Cd drive working hard during permissions repair
I am trying to repair permissions on my old 2007 iMac via the Snow leopard install cd. The time remaining text gets to 1 minute and then the bar stops moving and the cd drive starts working quite hard. That has lasted an hour now and he mouse clicks do nothing, though I can move the cursor. Should I leave it and let it work or has some sort of crash occurred?
iMac, Mac OS X (10.6.8), 1gb memory
