The highlighted file names and drive name just appeared like this when I turned Win10 on yesterday. worked great for a week. Formatted exFAT on Win 10 AU. tried all usb hubs on 3 different win laptops and 1 mac. All dshow the same.
It is a my passport ultra 1 Tb just bought before Black Friday.
Any one Know what why how?

Hello,

Based on the information you have provided I believe this data has been corrupted or your drive has been infected with a virus. You can either run an antivirus to make sure your drive is not infected and/or try using a data recovery software.

I did run win defender and Malware-bytes none found and I only had copies of data from another external that is just fine.
what would cause the data to be corrupted?
I went ahead and reformatted to exfat32.
Do these drives not work as well in exFAT32?

We have found exfat to be more prone to corruption than other file systems, ntfs, hfs etc
