One for Randy: Failing SSD
¿ªÔÆÌåÓýIf the drive mounts, you could use a tool like DriveDx to check the SSD¡¯s Lifetime Left. Might shed some light on its condition.

I have this 2 TB Samsung EVO 870 SSD that is use to make a bootable clone of my internal hard drive before I do system updates - so I can go a step back if anything fails.
And today I was going to make a update from 15.3.1 to 15.3.2 So I attach the SSD, open Disk Utility and erase the drive before I start cloning Except - today it wouldn't. It fails. So I tried to erase all containers and volumes one by one. No luck. So I tried to format it as macOS Extended - no luck FAT32 - No luck. Nothing works. And then in the back of my mind, I seem to remember Randy writing about how to revive a failing SSD - and if I remember right, it would implicate using a PC? I can't find the post on this list ... but I'd hate just to throw this SSD in the bin. What to do? Any help out there? :-) Peter |

OK Randy, I have obviously remembered wrong. It must have been someone else then :-)

As I recall it was something about ¡°resetting¡± an SSD after extensive use, where it had been filled up or something, and there is no Mac software that can do that, but apperently there is software for PC. Disk Utility will not format it. Period. Maybe it¡¯s just garbage. Annoying! :-) Peter On 20 Mar 2025, at 11.36, Randy B.

¿ªÔÆÌåÓýNo, the problem is, that is was working perfectky ¡. untill I tried to erase it / format it.? I can¡¯t seem to do that, so I was just looking for ¡°other ways¡± to TRY TO erase/reset/revive it? :-)

You repair an SSD by running First Aid. If First Aid doesn¡¯t fix your SSD, you are SOL. There are no third party tools for the Macintosh to fix an SSD. __________________________________________________ Randy B.

Just out of curiosity, how old is this drive?
