Windows To Go is a new feature in Windows 8 Enterprise that allows Windows 8 Enterprise to boot and run from USB hard disk and flash drives. However this feature is not limited to Windows 8 Enterprise and can be unofficially enabled in all versions of Windows 7 and 8 by using a tool called WinNTSetup
A USB Flash Drive can be disguised as a USB Hard Disk using Filter drivers. This way a USB Flash Drive can be partitioned using the inbuilt Disk Management Tool(diskmgmt.msc) and all the partitions of the USB Flash Drive can be accessed simultaneously in Windows Explorer.
There are many ways and tools to hide or protect important data on a USB Flash Drive.However a simple format of the USB Flash Drive can erase the important data.
Using Fbinst, a hidden partition can be created to store important data.This hidden partition stays even after formatting the USB Flash Drive.
