As Manuel already stated, you have disks with 4K sectors.
Could you expand a bit further on those tools :-) ?
All I know is from reading about it, it's called "Acronis Alignment
Tool", also available from certain drive manufacturers for free.
Are they NetBSD ported ?
It comes as a stand-alone ISO image you can boot from when burnt to a
CD/DVD. No port necessary. It will rewrite your disk(s), so can take a
huge amount of time.
CLI tools ?
No, it seems to have a graphical UI.
Work on booted/running drives or need to be invoked before/during
boot ?
You will have to boot it instead of your favorite OS. :)
The main problem I see is that the tool could be limited to FAT/NTFS,
i. e. the Windows world, and it will probably not work well with
NetBSD's concept of disk structuring. But you would have to find out.
You can probably save a lot of time, tries and headache by doing a
fresh installation of your server with correct alignment and block
sizes... :-|
