Disks not mounting: com.apple.DiskManagement.disenter error 49180

[Kebabselector]

Odd one on my Mac Mini this morning as none of my drives other than my boot volume are mounting.

The internal SDD (boot) is all fine, but the internal HDD isn't. Also neither of my USB/Thunderbolt drives appear.

In disk util they are present but the error 49180 shows when I manually mount the volumes.

I've booted in to the internet recovery console and checked the volumes and they appear to be o.k.

Only thing I have done recently was allowed full disk access to Carbon Copy Cloner which I have now revoked.

Help!!!

I did speak to Apple Support who suggested I attempt to re-install the OS (after trying a number of things).

Now I have a Mac Mini that doesn't boot!!

What year MacMini? So you did the reinstall? How? Doesn't boot - what happens?

I'm experiencing the same error 49180 when I try to mount unmounted devices on disk utility invoked from USB recovery disk. Mine is a cMP 5.1 running Catalina 15.1. Stopped booting when I did PRAM reset at startup. Everything was running fine up to this point. PRAM reset was done to try to fix a minor annoyance with Mac Mail.

The entire internal and external volumes show up as greyed out in disk utility (unmounted). I'm sure it's some simple setting tweak but I don't want to go through unnecessary fix to dig the hole even deeper...

Are all these disks on HFS?

 

[WCH0058]

No, some are APFS: Further development - using Mojave installer, all the disks were mounted. I restarted on Mojave and all seemed ok until the screen just blacked out after about 10 minutes. I'm wondering if PSU is the issue.
GPU, by the way is Sapphire Pule 580 connected via 6-8 pin converter. I can't determine whether it's the GPU or PSU, but since the recovery mode is working without a hitch, GPU might be ok?

When it went dark, it looked and sounded as if it was struggling to get power. Could it be power supply going south?
Doesn't explain why on Catalina my drives are not mounted as opposed to Mojave showing everything.
I also checked PRAM battery and it was measuring healthy 3.15V.

It's a 2012 Mac Mini - was advised to boot into internet recovery and reinstall. it seemed to going o.k. but kept erroring after about 30 minutes and stuck in a loop.

In the end I wiped the SDD and reinstalled the OS and restore the Time Machine backup - it seems to be all fine - lost a few emails, but to be honest not a big loss.
