The instructions of https://www.debian.org/CD//faq/#verify for "written optical media" apply to USB sticks, too. I.e. learn <sector count> and <sector size> from: /sbin/isosize -x <device> Use them to curb the data to the original size of the ISO image and pipe the stream into the checksum program: dd if=<device> count=<sector count> bs=<sector size> | sha256sum > does live cd in usb stick change after running and using for long time? that > is, all writes are performed in memory? I expect that Debian Live itself does not alter the ISO filesystem. But some EFI implementations and a certain operating system feel entitled to create files in the EFI System Partition filesystem of the USB stick, which is actually a data file in the ISO filesystem. See https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1056998 (Best to be read bottom-up as the way to the diagnosis was curvy.) Have a nice day :) Thomas
