hiding harddrive from access

[joe]

Is there a way to hide a partition from anyone, without
using software from other vendors.. And if a drive is
already hidden, who do I undo it

 

[Roger Abell]

Do you actully want to hide it or is making what is on
it not accessible enough ?
With NTFS we set permissions that control what accounts
can get at and do what, if anything, with what is in a partition.
For example, if you have a partition at F:\ that is not where
Windows is installed, and you want this to be private to the
account named Joe and no other account, at cmd prompt issue
cacls f:\ /t /g Joe:F

For full syntax of cacls you can at cmd prompt issue
cacls /?

This can also be done in the Security dialog in the properties
of the partition root node. For Home edition this must be done
in a safe mode boot in order to have the Security dialog.
