External Hard Drive Not Being Detected
The external hard drive itself, under normal circumstances, should be detected by your operating system, without the need of drivers, software or firmware updates.
But sometimes when you plug in any external hard drive to your PC (sometime a Segate), it may not show up or be detected by your PC. Consequently, the disk itself and the folders and files saved on it become unapproachable and unluckily this is a common problem with Seagate drives.
Usually, you can access the external hard drive through Windows File Explorer. However, there is a great possibility that the hard drive doesn't show up in the devices and drives list. Apart from that, the external hard drive might also not show up in Disk Management. The problem can be caused by one of the following reasons:
Broken USB port or broken USB cable
Unsupported File System
Partition issues on the hard drive
The hard drive driver is corrupted or outdated.
