My kinda work require to work on Mac platform and so far they
tends to be very very stable. But on that day.. yrs ago, it's HD
failed me.
*Sounds of thunder storm* Boooommmm
.......
As usual, after I made my coffee and settled down on my seat... I
switched on my office's Mac. As usual... the screen slowly lit
up..... as usual, the Mac would display a smiling Mac icon... NOT!
It displayed a sad Mac. Now, when a Mac boots up with that sad
Icon, it usually meant a major problem.
Following that, I heard a weird sound coming from the CPU. It's
likened the sound when you stir coffee in a cup... but in this
instance.. it sounds smoother and consistent. 
I rebooted the comp and wala..... but comp prompted tt the HD was
missing. I was like.."W....T.....F." WTF cos I the day before I was
rushing a pitch due two days later. On top of that, I was running
tight on a deadline for a publication. Geee.... my bak sai almost
burst into dam at that point of time.
