Seagate Data Recovery
Recover files from Seagate external and internal drives that were deleted, formatted, or stopped mounting.
Written by the Refindo Recovery Team · Updated
Seagate drives turn up everywhere, from Backup Plus and Expansion externals to internal Barracuda and FireCuda disks, and they fail in the same ordinary ways any drive does: a delete, a format, a RAW error, a volume that stops mounting. As long as your computer still detects the drive, Refindo can scan its NTFS, exFAT, or APFS volumes, preview what comes back, and recover it to a separate destination. Refindo is independent software and isn't affiliated with Seagate.
What this covers
- For Seagate externals (Backup Plus, Expansion) and internal HDDs
- Deleted files, formatted volumes, RAW errors, and drives that won't mount
- Supports NTFS, exFAT, and APFS on Windows 10/11 and macOS 12+
- Quick Scan for intact file systems, Deep Scan for damaged ones
- Preview before you recover, and save to a different drive
Recovery Workflow
- Connect the drive directly with a good cable; use the power adapter on desktop models.
- Check Disk Management or Disk Utility for the drive at its correct capacity.
- Run Quick Scan first when the file system may still be intact.
- Use Deep Scan for formatted, RAW, or unreadable volumes.
- Preview what matters and recover it to another drive.
Best Practices
- Rule out cable and power before assuming the drive failed.
- Don't accept a format prompt on a drive that holds data you need.
- Recover to a separate disk, never back onto the Seagate drive.
- If it clicks, grinds, or beeps, stop and consider a hardware lab.
Power and cable come first on Seagate externals
Before treating a Seagate drive as failed, rule out the boring causes. Desktop models like the Backup Plus Hub and Expansion Desktop need their own power adapter, so a drive that won't spin up is often just unplugged power rather than a dead disk. Bus-powered portables depend on a single cable for both data and power, and a worn cable or an underpowered hub can drop the connection mid-read.
So connect the drive straight to a port on the computer with a cable you trust, give desktop units their adapter, and keep it steady while it reads. If it then shows up in Disk Management or Disk Utility at its real capacity, the hardware is alive and you're looking at a file system problem a scan can handle.
- Desktop Seagate drives need their power adapter, not just USB.
- A correct reported capacity means the hardware is reachable.
- A flaky cable or hub can look exactly like a failing drive.
Deleted, formatted, or RAW Seagate volumes
Once the drive is detected, the recovery itself is the standard process. Deleted files and a quick-formatted volume usually leave the data in place until something overwrites it, so a Quick Scan often returns files with their names and folders intact. A drive that shows as RAW or asks to be formatted has a damaged file system header, not erased data, and a Deep Scan reads past that to rebuild files from their content.
Whatever the case, recover to a different drive. Saving files back onto the Seagate drive you're scanning can overwrite the data you haven't pulled off yet.
- Quick Scan first for deletions and quick formats.
- Deep Scan for RAW, unreadable, or unmountable volumes.
- Always recover to a separate destination.
When It Is Hardware, Not Software
Know the line between a scan and a lab
Recovery software works when a Seagate drive is electrically healthy enough to be read, which covers deletions, formats, RAW volumes, and file systems that won't mount. It can't fix mechanical failure. Clicking, grinding, beeping, repeated disconnects, or a capacity that reads wrong all point to a physical fault, and every extra power cycle can make it worse. If you see those signs and the data is irreplaceable, stop and have the drive imaged by a hardware recovery lab.
Frequently Asked Questions
Can I recover data from a Seagate drive that won't mount?
Usually, if the drive still appears in Disk Management or Disk Utility with its correct capacity. A drive that is detected but won't mount is normally a file system problem, which is exactly what a scan handles. If it clicks or beeps, that's mechanical and a job for a lab.
My Seagate external drive asks to be formatted. What now?
Don't format it. That prompt usually means a damaged file system, not lost data. Cancel it, scan the drive, and recover what matters before you reformat it for reuse.
Do Seagate desktop drives need their power adapter?
Yes. Larger Seagate desktop models like the Backup Plus Hub and Expansion Desktop use their own power adapter, not just USB. A drive that won't spin up is often a power or cable issue, so rule that out before assuming the worst.
Is Refindo affiliated with Seagate?
No. Refindo is independent recovery software and is not affiliated with or endorsed by Seagate. It works with Seagate drives the same way it works with any drive the operating system can read.
