Read-Only Mode 

This option protects the contents of the drive by not allowing users to alter or add files. This 
feature can be enabled in two different capacities. 

All users and administrators:

 Can be enabled by the administrator and user in the 

Screen Selection Menu. Enabling this feature here will force the device to launch in 
Read-Only Mode until the device is locked. This is helpful when using unknown 
computers. 

Users only:

 Can be enabled by the administrator in the Administrator Menu. Enabling 

this feature here will force the device to launch in Read-Only Mode for 

Users only

 until 

the feature is turned off. For more information on finding the Administrator Menu, see 
Administrator Menu Screen Options. 

Boot Mode 

After authentication, selecting Boot Mode from the Selection Screen allows you to boot an 
operating system, such as Windows To Go, from the Sentry K300. In this mode, the device can 
lose momentary connection with the computer and remain unlocked. Only select Boot Mode 
when planning to run an operating system from the Sentry K300. For a more secure connection, 
it is recommended to use 

Connect Mode

, unless Boot Mode is specifically needed. 

If Boot Mode is selected and the device is connected to an operating system like a normal flash 
drive, it will automatically be remounted after safely ejecting. To lock your device, physically 
remove it from the computer. 
To use boot mode: 

1.

Install an operating system on the drive. During installation of an operating system to 
the Sentry K300, the drive does not need to be in Boot Mode. For installation 
instructions, please refer to the portable operating system’s guide.
