Drive issues after macOS 13.2 update

I am having the same issue. I have a Toshiba 2TB external drive that I use for Time Machine. It's been working perfectly until i upgrade to MacOS 13.2 on 3rd February. Now I cant see the drive in Finder, and when I access Disk Utility I can see the drive greyed out, but cant mount it - i just get the spinning multi coloured circle. I have tried everything on the internet to get it to mount but nothing works.

Interestingly I have a usb key 124 GB which is plugged in and that is still accessible - its like the developers have done something to prevent the external drives from working (the cynic in me says because its not apple so they have added restrictions to force us to buy their products only).

THIS IS DEFINITELY CAUSED BY 13.2 - THE APPLE DEVELOPERS NEED TO WORK OUT WHAT THEY HAVE BROKEN AND FIX IT. LOOKING FORWARD TO SEEING A 13.2.1 UPATE VERY SOON!!!!!!!

it seems that for you they are accessible in du. mine will not even appear in du.

it appears in safe boot, not with normal non-safe boot.

i've been on the fence about reverting back to macOS 12.5, maybe i'll do that and just stay on it for a while.

nevertheless i am curious to find out what is actually causing this problem ... there must be some dameon or script that is broken in 13.2.

it is not just with this one SSD that i have the issue, i am trying to get a flash drive to mount and that will not either.

it is counter productive and prevents me from using my external drives to copy/move and access files i need.

Exact same problem on Mac Studio M1 max with OWC mini stack. The SSD mounts and works normally. The 8TB hard drive does not mount or show in the disk utility. Mounted ok and accessible after safe boot but resumes problem when followed by a normal restart. worked great in 13.1 Need Apple to fix this!

Have the same issue foolishly updated yesterday, and now my Promis Pegasu R32 and one of my Qnap TR-004 do not mount. Drives show up in the disk utility as individual drives and Promise Utility also recognises them but cant get them to mount. One is my TimeMachine Drive one has tons of the Videos Im working on I need now.

2017 iMac 27" - Upgraded to Ventura 13.2 on 1/30. Kernel panic crashes started immediately after upgrade. Disconnected external drives and crashes stopped. Western Digital 6 TB My Book drive used for Time Machine is completely bricked. Tried Disk First Aid in normal mode, safe mode, even tried connecting to my 2013 iMac at home running Catalina. No luck. The drive actually crashed my home iMac with a kernel panic. Tried connecting to office PC. Drive not recognized. Thank God this was only a Time Machine drive!

So what to do now? I'm taking my machine back to Monterey. Never thought something in the OS could render an external drive useless. It'll be very hard to EVER trust Ventura.

The 8 TB hard drive in OWC mini stack will now only mount (2 TB SSD on same connection works fine) after a fresh install of Ventura 13.2 and then only the first startup after that no show in safe boot, normal start, or replugging the cable. tried different new user login, cache cleaning and removing all login items; no joy! Etre shows no major problem. frustrated

Did all the steps Phillips recommended. Disk did not mount in Safe mode or with a different user login. Être pro found no major problems. The only way to get the disk mounted is to do a fresh install of Ventura 13.2 and then it only mounts on the first login after that it fails to show; would go back to 13.1 if I could figure it out.

nice to know that a fresh install of 13.2 worked.

i personally dont like how macOS 13 is changed vs the previous versions, they made it resemble their iOS platforms to accommodate Apple’s chips in their computers, but mac computers are still not touch screen capable.

either OS version you choose, up to you. i noticed they improved some underpinnings in 13 that were chronic in 12, but it never fails that new bugs appear when that transition takes place.

they say macOS is good, but software clutter-wise is on par with other OS’s and you still find yourself with some old creaks and cracks left in it, even after a major software jump.

in recent years i found my other installations of competing brand OS’s hold up better in this regard.

for those on this latest Ventura update and using macbooks/pro’s … how has battery life been ?

when on Ventura i saw battery drain quicker on my 2019 intel mbp i7. on Monterey drain is more predicable and battery lasts longer between plug-in’s.

same here and it is REALLY setting me back on my work.. still haven't figured anything out

also noticed now that non of the SD card readers in my two Thunderbolt 4 docks (cal digit) works anymore this is a joke apple

OWC is aware of my situation as well, but I think it’s an Apple issue since 13.1 ran fine
