IMO the only way to perfectly protect yourself against Ransomware Attacks is with CD-Rs, because it's something not even hardware can alter. A skilled take over of the root level of a machine can be encrypting everything and you'd never know it, until the day it denies your access, by deleting an encryption key until you pay up to get it back...you hope.

Disk drives used to have a write-enable jumper on them. No more.

Drives? I havent seen one yet. Floppies yes, but just like SD cards its just a plastic piece being read by controller GPIO and a mere suggestion to the hardware.

There are forensic Write blockers for drives tho starting at around $200 for SATA/IDE solution.

Some of really old SCSI and (I think)IDE HDDs did have "WP" jumper positions. I don't know practically how it was implemented, though.
