The same thing happened to me and it took me hours to get here. After hours and hours of reformatting the drive on my iMac using an external SATA cable (3 external SATA cables to be exact), I could not get the partition to show up un-greyed. I knew all 3 cables could not be faulty but there was no other explanation why the MBP would not recognize the new formatted internal drive. On occasion, during my multiple attempts to format the drive as internal in the mid-2012 i5 2.5GHz 8GB the drive would show up in Disk Utility but every time I tried to format it as an internal drive I would get the error “wiping volume data to prevent future accidental probing failed”. I tried an old HDD I know worked less than a month ago and still I was no closer than I was 8 hours before. Kept getting the same errors. I came across this guide [https://blog.macsales.com/43010-how-to-format-a-new-internal-ssd-in-macos-high-sierra|https://blog.macsales.com/43010-how-to-format-a-new-internal-ssd-in-macos-high-sierra] and I just replaced the SATA cable. I didn’t think that was the issue because I was getting all of the other error codes. Replace the SATA cable and save yourself 8-10 hours of research. Thanks for the help!
