External Hard Drive Question

[Hachet]

I have two external USB harddrives. Each drive has a shortcut on the
desktop. Just today, a red circle, with a question mark inside, appeared
for the first time. I always use the "safely remove hardware" option to
disengage the drives. Even with the red circle and question marks, the
drives operated normally.

What does the red circle and question mark mean and how can I get rid of
them ? TIA

Try deleting the shortcut
and creating another

Did it and the red circle is gone. Tks
