If one unmounts a disk, is that disk still available for write and can the following sync do anything?
Some people follow their GPS into the drink, and other people ask spicy autocomplete how to admin their computer.
One only relies on ChatGPT for 1) imagining science fiction story lines and devices 2) Only where one knows the correct answer already. This instance is kind of a one-off. Spicy autocomplete - lol : ^ )
I was under the impression that the sync command makes device removal safer somehow. Even though the device was unmounted, there may be cached data that wasn’t written yet. Could be wrong about that, but it seems harmless to include.
Edit: looked it up, and umount calls sync, so there’s no need to include it. And if you do include it, sync before umount, like you said.
Uhm, been a while since I had to think of this but pretty sure you used to need to do that the other way around. Sync before unmount, else things may still be being written to disk.
