11.2-RELEASE-p9
Tested with >1 disks:
--
SATA disk connected directly with SATA cable to MBO, shows correct amount of sectors.
diskinfo -v ada1
When I connect it to the same MBO over USB to SATA adapter, 1 sector is missing (the last one)
diskinfo -v da0
Having last sector inaccessible is a huge problem as many "things" use it for a metadata.
This has many times caused MBR disks occasionally to not be visible at all while being 'da0' (gpart: No such geom: da0.)
And also GPT disks to be in a [CORRUPT] state upon reattach directly to SATA interface.
Before submitting a bug, there is only 1 variable left that I can't test, because I have only 1 USB to SATA adapter.
It might be a hardware issue, so can someone else test this too?
