hi everyone... first off i wanna express that i am freaking out without my mba working ( shhh im on a pc)... so one day it started up and showed this blinking folder with a question mark... i tried the things everyone did online already by pressing command option p & r... i tried going into disk utilities but there i saw that the computer did not recognize the hard drive... so i took it to apple genius and they did their diagnosis too... it showed up also as the hard drive being the only issue... they charge 280 to fix it and replace anything that needs replacing... or i can go to OWC and buy another ssd for my specific mac and replace it... what do you think? would replacing the ssd solve my issue? because for 40 bucks more i would get about twice the size from OWC... thanks for your input
