"Disk not ejected properly" error - Sandisk Extreme 2TB

[1brajesh]

In addition to this problem, has anyone had a challenge ejecting the disk? Now it says "the disk wasn't ejected because one or more programs may be using it" when I have no other programs running - including a Time Machine backup!

This happens to almost all my external drives once in a while (not just the Sandisk).
I usually have to close the finder and re-open it. Or just wait a few minutes and try again.
If nothing works, I unmount using disk utility which usually does the job.

Common issue. Your programs might not be using it but a system process such as spotlight indexing might be active on that volume. There are terminal commands which can sometimes help in isolating processes using a specific drive.

Best to avoid drastic solutions if you can to avoid the possibility of data corruption.

Somehow look at the Foto from the TE:

Yellow Anker Cable from Power Supply ( Wattage ? ) to Hub
Fixed Cable to Hub from unknown origin
USB-C cable to Sandisk looks not Centered in Sandisk and is not ORIGINAL ( UNI not bad but what Specs ? )
What is the Second USB-C cable from the Macbook going to ? And as it is looking to being higher Specs than the UNI USB-C Cable did he try this ?
He tried USB-A on Hub for Sandisk but not USB-C on Macbook direct ?

How many USB connected Devices we have her and what for...........

A very well done unpredictable mess.

Just to explain, since it's not that I have been using Mac for the last couple of years only... I never had major issues with cables.

The issue was present with both the Anker yellow cable and the original white one that came with the Mac and its original power brick.

The SanDisk is connected with an UNI usb-3 cable.
Again I still have the original SanDisk cable: same exact issue.

The other three USB cables at the top are:
- a wired Logitech mouse from the early 2000s (don't ask) - it was just connected when I took the pic, otherwise not
- a Logitech Litra I was messing about. Cable is Logitech.
- an USB to lightning (red) cable, mostly unplugged. Cable is Anker.

I hate the USB dongles, and yes, I wouldn't consider that a stable setup.
I've had all sorts of issues with too many USB devices connected to and USB dongle.
The bad design starts with having the dongles, but I digress.


I'm now back home and at my desk I'm back using my new Mac Studio.
I have three external drives connected directly to the rear USB-C/Thunderbolt ports.
They all use proper USB-C/USB-C, USB-C/USB-A cables, USB3 rated.

One drive in an external SSD. Powered via the USB cable. Seems fine.

Second drive is an older LaCie D2 that I use as a TimeMachine disk. I has its own power brick and power source. It disconnects continuously while the computer is asleep or idling.

Third disc is an external QNAP enclosure with 4 drives in a RAID array. It has its own power brick and power source.
It disconnects continuously while the computer is asleep or idling.


When the discs disconnect, sometimes I get the error notification, some other times I just notice because the icons on the desk are all over the place.


Had the same exact drives connected to my previous desktop mac (Mac mini) for a few years and never had an issue.

We can try and keep changing cables as much as we want, but the issue here is the buggy AF OS.

Where is USB Restricted Mode controlled?​

• The protection is enabled by default on Apple Silicon Macs.
• The enabled protection is to Ask for new Accessories, additional options include:
  • Ask every time.
  • Automatically when unlocked.
  • Always.
• Asking for new accessories is the minimum protection that should be in place, though highly secure enterprises will want to mandate for permission each time.
• You can disable/enable the setting in System Settings>Security & Privacy>Security.
• Configuring an accessibility Switch Control sets the policy to always allow accessory use.
• Approved devices can connect to a locked Mac for up to three days.

Where exactly? I cannot find this in the same location as your screenshot.
Thanks!

This is only avail on Mobile Devices / Laptops.......

For the Sleep related Problem ( have no other ) i use Jettison now, this makes sure the drives are getting unmounted before sleep and remounted on wake, so no Data loss is possible.

5 Bucks good invested.

I've received my new T7 Shield 2TB and so far it's working fine (2 days).
I'm returning the Sandisk.

Thanks, didn't know it wasn't available on desktops.

I'll give it a go.
If a drive is being used (files left open, etc.), there should be no disconnecting issue, right?

If there is, you have probably a cable issue or the chipset of either the Drive, the USB Adapter / Hub or Enclosure has Problems.

Jettison only helps with the Sleep related Problems if anything else works.

Just here to confirm that it's NOT the cable. Interesting to hear from folks having both the 2TB and the 4TB ... and the 4TB does not have the same issues. I have other external SSD's I use on my MBP, and I can swap the cables and drives around willy-nilly. The ONLY drive that gives the random spurious dismount warning is the Sandisk Extreme 2TB.

It is always there when I try to use it. I've just been ignoring the warnings, but they are annoying. Video and 3d software accessing the drive seems just fine, despite the warning. The computer thinks the drive is there, and has no problem accessing it. But the messages keep coming.

It's the drive. In my experience, Sandisk has a horrible track record of blaming everything else .. had bad SD cards from them too ... and the only change was switching to a different card. It's not me, bad practices, my devices, cables, or my personal chaos bubble.

Thanks for sharing. Just to correct something which seems like a typo, it's not Samsung, it's Sandisk Extreme. Samsung works fine.

Yep. Coming back to this thread once again as I keep having disconnection issues both on the SanDisk originally discussed on this thread (connected directly to a MacBook Pro via the provided cable) and on a mechanical LaCie hard drive on a MacStudio (again connected directly to the Mac, proper cable).

On the Studio I have 2 other SSD connected that are a piece of crap built salvaged SSDs from my old mac mini, inserted into cheap external enclosures bought on Amazon and connected to a hub, then to the mac.
The hub is powered, so I think those SSDs are always on despite the Mac going to sleep/low power.
