and iirc on SSDs you cant really a file with random bytes. Apple removed the "safe erasure" option from Finder because they couldn't guarantee deletion.

- AstralStorm 9y agoYou can, but ssds are internally log structured, you have to overwrite whole free space plus the reserve and then run a TRIM.
- angry_octet 9y agoYou can't overwrite the reserve directly though. You have to write non-zero data to 99% to lock it, then destructively update the last 1% many times to cycle through the reserve. Many disks have a full erase command, which asks the internal controller to do the erase. In general though, I use a hammer.
