I bought a Seagate ST3000DM001 3TB hard drive. It was sold inside an enclosure. I formatted to ext4, copied some data to it and then I removed it from the enclosure and connected it directly to the motherboard. My data wasn't visible to OS (it was seeing one unknown ~300GiB partition and the rest as free space) so I started reading about Advanced Format and >2TB drives.
I connected the disk with USB again, copied all the data, and plugged to sata once again. I used gparted to create a GPT partition table (the ubuntu disk utility wouldn't let me with
Error synchronizing after initial wipe: Timed out waiting for object (udisks-error-quark, 0), created one big 3Tb Ext4 partition, left the default

The drive is recognized correctly, and mounts properly. Files can be copied from and to the drive successfully.
Gparted shows the disk having 512k sectors which I know is not true1
cat /sys/block/sdb/queue/physical_block_size reports
Parted reports that the drive is aligned when I choose minimal:
(parted) align-check alignment type(min/opt) [optimal]/minimal? min Partition number? 1 1 aligned (parted)
Is my configuration correct? Do I have performance penalty because the disk is formatted with 512k sectors, is gParted reporting false values or I have understood the whole thing wrong?
