I have a 3TB drive that used to read on my Win 7 machine as 3TB, but read as 2.2TB and 802GB on my Debian server.
During an attempt to upgrade the bios on the Debian server so it could ever see a 3TB drive (This was, in the end successful) I used parted to replace the very microsofty partitioning table with a gpt partition table on the drive, but during the exercise, it reset the sector size to 512B and the drive reads now as having 746GB on either machine. I suspect that if the sectors were set back to 4K, the drive would read out with the proper size.
I have found no place where I can access the drive information on my Win 7 laptop bios where I can manually specify the sector size. I have tried to use DISKPART with an elevated permission-set, and there is no place I can see there to do a manual change of the sector size. It is a T420 Lenovo.
The Debian machine is an HP Proliant DL165 G7 and I have not yet accessed its bios to see if it has the capablity. It is more difficult to physically get at the machine to reboot it into a bios edit session, so I would rather use the Win 7 machine if it is possible.
