:bulb: How to completely (unrecoverably) wipe an SSD on Windows 11 using Secure Erase.

Environment: Windows 11 + 2 SSDs (C: OS / H: target for deletion)

[01] Why Regular Formatting Isn’t Enough

Standard Windows formatting (quick or full) only removes the file system index — actual data remains on the disk.

Method Data actually removed? Recoverable?
Quick format X Yes, with recovery tools
Full format X Yes, with recovery tools
Secure Erase O Practically impossible

[02] What Is Secure Erase?

Secure Erase is an initialization performed by the SSD’s internal controller.

Trait Description
Scope Erases data on every cell
Recoverability Practically impossible
Speed 1–10 minutes (independent of capacity)
SSD performance Restored to factory-fresh state

[03] Frozen State — Why a Reboot Is Required

When Windows is running, the OS puts SSDs in a Frozen (security lock) state. Secure Erase cannot run in this state.

Windows running
  → SSD state: Frozen (security)
  → Secure Erase: cannot run

USB boot (pre-boot environment)
  → SSD state: Not Frozen
  → Secure Erase: can run

:warning: Secure Erase must be run in a pre-boot environment (before Windows starts).

Resolving Frozen state:

Environment Resolution
Laptop Enter Sleep mode → wake again
Desktop Re-seat SATA cable (rarely needed)
Common Boot from USB to enter pre-boot

[1] Create Secure Erase USB

[2] Reboot PC

[3] Boot from USB via BIOS
  ↓
[4] Run Secure Erase
  ↓
[5] Select target SSD (⚠ critical)
  ↓
[6] Done — SSD restored to factory state

[05] Method 1: Samsung Magician (Samsung SSDs)

5-1. Requirement

  • Using a Samsung SSD (860 EVO, 970 EVO, 980 PRO, etc.)

5-2. Procedure

1. Run Samsung Magician (as Administrator)
2. Left menu → Secure Erase
3. Create bootable USB (USB required)
4. Reboot → boot from USB
5. Select target SSD → execute

5-3. If USB Creation Fails

Common error from Samsung Magician:



1



"Failed to create bootable USB drive"

In that case, use Method 2 (Rufus).

[06] Method 2: Rufus + ISO (Recommended)

Use when Magician’s USB creation fails, or when you have a non-Samsung SSD.

6-1. Requirements

Item Description
USB 8GB+
Rufus Download from rufus.ie
ISO Samsung Secure Erase ISO or Parted Magic

6-2. Rufus USB Settings

Boot selection:   ISO file
Partition scheme: GPT (for UEFI)
File system:      FAT32

6-3. Boot from USB

1. Restart PC
2. Enter BIOS (F2, F12, DEL — varies by vendor)
3. Boot menu → select USB
4. Run Secure Erase tool from USB

6-4. Run Secure Erase

1. Identify target in the SSD list
2. Select the SSD to wipe
3. Execute Secure Erase
4. Complete in 1–10 minutes

[07] Avoiding Wrong SSD Selection

:warning: Selecting the OS-installed SSD will wipe your system. Triple-check the target.

Check Description
Capacity Compare sizes (C: vs H:)
Model name Check via Samsung Magician or BIOS
Disk number diskpart → list disk to see number + size

# Pre-check in Windows
diskpart
list disk

  Disk ###  Status         Size     Free
  --------  -------------  -------  -------
  Disk 0    Online          476 GB    0 B     ← C: drive (OS)
  Disk 1    Online          931 GB    0 B     ← H: drive (target)

Note capacity and disk number before running Secure Erase.

[08] Alternative: DiskPart clean all

When Secure Erase isn’t available, use the Windows command alternative.

diskpart
list disk
select disk 1          # target disk number
clean all              # overwrite entire area with zeros
Trait Description
Operation Overwrites entire area with zeros
Recoverability Very low
Time 1–3 hours per TB
Pros No USB boot needed, runs from Windows
Cons Slower than Secure Erase; no SSD performance restoration

[09] Method Comparison

Method Time Recoverability SSD performance restore Recommended
Secure Erase 1–10 min Practically impossible Yes ★★★★★
DiskPart clean all 1–3 hr Very low No ★★★
Regular format Seconds High No Not recommended

[10] Summary



1



SSD complete deletion = Secure Erase (NOT format)
Tier Task
1st Samsung Magician Secure Erase
Fallback Rufus + ISO USB boot
Alternative diskpart → clean all (slower but works from Windows)

:warning: Back up important data first. After Secure Erase, recovery is practically impossible.
