Question: MacBook Pro hard drive not showing up High Sierra
So my 2012 MacBook Pro (Unibody, not Retina) was working fine on El Cap, but I wanted to upgrade to Sierra so I downloaded the update and started installing. As has sometimes happened to me before, the installer had some error or another and didn't complete the install, so I went ahead and tried the process again with a USB installer (I don't have any data on the computer so I'm not concerned about wiping the disk). However, now the drive doesn't show up in disk utility at all! I have tried the disk on another computer already running High Sierra to no avail. I know that the flex cables and logic board in both of these work, and I was able to start up the computer no problem with my other SSD. Any ideas would be appreciated, and if you need more information I can provide it.
MacBook Pro, macOS High Sierra (10.13.1), Mid 2012 MacBook Pro Unibody 15"
