Problems with mac mini and satechi stand & hub

Just had a look at my instruction manuals where it suggests using a 5v 1A - 3A phone charger.

I have loads of those!

That is not enough, you can check the USB mA demands in System Report, but honestly, get a PSU.:)

A USB3 port can supply 900mA max, connect 2 898mA drives & guess what happens.

If the hub is only powered by the Mac mini, then there is not enough power to support multiple external drives.

What I would do, is plug one into the hub and one directly into the Mac mini.

Troubleshooting Lagging Mac Boot:

A. Try Safe Mode:

In Safe Mode, login items do not run, and corrupt system files(i.e. caches) are intentionally reset as a way to fix issues

1. Boot: in to Safe Mode: [Hold Down: shift key upon boot].
2. Log in: as same user
3. Wait: 30 seconds
4. Restart; your Mac
5. Log in: as same user

B. See if your Hard drive is Failing:

What to Try:

• Verify your Drive: Repair your Disk in Disk Utility - Apple Support
• Go Here: If your Mac Starts Up to an Apple Logo or Progress Bar - Apple Support
• Perform the following in Recovery Mode:

1. Boot: into Recovery Mode. Go Here:  How to Use Safe Mode on your Mac- Apple Support
2. Select: Disk Utility
3. Select: the Drive
4. Click: First Aid button

C. Single-Out this User:

Try a pre Administrator user, seeing if you do not get this occur while in it. If so, then it is an issue with the configuration of the current user. If not, then it is an issue with the entire Mac, in which case you should reinstall the macOS. See below...

I think den.thed is on to it, I've never had a bad powered USB Hub except if the PSU or cabling was bad.

Check System Report>Hardware>USB for mA usage & availability...

I think you have nailed it.

My cheapo hubs have power input sockets but I have never bothered to buy a power source . . .

Does your Satech have a Power supply, it really needs one.

This appears to be a common problem with all USB hubs both on Windows and Mac machines.

Take a look at the reviews and you will see what I mean.

I have never had one of those Mac-mini dedicated hubs but have several cheap (£10) ones which have always ejected themselves from time to time . . . some quite regularly.

I used to put it down to them being cheap but as time went by I realised that all of them, regardless of price have that tendency.

It occurs whether I have plugged in an HDD, SSD or memory stick. I have 3 different computers but they all do it.

You're welcome, anxious to hear good news!:)

What external drives are connected to the Satechi hub..?

The operating system is up to date macOS Sonoma 14.5

Disk Utility doesn't show any notifications or anything.

The macmini's ports are completely fine.

An apple expert indicates that the hardware is fine and something must be wrong software-wise.

The shutter time is set that when my monitor goes into shutter time that the peripherals stay on.

Does anyone have another idea, how to solve this problem?

This sounds more like a power issue with the Satechi hub than a software issue.

I would test the setup with one less external drive plugged to the Satechi hub.

Or.. move one external drive from the Satechi hub and plug it directly to a port on the back of the Mac mini.
