Why Is an External Hard Drive Not Showing Up on Mac [macOS 13/12/11]
On Mac, my external hard drive has abruptly vanished. My external storage disappeared when I updated my iMac Pro to Big Sur 11.6. Not even in disk utility. Other ports, cables, and a Macbook Air have all been attempted. Although I can see that it is turned on, it is just not visible in any form. Why does it happen?

Because the external hard drive is formatted in an unsupported format by macOS, such as NTFS, HFS+, or another, your external hard drive cannot be read on a Mac. Thus, the most frequent problem is improper drive formatting. You'll need to use Disk Utility to format your drive differently in this situation. Other causes could be a wrong power source, a defective cable, or a corrupted or damaged drive.
Another potential explanation for the external drive's failure to be detected by your Mac is a frayed or loosely attached USB cord. To resolve the problem, replace the cable. If your Mac cannot recognize the external hard drive, try carefully plugging it in. Older external drives with USB 2.0 ports have a design issue that necessitates a slow connection.
The file system issue is the most apparent cause of your external hard drive's detection but unable to be opened. If your industry is experiencing similar problems, you can use First-Aid to attempt a self-healing solution and regain access to your files.
