Hi,
I have a (mid 2012) Mac Book Pro and decided to upgrade the original HDD to an SSD. I purchased a Samsung SSD EVO 850 and I'm encountering the following issue:
I removed the old HDD and replaced it with the new SSD. When using the Disk Utility feature, I get the following error message when selecting the Erase.. option:
Disk Erase Failed
Disk Erase failed with the error: Wiping volume data to prevent future accidental probing failed
I had the Format: option set as MAC OS Extended (journaled)
What I did notice is that it gets stuck at "Unmounting disk" and doesn't change until it errors out.
What I decided to do was to put the old HDD back in, log into the system (tried on both Lion and El Captain) and connect to the SSD using a removable docking station. Doing it this way I was able to format the drive and create a partition (using GUID) without any issues. I could see the disk had successfully mounted. However after I did this and took the old HDD out and put the new SSD in and checked Disk Utility, it didn't recognize the new partition I created. It appears as an unformatted disk. If I repeat the same steps to Erase the disk I get the same error mentioned above.
If you require any further info/details let me know.
Thanks
