Edit: feedback
Thanks for all the advice! Here's some funny feedback: it was a faulty drive 🤣 give me back my feelings 😭 obviously I'm sending it back
I have just received my Seagate 18TB IronWolf Pro HDD and the specs say that the logical sector size is 512 emulated. Moreover, Seagate says that switching to 4096 sector size is as easy as doing a quick format (Windows terminology?). I suppose on Linux this simply means creating a filesystem with that block size? For instance mkfs.ext4 -b 4096 /dev/device or - in my specific case - cryptsetup luksFormat --sector-size=4096 and then creating a file system?
What confuses me is the Arch Wiki article on advanced format that has instructions on how to use hdparm to tell the firmware to use a certain sector size.
Do I need to do the hdparm thing, which seemingly conflicts with the Seagate instructions?
Totally unrelated, but I just want to say that my 14 TB sas drive (exos?) was brought back to life in a 12 TB configuration after failure by using openseachest to deactivate one side of one of the platters (the failing one, it was the only one with errors) after I told it to start it took 4 days to reformat, most of that time reporting no progress, but finally finished and now it works great!
