Disk became RAW after chkdsk operation

Question

After chkdsk detected a wrong index entry and acted, a disk became RAW.

1. With diskpart, trying to clean it before formatting yields:

   DISKPART> clean
   DiskPart has encountered an error: The device is not ready.
   See the System Event Log for more information.
   

2. Could not find any corresponding entry in Event Log > System

3. Then tried:

   DISKPART> detail disk
   ST8000DM 004-2CX188 USB Device
   Disk ID: {500ACEB6-CDF0-47C2-882D-1905B6CD8F1C}
   Type   : USB
   Status : Online
   Path   : 0
   Target : 0
   LUN ID : 0
   Location Path : UNAVAILABLE
   Current Read-only State : No
   Read-only  : No
   Boot Disk  : No
   Pagefile Disk  : No
   Hibernation File Disk  : No
   Crashdump Disk  : No
   Clustered Disk  : No
   Volume ###  Ltr  Label        Fs     Type        Size     Status     Info
   
   Volume 10                     RAW    Partition   7452 GB  Healthy
   

4. Given the result, it seems that the disk is alive.

Is there anything that could be done?
