Hi, So its been a while since I last posted. Hopefully theres some help out there My macbook pro froze, crashed, and when it rebooted i had the dreaded Question mark folder screen. So attempted internet recovery, and it ccould not see my hard drive. Not able to check in another machine if its ok, or if it died.. So ordered a new drive, installed it, and ran internet recovery again. nothing, couldnt see the drive. Reset Npram.. and finally, it was there. Then went to start the install, format etc etc, an error started it couldnt write to last sector, and it stopped.. rebooted, tried again, couldnt find the drive. reset Npram again,, still nothing.. im out of ideas, and searches just tell me to do what ive already done.
