This disk has S.M.A.R.T errors while installing Monterey

I have the same issue on my 2015 13" MacBook Pro.

My SSD has been replaced with larger aftermarket SSD though so I wonder that's related. Are you all running non-Apple drives too?

I'll be waiting a few weeks as I expect Apple may fix this sooner or later.

Glad you found a workaround well done I bet you’re pretty chuffed right now. Although having said that it sounds like a whole lot of work, I think I’ll just wait for Apple to fix it their end. I can wait a few weeks, I don’t think there’s anything groundbreaking on Monterey anyway.

E-X-A-C-T same issue, mid-2017 iMac and tried all the prescribed steps to remedy. I've also had multiple calls w Apple Support and spoken w several support specialists....each has claimed that I'm the first to report this issue. They've had no explanation for why the install identifies a SMART issue but disk diagnostics indicate no issues whatsoever.

If it were a true SMART issue, it seems like the CPU should be failing in noticeable ways and on its way out....but I see no issues and have been using it daily since first getting the SMART error/warning over a month ago.

After coming up empty, Apple support's only suggested next step was for me to need to take my iMac in for a physical inspection......which is never convenient.

Any luck on your end getting Montery installed or riding yourself of the SMART errors?

I was hoping to hold off until the 27" iMac M1 shipped.....I have a 2017, so I don't feeling like investing too much to fix it. However, seeing as it's yet to be announced and June is likely the soonest we'll see it.....I don't like my chances of just hoping it doesn't fail during the interim.

Do I run an external SSD or bite the bullet and get a new 27" iMac now?

So. My hard drive is an original 3 TB fusion drive that Apple installed in my 2017 iMac. I have not tried again to install Monterey. I thought I'd wait now for a couple revisions to come out and then see if the problem was resolved in the updated Monterey version.

Hardware errors don’t go away, as a general rule. But it’s clear at least some of y’all have a far higher tolerance for misbehaving hardware, and with somewhat less concern around the risks of data loss, so I’m not sure why y’all are concerned about these SMART storage warnings here. Run this hardware until it fails. Then deal with the outage and the recovery. These diagnostics are a warning; a prediction. If y’all choose not to heed the predictions, well, it’s your data.

That’s simply inaccurate. I’ve run every diagnostic program and nothing else except for Monterey installer says I have a problem. You would think something else would show a problem. Besides I have Time Machine backups.

Thanks for the useful comments. The CCC clone was bootable right away presumably because I'm on macOS 10.15.7. I have also made a TM backup on a separate drive out of paranoia now too though. I attach the DriveDX report, can't interpret it myself so any help is appreciated.

Thanks very much for taking the time to look through the report and interpret the major red flags. I had no idea that a failing SSD on my machine would also entail changing the entire Logic Board. The cost of repair is probably not going to be worth it and currently there's a supply problem with the latest MacBook Pros in my area so looking at 4-6 weeks to order a new machine. Will keep regular backups in the meantime.

Exact same problems here, Mid 2017 iMac 5k, exact same SSD. I had problems with it within months of purchasing it. Apple did fix it in store (back in 2017) but they used a diagnostic mode I'd never seen before. I think this is a similar problem.

Mine is the original Fusion drive that Apple installed.

it's a somewhat complex solution, i have the same problem, my mac is an air 2017, i thought this new version of monterey would solve the problem but they still haven't solved it

Also, can some SMART errors be fixed by formatting the disk?

Same problem here with a fusion on a mini. Maybe Monterey doesn't jive well with fusions?

I actually think this is a Monterey problem more than a disk problem. IF I run Disk Utility's health check it says everything is fine. Only Monterey seems to say something is wrong.
