, it actually applies to all the subject actions, on NTFS
and FAT removeable media.
