    After the restore, the starting sector is different.
    (Hard Disk Manager 12 Professional Build 10.1.19.16240_000 PE Version)

    Is it a bug?
    There is no problem on Linux Version.

    If you divide the starting sector numbers by 4096 the restored ones result in a whole number, not a whole number plus a fraction which happens in 2 and 3 of the original. My guess is that Paragon is aligning the partitions to a boundary which is what you definitely want for SSDs and I think it can be a slight advantage on a mechanical HD.

    Is there a setting in the restore that is something like "use Vista alignment"? Turning it off if you can may give a different result - I've never tried.

    As for the Linux, I don't know.

    Thank you for your reply.
    It occurred regardless of Partition Alignment Mode.

    Can you clarify the sizes of the Disks? or was this a single restore back to the same disk?
