You should see this in the SMART report. See: https://superuser.com/questions/921246/usefulness-of-badblock-on-modern-storage-media and https://superuser.com/questions/384095/how-to-force-a-remap-of-sectors-reported-in-s-m-a-r-t-c5-current-pending-sector My experience is that a few drives have a small number of bad blocks remapped but continue to work. Most just keep generating more bad blocks and soon stop working, so you want to copy of the data ASAP. SMART does not work with all USB cases. It is best to shove the drive into a desktop. If the drive is under warranty you may need to run the vendor's diagnostics.
