Last night I was working with an older HP laptop and things hit the fan very quickly. I discovered I couldn’t write a file to disk and before I knew it the system had thrown up to a black screen and needed the power cut to reboot. I immediately realized that there was a serious hardware problem. Then I spent the better hours of the evening trying to salvage everything from the old drive to a new drive, only to have the new drive seemingly show the same symptoms. It is a laptop of course and so I assume it’s the bus for the drives or the cdrom. I pull out the cdrom and it seems to behave itself just fine. This morning as I was checking the last of the package updates it dawned on me how different things would have been if it were a windows laptop. The laptop runs linux and when the system froze I immediately assumed it was either the hard drive or the drive adapter to the mainboard. Why?
