Was that "desktop" using Windows?  Just inserting a USB key in a Windows
system changes something that changes whole drive checksums.

I once forgot to disconnect an USB backup drive when updating Windows.
The update created a Windows partition. overwriting the original table, so
recovering the data would have been a a big project with no guarantee of
success.

Only view backups read-only (sudo mount -o ro ...).  Don't leave
backup drives connected when not in use.
