Hide your E2B partition from Windows

Ric asked me how to add a menu to hide\unhide the E2B partition from Windows so that it could not be accessed by unwanted programs and viruses, if he plugged it into an infected Windows system.

Here are the HidePtn.mnu file contents:

# Use this menu to hide or unhide the hd0,0 partition (first partition of the E2B drive) so that Windows cannot access it

iftitle [hiddenflag (hd0,0) > nul] UnHide E2B Partition\n Unhide the 1st partition
unhide (hd0,0)
configfile (md)0xa000+0x50 || configfile /menu.lst

iftitle [checkrange 0 hiddenflag (hd0,0) > nul] Hide E2B Partition\n Hide the 1st partition
hide (hd0,0)
configfile (md)0xa000+0x50 || configfile /menu.lst

If you need to access the contents of the E2B drive from Windows when it is the 'hidden' state you can boot it using an emulator (e.g. RMPrepUSB - QEMU or MobaLiveCD.exe or VirtualBox+VMUB or VMWare) and then run the UnHide E2B Partition menu entry. Then unplug and reconnect it and the E2B partition should be visible to Windows.

If you want to hide/unhide the 2nd partition of an E2B USB hard disk, change (hd0,0) to (hd0,1) in the menu.

This HidePtn.mnu file will be  included in the \_ISO\docs\Sample mnu Files folder of E2B v1.58 and later versions.
