I have a Seagate disk that I am trying to get partition aligned. I've tried this command in parted:

sudo parted /dev/sda mklabel gpt



sudo parted -a opt /dev/sda mkpart primary ext4 0% 100%

Get this fdisk error:

Device     Start         End     Sectors  Size Type

/dev/sda1  65535 15628000379 15627934845  7.3T Linux filesystem



Partition 1 does not start on physical sector boundary.

How do I get this disk partion aligment in parted ?

(I've also tried this guide: https://rainbow.chard.org/2013/01/30/how-to-align-partitions-for-best-performance-using-parted/

unsuccessfully)

A little info about harddrive:

Don't use parted, as it is obviously not up to the job. To partition a GPT disk, use gdisk. Alternatively, if your version of fdisk understands GPT partitions, you can use that as well. Just delete the partition and create a new partition. Format the partition with mkfs.ext4. Note that doing so will destroy any data you already have written to the disk.
