So, after few days working diskless, I am back to normal operation mode. About time, we are late with last episode of screencast ...
The copying of external disk went error free and took almost 5 hours (210 GB). Fortunately, the MBP was usable - I did not want to modify too many files, but it was perfect for Web research and writing in Google Docs.
After reboot, the TimeMachine decided that 85 GB needs to be backed up again. This seems like bug in TimeMachine, because I have not really changed much more than few gigs - 4-5 max during the few days.
Spotlight is also quite busy and completely confused - saying that I need to wait over minus two billion hours until it is done with indexing. That's pretty long - or pretty fast, depending how you see it :-)
