Use Different USB Ports or Computers
If your Seagate 4TB external HDD is not being recognized by your computer, try using different USB ports or connecting it to another computer to see if the issue is with the connection.

Format to Compatible File System
To fix the issue of your Seagate 4TB External HDD not being recognized, one potential solution is to ensure that the file system format of the drive is compatible with your operating system. If the file system is not compatible, the drive may not be recognized by your computer.
First, check the current file system format of your Seagate external HDD. You can do this by connecting the drive to your computer and checking the properties of the drive.
If the file system is not compatible with your operating system, you will need to reformat the drive to a compatible file system. This process will erase all data on the drive, so make sure to back up any important files before proceeding.
To reformat the Seagate external HDD, right-click on the drive in File Explorer, select Format, choose a compatible file system such as NTFS for Windows or exFAT for cross-platform compatibility, and follow the on-screen instructions to complete the formatting process.
Once the drive is reformatted to a compatible file system, disconnect and reconnect it to your computer to see if it is now recognized. This simple fix may resolve the issue of your Seagate 4TB External HDD not being recognized.
