Since macOS Big Sur, I have not been able open my external drive.
I have a lot of information on this hard drive and don't know how to get to it.
Can someone explain what has happened and how I can fix this?
I don't understand. Not very good with computers.

rhodes65, you external drive is formatted NTFS which is a windows based disk format. There are 3rd party applications that will allow you to read/write the NTFS format. Paragon software NTFS For Mac is one. You could download that and try it out to see it solves your problem. I noticed that you have a Seagate Branded drive. I would go to Seagate's site and see if they have an updated version of their software that will enable you to mount your external drive.
I hope this helps.
