First of all I want to thank all the people on this wonderful board.
Short description of my problem:
Long version:
During a battery swap I was deciding to change my SSD as well because my technician offered me a pretty good deal.
I took the 500GB option. Since I had used WD spinning drives for decades and never had one drive failing on me, I decided to try a WD-SSD.
For about two month I was a happy camper. Until a Linux dual boot experiment went south and I decided to nuke the entire system. Doing that I started to get SMART errors and I was not able to reinstall the System.
Nothing helped. I was recreating partition tables, deleted & created APFS containers, tried it with HFS+, did a PRAM and SMC-Reset, booted into single user mode and even created a new partition table under Linux with fdisk. No success!
Sure enough - when I was plugging in another NVMe SSD I had no SMART Error.
But I had luck and my technician was able to reproduce my error and send the SSD back to his supplier.
Since this can take quite some time I decided to get another SSD (same model) and use the later replaced one as spare.
With the new SSD I had no SMART Error and the installation on the new WD-SSD worked fine.
Everything was good again until the 2nd SSD started to fail as well.
This time I realised that my apps started to freeze and everything became slow. A few moments later the screen went dark and I got the question mark in the folder.
This time I am not even able to format the broken drive. Even worse my computer needs at least 10 Minutes to even detect the drive.
It goes without saying that this disk has SMART errors as well.
Bottom line: two broken SSDs and I have no idea why.
Theories:
- The SSDs were broken from beginning on: For the first one it’s possible since my technician used an USB enclosure plugged into another MacBook Air while changing the battery of mine. Most USB-enclosures don’t support SMART so the Installer would not detect a SMART error. I own the same enclosure and tested it with the first broken SSD and the installation would have been possible. The 2nd SSD was fine at the beginning since I connected it directly and got no SMART-errors. - It is possible though that both SSDs have some kind of defect that leads to such short lifespans. Maybe a bad batch from WD and since my technician is not selling a lot of them I could imagine that I just had bad luck. The supplier already replaced the first failed one and so far its fine (I did not put it into the MacBook though).
- The Macbook is broken/is frying the SSDs due to some technical defect: My Apple SSD is working fine for years and since these SSDs are (from what I understand) not so different from “normal” NVMe SSDs my MacBook SSD should have been fried by now. But it’s still working fine and I don’t have any SMART errors.
- The adapter: As stated before I use a generic adapter and not the branded one from Sintech. After the first SSD was breaking I also replaced the adapter.
- Heat? I am living in Indonesia and it can get pretty hot in here but in both cases I was in climatized rooms when it happened.
- Missing firmware Update? I realised that the 2nd and the replacement SSDs have not been updated so I assume the first SSD was not updated as well. But could a missing updated cause such damage though?
I really hope that somebody in here has any idea what the problem is.
Maybe there are some users in here who used the same generic adapter I used (nfhk n-914a)?
And how reliable are Western Digital in general?
Did anybody in here had similar issues?
Is my MacBook broken?
Thank you!
