Incidentally – and apropos of diddly-squat – the other week I found out what happens when Mac OS X runs out of hard disk space. Not, I hasten to add, on my machine, but on a colleague’s five year-old iBook running 10.3, on a 10Gb drive, bless.
The short answer is: not a lot. It refuses to save anything, obviously, and everything goes veeeery verrrry slooooooowwwwwwlyyyy, but it basically keeps running. Which surprised the hell out of me.
The owner was marginally less surprised, but then, she had been clicking ‘OK’ every morning on polite little dialogue boxes telling her that her startup disk was terribly terribly close to being full. For six months. In the end, we managed to reclaim 3Gb simply by shifting all her music off, backing up her Entourage mail database, then letting the poor iBook crunch away for three hours repairing and compacting said mail database, and finally putting all the music back on.
Yes, 30% of her drive was taken up by fragmentation in Entourage’s monolithic database. Nice as it is, I remember why I stopped using Em@iler all those years ago…
