Why do I get an error message when I try to scan the SD card and how do I correct this?

[Windows Central Question]

I inserted an sd card on my pc, but keep getting an error message that says that I should scan it. Nothing happens when I try to scan, however the message warns of possible loss of data. {My pc data or sd data?} I'm doing this for someone else.

 

[RumoredNow]

Does another card exhibit the same behavior?

Sounds like a bad SD card to me. (The data loss warning is about the card.)
