maybe, i was trying to figure out who started the whole 520B thing, but was difficult to find… only thing i did manage to find about it was that NetApp sold their own brand 520B sector HDD’s back in the day.
to my understanding one of their main selling points was the whole checksum deal…
ofc that doesn’t mean they developed it.
i suppose the platters are basically the same today, but atleast initially it wasn’t possible to format a 512B to 520B but you could always format a 520B to 512B because you aren’t forced to use the entire sector.
today i doubt the sectors are truly hardware limitations, aside from maybe the PCB on the HDD will have some standards it upholds.
wouldn’t at all surprise me if they had a standard “platter sector” type deal, so they can simply switch around the sectore sizes as they want…
ofc there may be some limitations, and performance related stuff to this also,
to my understanding atleast from the older versions of the tech, because you can go from 520 to 512 and not the other way around, then if your disks are 520B then you would ofc want to run them in 520B and if they where 512B then you couldn’t run them in 520B
i sure wouldn’t mind if my data wouldn’t get damaged from me moving it around… it’s why i got into all this storage stuff got so annoyed that after spending a lot of time sorting stuff it would end up degraded years later because i erroneously assumed that it was stored in a reliable way.
