Yesterday I woke my Mac (10.4.10) and checked USENET. In a minute it said I had disconnected a USB drive without ejecting it. A minute later the screen went dim and a sign told me in four languages to shut down.

I suppose that was one of those Colonel Panics I've heard about. An hour ago, just before putting the computer to sleep, I had disconnected a flash drive, and perhaps I'd forgotten to eject it first.

Could that have caused a panic a couple of minutes after the computer awoke?

E.Z.-

The one kernel panic I've had filled the screen with garbage text and locked-up the computer. It was caused by a broken ground wire in a USB mouse. I had no prior warning or opportunity to shut down. Your experience may not have been a true kernel panic as I understand it.

USB is a "hot plug-able/unplug-able" system. In theory there is no electrical damage done when connecting or disconnecting while power is applied.

Normally the message telling about an improperly disconnected flash drive is just a warning. The damage that might occur would be if the flash drive was being written-to when disconnected, and the damage would be corrupted data and/or format on the flash drive.

My panic log called it an unresolved kernel trap. Is that a panic?

I have in the past unplugged USB storage without remembering to eject it. The difference this time was that I put the computer to sleep before it warned me.
