So to make a long story short, I replaced the hard drive with an SSD and I can’t seem to install Mac OS since
1st problem: after removing the hard drive, I realized that my data to usb cable was broken. Good start to the day.
2nd problem: recoveryOS keys get into internet recovery for some reason. After entering internet recovery to install El Capitan, it will show apple logo for 1 second, then go to prohibit sign and folder with question mark. Awesome. Resetting NVRam does not help.
3rd problem: Using actual shortcuts for internet recovery gives error -50101F after loading files. Awesome.
4th problem: After creating a USB installation of Big Sur using a terminal and another Mac it loads correctly but then in the middle of the installation it comes up “An error occurred while loading the update up to date.” I thought the problem might be the drive was using Mac OS Extended as the file system, I formatted the ssd. It kind of took an absurd amount of time. Then I used the first aid tool inside to check. There was nothing wrong. The same error occurred after formatting, failing approximately 12 minutes until the installation was complete.
After running the diagnostics, the code VDH002 is displayed. From what I understand, this is just a common error while installing third party ssd on Mac?
Anyway, due to the ssd working flawlessly, I feel like the Mac installation kind of messed up my SSD. Pretty . I ran some tests in Windows PE, and there is an absurd amount of bad sectors. More than half of the sectors are red. For an SSD of this age (less than a year and a half of use (i.e. sitting in its box and plugged only into a computer when used for Windows installation), this does not shouldn’t happen.
Thinking I messed up something, I used the dd command to write 0s to the drive. It went well. But that still hasn’t solved the problem.
I then changed the drive from MBR to GPT. For some reason, outside of Windows Diskpart, the disk turns into MBR. Anyway, after testing the drive for errors, none are found. Hooray! ahhhhh ,,,, no. Mac OS always fails, then something interesting catches my eye: ssds are not writable. WTF?
Then after looking in the system info of the USB installation, I can see that the ssd is recognized perfectly.
For some reason an attempt to restart shows a new boot option, windows. On entering, said option simply says something like “No valid boot device found”, “Enter boot device and press any key”, etc. clues?
Basic specifications of this Mac mini:
i5 4th generation
8 GB RAM
Kingston A400 ssd (after upgrade)
