    IMHO, it was a mistake to make USB block storage use the same line of names also used for local hard disks. Sure, the block device drivers for USB mass storage internally hook into the SCSI subsystem to provide block level access, and that’s why the drives are called sd[something], but why should I as an end user have to care about that? A USB drive is very much not the same thing for me as a SCSI harddisk. A NVMe drive on the other hand, kinda sorta is, at least from a practical purpose point of view, yet NVMe drives get a completely different naming scheme.

    That aside, suggest you use lsblk before dd.

      I still made the mistake, when I sleep deprived switched if and of somehow
      My then girlfriend wasn’t exactly happy, that all here photos and music, which we just moved off old CDs, that couldn’t be read correctly anymore, and I spent quite some time to finally move them

      Obviously the old CDs and the backup image were thrown out/deleted just a few days earlier, because I proudly had saved the bulk of it - and being poor students having loads of storage for multiple backups wasn’t in reach.
      Backing them up again to fresh CDs was on the plan, but I quickly needed a live USB stick to restore my work laptop…

      Since then I’m always anxious, when working with dd. Still years later I triple check and already think through my backup restoration plan
      Which is a good thing in itself, but my heart rate spikes can’t be healthy
