Mac Doesn T Recognize Wd External Hard Drive

Hi Everyone. Suddenly, my MAC mini doesn't recognize my external hard drive any more. It was fine for years and today it's not 'there'.
I tried connecting with different fire wire cables and still, same problem.
I also tried connecting the external HD to my iMac and still, doesn't recognize it.
I tried restarting many times, still, same problem.
I tried disconnecting all cables and power cords, reconnecting them and powering on, and that didn't resolve it.
I have been searching the web all morning for ideas and can't seem to find a solution.
The external HD is a Maxtor III 300 GB. Older one but was big enough for my needs.
I was reading that sometimes doing a software update might cause an issue with external HDs. I just don't know how to resolve that if it is.
This hard drive is formatted for the Mac.
According to Maxtor I do not need to update my drivers. I was thinking that maybe one got lost.
Any help is appreciated. Thanks in advance!

If your drive is powered on but still isn't appearing in File Explorer, it's time to do some digging. Open the Start menu and type 'disk management,' and press Enter when the Create and Format Hard. Make sure that your external drive doesn’t become damaged in the future by always unmounting the disk properly after using it. Don’t just unplug the USB cable. To unmount your drive you can.
