So the day I need to submit a major rewrite on my script the laptop suddenly starts flashing a folder sign. I go to our tech depot. and after having a heart attack twice (once for thinking I'd lost the hard drive and a bigger second one for thinking the motherboard was gone) they were shrewd enough to figure out it was the hard drive SATA cable. And then there was the whole ordeal of trying to find this part. God forbid you have an apple out of warranty. But then I Googled the part name and presto.
As smooth as one can go. Just followed the steps in the guide here. Started working in seconds.
I know where to go when something like this happens again.
