File size: 111 MB

This HDD Low Level Format utility can erase and Low-Level Format a SATA, IDE, SAS, SCSI or SSD hard disk drive. Will also work with any USB and FIREWIRE external drive enclosures as well as SD, MMC, MemoryStick and CompactFlash media.

Common use cases
- Inspect a drive before reuse, fully wipe a USB SSD or flash drive, and confirm that a device is fully readable
- Prepare media for redeployment, run destructive wipe workflows with explicit logs, and export audit-friendly device details
- Collect raw device identity and health details, verify host-readable access, and understand exactly which Windows storage path is in use

What v5 adds
- Physical-drive inspection with Windows identity plus NVMe, ATA/SATA SMART, and USB SAT details where the current Windows path exposes them
- Read Verify: host-side full-device sequential raw reads with progress, elapsed time, ETA, and logging
- Low-Level Format: destructive whole-device zero-write path with explicit double-confirmation, stop support, and post-operation device refresh
- Trim: destructive whole-device discard / TRIM workflow, equivalent in intent to Linux blkdiscard
- Detailed operation logs, exportable inspection details, startup diagnostics

Operations
- Read Verify: read the whole physical device from the host side without writing to it
- Low-Level Format: write zero-filled buffers across the entire selected physical drive
- Trim: send full-device discard / TRIM requests; faster than full LLF but does not guarantee full data destruction
