Is 4K alignment of HDD/SSD very important? Can a disk be converted to 4K without data loss?
4K alignment of HDD/SSD - how important is it?
It can in theory slow down performance
In practice, if you had created the partition as NTFS, with Win7 or better, or the relevant filesystems with somewhat recent versions of Linux, it would have already taken care of the alignment.
Some software, like Minitool Partition wizard, AOMEI etc will allow you to align partitions. SSD software, like Samsung Magician, will allow you to do so on their SSD's too.

Turns out the created partitions were 4K aligned indeed.
