Hello Guys, i have installed a used 256gb SSD to my Macbook Pro 2012. Now when I boot my system via recovery disk it shows on 8.13 GBs and not 256. I tried booting it with the old SATA as external drive; it worked but now i am unable to see the installed SSD at all. Disk utility is only showing external drives. No idea what to do. please help.

Have you formatted the new drive?

If you installed the SSD internally it is not being recognized— did you also change out the SATA cable? This is a known point of failure.

I have formatted it but no use. Or probably I’m not doing the right steps.
Why are you showing me the external drive?
That looks like the installer...
That’s the issue. The installer bootable usb is only 2gb that contains recovery disk assistant. I have selected the volume on the left panel and formatted it.
No actually. I just replaced the HDD from SATA to SSD. No change of cables.
