I bought a Samsung SSD 850 EVO 250GB for my MacBook Pro 13'' Early 2011, but am unable to install OS X to it. (Yosemite 10.10.3)
When installing the SSD internally, OS X doesn't find the drive, and diskutil reports the following (tested with Internet Recovery, old install on external drive and own thumb drive installer):
However, when attaching the SSD via USB (externally) the following is reported by diskutil on the same machine:
Partitioning didn't work, hangs on "Waiting for volumes to reappear…". After installing OS X on the SSD while attached via USB and reinstalling internally, drive is not found again. The old HDD works fine internally, but is very slow (constant beach balls, more that when used externally) and has a negotiated link speed of SATA 1.5 Gbps.
Any ideas? SATA cable broken? Chipset broken?
Thank you for your help!
