macbook pro 2021 error 119930874 mounting external HD

Hello, macbookpro from 2021 is being slow to mount external HD (Seagate backup plus drive 2TB), and got this error when I tried to mount it from Disc utilities:


error de com.apple.DiskManagement.disenter -119930874

It mounts after a few minutes, but I'm curious if this can be fixed.


Seagate has a USB-A and I'm using a USB A to USB-C adaptor (attached pic) to connect it to the Thunderbolt in the macbook pro.


Adaptor specs:

Version: 3.1 Gen 1

Connection 1: USB C male,

Connection 2: USB A female,

max. speed: 5 Gb/s.


Wondering if this is the problem and how could I fix it?

Cheers!

Hey there ely247,


Thanks for reaching out to the Apple Support Communities. For the best steps that can help with troubleshooting issues with your USB devices not working as expected, check out this link here: If a USB device doesn’t work with Mac - Apple Support


If still having issues after going through the steps above, try testing the issue in safe mode.


This can help to determine if the issue may be caused by some software that has loaded as your MacBook starts up. For help with booting into safe mode, and what to do if the issue does or doesn't occur in safe mode, check out this link here: How to use safe mode on your Mac - Apple Support
