Precautions Before Resetting Your Seagate External Hard Drive to Factory Settings

Your most burning question is probably: What happens when you factory reset a Seagate external hard drive?

You guessed it: you wipe all data. That's because you format the drive. However, it stays in the file system, leaving a chance of retrieval if you don't overwrite it with new data.

Still, creating a backup is the safest way to preserve your data. For instance, you can move it to another disk or use a third-party professional backup manager like Wondershare Ubackit.

Here's how straightforward it is:

1. Download and install Wondershare UBackit on your computer.
2. Connect your Seagate external disk to your PC.
3. Launch the program and navigate to Backup > Disk Backup.

   

4. Choose your Seagate external hard drive under External Drives and click Select.

   

5. Pick your backup destination and click Backup.

   

Wondershare UBackit works if you can access your Seagate external hard drive. If it's inaccessible, you'll need data recovery software (more on that in a bit).

💡 Pro Tip: 2026 Hardware Interface Alert (USB4 & NVMe Enclosures)
If you are connecting an older mechanical Seagate HDD through a modern USB4 port or an advanced multi-drive NVMe docking enclosure, firmware translation mismatches can sometimes mimic drive corruption or cause random write-protection blocks.
Before initiating a destructive factory reset, safely disconnect the drive, power cycle your host machine, and test the Seagate drive using a native USB-C or legacy USB 3.0 port. If the operating system still marks the device as unreadable, proceed with the system formatting options detailed below.
