HDD/SSD Docking Station keeps ejecting

[Conflict]

Hi all,

Have an issue i’m facing and it’s as follows:

Basically I have a HDD DOCKING STATION which runs on USB3.0. Dock Station: https://www.orico.cc/usmobile/product/detail/id/3551
It’s brand new, works on its own DC adapter (not powered by bus) and works fine with a brand new iMac which is running on USB 3.0 as well.

When it’s plugged into an older iMac which runs on USB 2.0, it constantly gets ejected. Can’t even read the files inside.

From my understanding and researches from online;
- Constant ejecting could be bus powered related issue, but it runs on DC so shouldn’t be.
- Faulty mechanisms: eliminated also as it works with the new iMac.
- USB2.0 ports are not faulty, working well with normal thumb drives, bluetooth mouse and etc
- Doesn’t USB3.0 work backwards with USB2.0?

What’s the sorcery or explanation behind this anyone knows?

I've attached the hard disks via images.

*New iMac is 2017 - OS Catalina
**Old iMac is 2009 - OS El Capitan (Vintage), i’m trying to clone all files and port over to the new iMac
***MacBook Pro Mid-2012 running OS El Capitan is also facing same problem

Some drives have "sleep" circuitry that spins down the drive if it hasn't been accessed in a while. Unfortunately, when that happens and the system asks the drive "Are you there?" it gets no answer as the drive has to spin back up to speed and the query times out. The system then thinks the drive is disconnected (since it didn't respond in time). Nothing you can do about it unless the drive is configurable with some utility from the vendor to set it to NOT sleep. Never seen one of those, it's theoretical. There is an app called Amphetimine that can be set to keep the drives awake. it's in the Mac App Store.

Hi MacInWin,

But it works for newer iMac. It’s quite frustrating as I’m trying to clone files from my old iMac to the new one with this dock.

Is it due to El Capitan OS? Does this “sleep” issue happens to that and can the app you recommend rectify that?

It's not the OS, and I can't say if it's even definitively the sleep issue. It's just one of thousands of things that could be causing the issue and one with a quick solution. It could be hardware in the older equipment, tolerances in the timing circuits, looser physical connections in the older hardware, it could be the dock or the drive or the cables or the USB2/3 conversion or.....
