Identical Data for External Drives

My system has three different external drives connected by USB. I'm seeing Speccy report IDENTICAL data for all three drives in fields such as

  • Serial Number
  • Firmware Version Number
  • Power On Count
  • Power On Time
  • ...

This is from Speccy Professional Edition v1.31.732 (64-bit). What's going on?
