I used to have a tool from hgst/wd to 'convert' drives to 4Kn, but after a mentally challenging interaction with some wd support, I decided to try and use other solutions mentioned on the internet this seems to produce output similar to the previously used tool sg_format --format --size=4096 /dev/sdd Anyone have experience with this? This is first time the drives are already in the nodes, so I don't have a power cycle on them.

Anyone have experience with this? This is first time the drives are already in the nodes, so I don't have a power cycle on them. Depending on the drives in question; this may work.
However I would also suggest looking at Seagate's OpenSeachest tooling. There are some very valuable warnings in the docs (summarized here): Any power-loss partway through the reformat may because the drive to become inoperable - sometimes permanent, sometimes recoverable with another successful sg_format call. -- Robin Hugh Johnson Gentoo Linux: Dev, Infra Lead, Foundation Treasurer E-Mail : robbat2@gentoo.org GnuPG FP : 11ACBA4F 4778E3F6 E4EDF38E B27B944E 34884E85 GnuPG FP : 7D0B3CEB E9B85B1F 825BCECF EE05E6F6 A48F6136
Hi, I've played with these settings and didn't notice any benefit. Tools for changing sector size on HDDs are pretty terrible and it's really easy to brick your HDD when using incorrectly. I wouldn't recommend. Best regards Adam Prycki W dniu 30.01.2025 o 09:52, Marc pisze:

Yes I can remember testing this in the past, also did not see any difference.
