It's always moot what manufacturers actually put in the Serial Number
field on cheap devices like sticks and SD cards. The only instance
where I have several sticks from one source (a Petroleum company at
AAPG) has the ID_SERIAL¹ set to SMI_USB_DISK-0:0 which has no chance
of being unique.
For Kingston's, I was just guessing², based on a sample of two:

"part" does not mean piece/fragment, but is short for partition.
So if you have a single partition (typical for a stick when purchased),
there will only be a part1. Nothing's missing.
¹ from the contents of /run/udev/data/b8:<1+2^N> but also found in
With hard drives, the Serial Number printed on the carton is as likely
to turn up in ID_SCSI_COMPAT as ID_SERIAL/ID_SERIAL_SHORT.
² Never having depended on these fields, I hadn't given them any
thought. If this is what automounters insist on doing, I shall
keep on mounting them myself by LABEL (ext/FAT) or UUID (FAT).
Thanks for the cautionary tale.
