Use sg_format to run a low level format on the disk. 512E vs 4kN isn’t going to change much in a homelab environment. If you create a filesystem with 4k clusters, Linux will send 4k wrudte blocks to the disk. The firmware on the disk will write that out into 8 logical disk sectors, usually in a single 4k physical sector. I use my storage mainly for media and there’s no performance difference between my 512E disks and my 4nN disks. I simply don’t have an intense and sensitive enough environment to show the performance gain. I’d say leave the low level formating alone and just write a filesystem on top of it with 4k blocks.

Technology@lemmy.world•Generative AI Is an Engineering Disaster. A shockingly inefficient trillion-dollar project.English
3·9 days agoThat’s an interesting thought. Genetics is largely a mixing and copying process with occasional “hallucinations” in the form of transcription errors. Most of these errors result in the termination of the hallucinated code. Hallucinations that damage the termination process result in cancer. In the larger sense of evolution, there’s a robust external “review” process. Environmental pressures, predation, and resource availability weed out most of the mistakes and selects the results most likely to succeed.

142·9 days ago“Generative” is a misnomer. It will never generate anything new, it can only regurgitate existing ideas based on patterns that already exist. It’s very good at pattern recognition and summarizing, but lacks the ability to form a distinct new idea.

Well, it’s roughly the size of a two-year old child, if the child were liquefied. It’s a real bargain!


Low level formating is how the data tracks are layed out on the disk platters, it’s what the drive firmware sees. hdparm and sg_format instruct the disk to rearrange those tracks. High-level formatting is what the OS sees when you run mkfs. It creates a new file system or replaces an existing one.
