@Woodswalked @Melissabeartrix Back in the day, I had a friend who used SCSI drives and would frequently hot-swap the connections.

"You're supposed power those off before swapping the connection," I said.

"Yeah, I know they *say* that," he said. "But I've never had a problem."

About a year later, I saw him again and he was powering everything off before swapping the connection.

"Oh!" I said. "I notice you're powering those off before swapping them out now."

He grimaced. "Yeah."
