Tired of Acronis, EaseUS, and Partition Magic charging you $50/year for basic disk operations? So were we. Setec Partition Wizard is a comprehensive C++17/Qt6 disk utility covering partition management, formatting, recovery, imaging, diagnostics, security, and maintenance — all in one tool, completely free.

Features

Partition Management

Create, delete, resize, move, merge, and split partitions with a visual disk map
Full MBR, GPT, and Apple Partition Map support
GParted-style operation queue — preview all changes before applying them
Partition alignment optimization for SSDs and 4K sector drives
Raw partition table editing for advanced users

Formatting — Every Filesystem You Can Think Of

Modern: NTFS, FAT32/16/12, exFAT, ReFS
Linux: ext2/3/4, Btrfs, XFS, JFS, ReiserFS, Linux swap
Apple: HFS+, APFS (read-only detection), HFS Classic
Legacy & Retro: HPFS (OS/2), Minix, Amiga Fast File System, BeOS BFS, QNX4, UFS (BSD), Xenix, Coherent, SysV, ADFS (Acorn), UDF, ISO9660
Special: RomFS, CramFS, SquashFS, VFAT, UMSDOS

Yes, we support filesystems from the 1980s. Because why not.

Recovery

Deleted partition recovery — scans for lost MBR/GPT partition entries
File carving — recovers files by signature from MFT records, FAT directories, ext inodes, and raw byte-pattern carving
Boot repair — rebuilds MBR boot code, fixes Windows BCD, restores GPT backup headers
Supports recovery across MBR, GPT, and ext superblock structures

Disk Imaging

Full disk imaging — create and restore complete disk/partition images
ISO flashing — write ISO/IMG files to USB drives and SD cards with hybrid ISO and UEFI boot detection
Disk cloning — sector-by-sector or smart clone (skips unallocated space)
Checksum verification — SHA-256, MD5, and CRC32 on all imaging operations

S.M.A.R.T. & Diagnostics

S.M.A.R.T. monitoring for both ATA and NVMe drives — read all attributes, thresholds, and health status
Disk benchmarks — sequential and random read/write, queue depth 1 and 32
Surface scan — find bad sectors before they eat your data

Security

FIDO2/WebAuthn — enumerate connected security keys, manage PINs, factory reset, create/verify credentials via the Windows WebAuthn API
Encrypted vaults — create AES-256 encrypted virtual disk containers (XTS, CBC, and GCM modes) with PBKDF2 key derivation
Boot authentication keys — create USB-based HMAC-SHA256 tokens for application access control
All cryptography uses Windows CNG (BCrypt) — zero external dependencies, no OpenSSL

Maintenance

Secure erase — multiple wipe standards:
- Single-pass zero fill
- DoD 5220.22-M (3-pass and 7-pass variants)
- Gutmann 35-pass method
- Random fill and custom byte patterns
Boot repair with MBR reconstruction and BCD rebuilding

Screenshots

Coming soon — the UI features a tabbed interface with visual disk maps, operation queues, and real-time progress tracking.

Design Decisions

No exceptions — monadic Result<T> error handling throughout
No OpenSSL — all crypto via Windows BCrypt (CNG API)
RAII everything — disk handles auto-close on destruction
Operation queue — changes are queued, previewed, then applied atomically
Removable-only safety — ISO flasher refuses to write to fixed disks
Admin required — raw disk I/O requires elevation; app checks and prompts

A Note for the Curious

"Don't forget to look UP UP at space."

Some say if you press F5 while the application is running, something unexpected happens. Something involving a riddle about nothing, a dark void, and a very particular file that only your build can produce.

Those who grew up cleaning floors on the SCS Deepship 86 might feel right at home. The janitor always did have a knack for finding hidden things.
