sudo tail -c 1024 /dev/sda2 | hd  the entire /dev/sda2 device rather than
seeking to the end. This takes a very long time with large disks. Deltik
gives a nice explanation here -
https://superuser.com/questions/1267402/how-do-i-tail-a-block-device-in-linux
- of how ioctl can be used to obtain the size of a block device instead of
fstat.
