Hi there, Just a quick question about how to correctly transport a PowerBook. Basically, I wondered if it is safe or even recommended to keep a CD/DVD in the drive while toting the PB around in my backpack? The reason I ask is that I previously had a Toshiba laptop which I also carried around in my pack (in a vertical position), and the CD drive eventually stopped being able to read or even recognise discs. I was told this was most likely because the drive had gone out of alignment, meaning that the laser head was no longer angled correctly to read a disc - and that this probably occured as a result of the drive mechanism being jolted around while in my backpack (while running for the bus, etc.). So, would keeping a CD in the drive while transporting my PB prevent a recurrence of this incident (ie. by lessening the potential movement of the internal mechanism), or might this actually cause more damage? Any insight or advice much appreciated! Cheers.
