Mac Air harddrive replacement.
1 - 2 horas
Hardrive had unrepairable errors.
I ordered the part 18:30ish (GMT) on the Friday evening, could believe it when I got home from work on Monday evening to find the new disk had arrived.
The next night I installed it with help from your utube clip explaining and showing the necessary stages. When it came to putting it all back together ...... no problems either. Powered it on and formatted and installed the O/S !!!!! ( I am now and Apple Engineer :-) or so I tell everyone.
Thanks for enquiring it shows you care. Please tell the girl in the utube clip if she ever in the UK and needs a place to stay she'd be always welcome at my house.
Many Many Thanks.
Mac Air users do not fill your harddrive over 95% for prolonged periods. It seems constantly writing and rewriting to the same blocks can cause corruption.
