Partitioning that works with sector boundaries


I have 3 hard drives of 2 TB each. One of the hard drives uses physical sectors of 4096 bytes, while the other two hard drives use physical sectors of 512 bytes.

I was told, perhaps erroneously, that my hard drive with the 4096 byte physical sectors should have their partitions starting and ending on physical sector boundaries, else access in such a partition is significantly slower than it could be.

Unfortunately this is not the case with that one drive with the 4096 byte physical sectors. So I searched for a good partitioning tool, with a Live Boot DVD, which would allow me to move my partitions to physical sector boundaries as described above. Neither gparted, KDE partition manager, parted itself, Minitools partition manager, EaseUs partitioner manager, or Acronis Disk Director has such a feature.

Does anyone know of a completely reliable, bootable partitioning tool that will allow me to move partitions precisely on a particular sector ( logical or physical ) boundary ?

I don't know about moving the partitions (actually GParted should be able to do that), but why don't you just delete the partitions and recreate them with the correct alignment?

GParted does not allow the user to specify the boundaries based on a beginning and end sector.

How do I recreate the partitions with the correct alignment if the partitioning software does not allow me to specify the starting and ending boundaries based on a sector ?

GParted uses MB alignments, which usually will align the partitions automatically.
fdisk and parted let you specify the sectors, newer versions automatically default to a start-sector of 2048 (taking SSDs into account, which have similar needs) for the first partition.
