All WinPE bootable disk

WinPE or Windows Preinstallation Environment is a small operating system that can be used to start a computer without running the primary operating system. Usually, users can create EaseUS Todo Backup WinPE bootable disk on a disc or USB drive, and perform a system recovery process by loading into WinPE environment.

Some special hard drives may not be visible under WinPE environment, such as hardware RAID, SCSI drive, etc, due to the reason that the hardware drivers installed in the primary system cannot be automatically loaded in the WinPE environment. 
This article provides a guide to make a disk visible in WinPE environment.

Check the hard drive with Diskpart
Use Windows Shell Command to run Diskpart. With this command you can see all the recognized drives in your WinPE environment.
