HD does not unmount booted from Ext HD
Normally no problem; recently boots but error notice: "cannot unmount disk; close all applications & files". I re-installed last update to 10.6.3. Trying to find anything that could be open, deleted some apps, etc. So far, nothing works.
Is there a simple way to find any open apps or files I haven't found? I do have Time Machine set on the ext. HD but haven't yet restored from last month to see what changed. Tried booting from 10.6 install dvd. Same answer from Disk Utility.
Is dit een goede vraag?
