align Samsung harddisk

Samsung Electronics offers Samsung Alignment Tool (Software) with the Samsung 4K sector HDDs.
This program is only required for OS prior to Windows Vista, or an operating system backed up and
recovered with an image copy software (cloning software) that does not enable 4K sector drives.
(Note: Hitachi got a similar tool) 

With the provided tool "AcronisAlignTool-Samsung" you can check and realign your partitions.
To see if your partitions are aligned  correctly go into system Information and check if the "Partition Starting Offset" for each partition can be divided by 4096; this should return an integer value.
(example:  1048576/4096= 256)
