NVME upgrade Issue (ssd does not show up)
Hi guys,
I got stuck with repairing my imac.
Here is a little chronology:
- iMac 27 "from 2017 quit working, restart using long press on start button. Crossed-out circle symbol
- after reseach I came to possible defect on SSD or the OS
- reinstalled (El Capitan) via online recovery mode (cmd + R), updated to Mojave and Time Machine
- ran stable for a few hours, then the same symbol again and no operation possible
—-> opened the imac (that’s the reason the repair shop doesn’t take it to repair)
- a Samsung 500GB is installed on the PCI port
- Samsung out, Gigabase adapter and ADATA SX8200 Pro 2 TB (with control screw) in, hard drive looks a bit too high, but goes in ...
- added a isolation tape to protect the adapter from electrical short
- does not recognize sdd, not even with "diskutil list "in terminal
- open again, SX8200 out, Samsung EVO 970 EVO 2 TB in
- does not recognize sdd again, in online restore mode
- old Samsung (the original ones, if the previous owner didn't do anything) back in without an adapter, it is recognized (I guess I did not broke anything either)
- testing comes to the same problem. Reinstallation starts, but ends with the crossed out circle. Does anyone have any ideas about why the 970 EVO is not recognized? Alternatively, I could install a normal ssd. Everything is cheaper than buying a MacBook pro m1 plus monitor.
Thank you and have a nice weekend.
Is this a good question?
