Mac Mini M2 - Sonoma - Disk Management Error 53249 - Problems Using & Mounting My SeaGate Desktop Drives (ExFat Formatted)

Hi all,

I am having errors connecting both of my SeaGate Desktop Drives to my Mac Mini M2 Sonoma OS.

Mac Mini M2
Sonoma OS
Disk Management Error 53249
Problems Using & Mounting both of My SeaGate Desktop Drives
Both Drives are ExFat Formatted
Both Drives are being Recognized by My Mac Mini M2 Sonoma
I tried running Disk Utility, First Aid, Mounting with no luck on either drive.
I also watched endless Youtube tutorials, but nothing is working.

Any Solutions Apple or Apple Community?

This is driving me wild with my brand new Mac Mini M2.

Thanks!

Mac mini, macOS 14.0

Drive's own power supply? Connected directly to the Mac? Formatted on the Mac as exFAT (MBR)?

If you're continually getting First Aid failures, you need to consider a drive is damaged regardless of age.

That being said, try a different format ... any format just to test. Failure there will also support drive failure.

If a drive is five years or older it should be replaced. but again, age is not the only reason drives fail.

Hi again,

So I tried just about everything.

I downgraded successfully to Ventura. - But I got the same error.
I bought a new powerful power strip. - But that didn't work.
Both SeaGate 8TB drives are formatted to exFat.
The First Aid on both drives didn't work.
The Mount on both drives didn't work.

But both drives are appearing in Disk Utility. Their names are lightly transparent, meaning something is not working. I provided a few more screenshots with details of my First Aid run and Disk Utility views.

On the screenshots I noticed "Owners Disabled", "Bootable No", "Writeable No", but I have no idea what those are.

Hey,

I'm also getting the same error with 2 of my WD 8 TB Mybook drive. Previously, both were formatted in exFat on Windows but as one was empty so I formatted again on Mac and it worked but now I'm finding a way to make the other work. As I have a lot of that on it. So, its bit difficult to format. Any Help????
