Rapid Unscheduled Mentality Disassembly

I will never be comfortable using /dev/sda as a target for dd no matter how long I use NVME drives.

THEY’RE NOT SCSI. EVERYTHING IS A LIE.

Yeah, what's up with that? PATA used /dev/hd* but SATA for some reason uses /dev/sd* instead.

They re-mapped it to all be in /dev/sdX after the SATA drivers in the kernel just kind of took over from IDE as the primary "type of hard disk" likely to be encountered. I think somewhere in the 2.6 kernel series?

That's also why the old driver has "DEPRECATED" everywhere

@CursedSilicon @argv_minus_one @rk @prettygood sd* are scsi disks which also include sata and usb mass storage disks due to both being built on the scsi subsystem in linux

sr being scsi rotational media like dvds, st being scsi tape

@CursedSilicon @argv_minus_one @prettygood @rk it’s not a perfect mapping since sd cards are either sd if the reader is usb-based or mmcblk if not
