I need to extract data from a Hard Drive of a 2011 MBP that usually won't boot because of a seemingly broken drive. The computer booted on some attempts, but it usually shows a gray question mark logo and holding CMD+R boots internet recovery.
The MBP can be booted through an external USB hard drive with a copy of OS X installed on it, but only the external drive does shows up in Disk Utility.
I think it can be concluded that the main hard drive is damaged. This can further be supported by the fact that the
SATA/SATA Express tab in the system report shows Unknown under the first Intel 7 Series Chipset where the Hard Drive is meant to show up. Is there any way to extract data from this hard drive? Are there any special tools necessary? If so, then are they cheaper than bringing the laptop to the service shop?
