Unable to Format SSD

[michaellong]

My friend gave me his 2013 Macbook Pro to fix and when I turn it on, a file with a question mark comes up. So, I pushed command+R to try and reinstall OSX. I am unable to see the SSD when I try to install OSX. So, I tried reformatting the SSD, and I can see the 512 GB SSD when I try to format the drive. However, when I try to format it, I get a message saying, "Unable to write the last block of the device." Does this mean that the SSD is bad? I have tried removing it and placing it back in. I just wanted to get some opinions first before I tell my friend he either needs a used $200 SSD or a new $500 one.

Do you have a macOS bootable USB installer? Or another drive, you can use to start the MBP with? If you start up from a different drive, you will be able to see if Disk Utility will see the drive, repair the drive, and format the drive.

Go into Recovery then Disk Utility there and run repair Disk and see what is reported.
