MacBook Pro M3 - Unable to create new folders on Seagate external HDD since macOS Sequoia 15.1.1 installed

Unable to create new folders on Seagate HDD since updating operating system to macOS Sequoia 15.1.1. No other changes have been made to the Seagate HDD itself. Previously I had no problems creating folders for the external HDD. Can anyone help?

MacBook Pro 14″, macOS 15.1

Formatted how?

Was it erased, reformatted,initialized before use to remove any proprietary software?


Look for some update to third party supporting app if formatted NTFS


Look for some update from Seagate for your model?


Try a different enclosure

different cable

different port


no resolve try a different external drive and compare your results.
