I'm attempting to run the fsck command in single-user mode as part of my random maintenance (cause I'm too lazy to find my Leopard disk), but ran into a slight problem. When I plug in my USB keyboard for this (otherwise I use BT) the keyboard works fine. As far as I can tell every key works when the system is running, and there is no problem getting into single-user mode at startup. However, the keyboard no longer works once in single-user mode. I can't type anything in or use the stop process command (something like ctrl or alt and Z or X or C, I couldn't remember so I tried them all). I thought maybe the computer was frozen in single-user mode, but here's the strange thing, it's 'working'. If I unplug my external BT card, some error will report on the screen about the connection, and the same if I plug it in if it wasn't to begin with. So basically, I can boot into SU mode, the machine does not crash, but I can't type anything in. I don't have another USB keyboard atm, as the one I have is the backup to the BT, I do have a USB 2.0 PCI card which I tried with the keyboard plugged into it, as well as directly into the original USB ports, I tried unplugging all my peripherals except the PCI card (and keyboard). Any insight to this would be much appreciated! Thanks, EDIT: I don't know how, or why, but after attempting it again while using a powered USB hub (before the keyboard was plugged directly into the tower, no hub) I was able to successfully input commands with my keyboard in SU mode. Other than that, the only thing that has changed was a power outage which lead me to reset the PMU on my logic board. Strange and possibly unrelated, but I thought I'd mention it.
