Hi all, it sounds like I may have a similar problem.
Not really similar. Yours is apparently a hardware issue while that of the author seems to be software related.
I was using an external 6TB SanDisk G-Drive with my MacBook Air M2 2022. Everything was working fine until I upgraded to macOS Tahoe. After the update the drive won't mount but is visible via Disk Utility. Apple support reinstalled Tahoe which didnt solve it and deduced it was a faulty drive. Contacted Western Digital and just via web chat they have decided the drive is faulty after trying different cables and also on an older MacBook running Sequoia which also can no longer mount the drive. Any suggestions for a relative novice to these types of problems?
Your troubleshooting is working.
Power cycle the computer and the devices - usually a first step.
Always check cables and connections.
You've contacted the mfg and got their response.
You can erase and reformat the drive, then run diagnostic app and/or first aid routines on it and see if that resolves the issue.
You can replace the drive, esp if it's a five or more years old HDD.
It's very often that drive intensive operations such as OS installs can reveal weakness of older devices. Very coincidental and very often a process such as this is improperly blamed for such device failure.
Tip - it's always best to start your own thread when having a problem and asking for assistance. That way your issue will get the greatest focused attention and responses won't become background noise to the original author.
