I make a random 1MB chunk, then write that all over the drive, at overlapping offsets. I've been told that really clears it. On IDE-spinning-rust disks I trusted it, not sure if I should trust these modern SSD
- p1mrx 1y agoWhy rewrite the same 1MB chunk, instead of making new random chunks? Redundant data at least opens the possibility that the drive could deduplicate.
- edoceo 1y agoCause making new random was taking too much time.
