3T My Book show RED line in My Computer display

3T My Book has 261 GB free space, yet the display for “My Computer” shows a RED line.  I can read the files, but wonder if this means a hardware failure or ? has the drive been infected with a virus?

TIA, Max123

Hello,

This is a Windows warning that indicates your drive is more than 90% full. Or has less than 10% free space.
