Description

Error Message

The USB device is plugged in and appears in Windows, but is not recognized in the recovery environment. 

Cause

Microsoft WINPE (the core of the Recovery Disk) failed to assign a drive letter to the USB drive. If the drive is formatted with newer 4k sector technology, please upgrade to System Recovery 2013 R2 or later. Check with the manufacturer to determine if this pertains to the USB drive. See https://www.veritas.com/support/en_US/article.000009793. Advanced 512e drives are supported. 

Resolution

Use DISKPART to assign a drive letter to the device. (note: changes made to drive letters in the recovery environment will NOT be made in Windows once the system is rebooted). 
 
Resolution:
 
1. From within the recovery environment, click Analyze.

2. Click Open Command Shell Window.

3. At the command prompt, perform the following:   
a. Type diskpart , and then press Enter.
 
b. Type list disk, and then press Enter. Identify the USB drive in the resulting list. The drive size may be appear smaller (example: a 1tb drive may appear as 935gb). If you do not see the device listed, it is possible that WinPE is not detecting the drive, and thus neither can the recovery environment. 
 
c. Type select disk disknumber  where disknumber is the disk number of the USB drive, and press Enter.  

d. Type list vol , and then press Enter. Identify the volume on the USB drive in the resulting list.    
 
e. Type sel vol drivenumber , where drivenumber is the number assigned to the USB drive, and then press Enter. (Note: if there are more than 1 volume is listed, you can repeat these steps and assign driver letters to each volume)
 
       Example:
 
       sel vol 3
 
f. Type assign letter=s , and then press Enter. That volume is now assigned the drive letter s. (Any unused drive letter can be used. If the drive letter is already in use, an error will occur).

g. Type exit to exit diskpart, then exit again to exit the command prompt. 
 
Select the RECOVER MY COMPUTER option. The drive should now be visible in the restore wizard. Proceed with the restore process. All drive letter changes made from the recovery environment will not remain. Upon reboot, these changes disappear and drive letter assignments are returned back to Windows.
