What's with the cross?

Hi.

Does anyone know why is there a red cross on the icon here?

This device is a Corsair USB flash drive. I initially thought it may be because the data was corrupted as there were a couple of years where it remained unconnected and I know SSD does not like that. But I formatted the drive (ExFAT) and it still shows up with a red cross in Nemo file manager.

Any idea what this actually means?

Thanks for any insight.
