I had a 600MHz/64MB/9GB laptop that came with Windows mistake edition. I managed to survive first year of uni on it by switching to Vector Linux, which was really fast compared to Windows. (Of course, it had issues playing sound from more than one source, this was oss days).

Then one day the hard drive appeared to die. I eventually realised the issue was located around the 1.5gb mark, so I recreated my Linux partitions after 2gb and it worked fine for the rest of the year.
