I have a 3TB drive attached via SATA, with independent PSU. Despite my best efforts I cannot get it to be recognized as anything more than 801GB/746GiB. This drive works in another machine fine. I tried a low-level wipe (dd if=/dev/zero of=/dev/sda bs=1M), as well as creating new GPT partition tables.
hdparm -I does correctly report info, but `cat /sys/class/block/sda/queue/physical_block_size` reports block size at 512. Any thoughts?

Armbian Debian 3.4 image
