| Maker | The maker profile identifies Jan Kučera, lists Ostrava, Czechia, and describes a family of single-purpose desktop tools. | The site identifies Sergey Kazansky as the author and lists the Victoria Technical Center in Belarus, with a 2004–2026 copyright. |
| Purpose | DiskMaster monitors drive health on Windows, Linux and macOS. | Victoria diagnoses, tests and performs minor repairs on hard drives, SSDs, memory cards and other storage devices in Windows. |
| SMART monitoring | It reads SMART attributes, self-tests and drive self-test logs, using native ATA pass-through for SATA and USB drives. | Victoria analyzes SMART data and shows the status of each attribute for HDDs and SSDs. |
| Surface scans | Its read-only surface scan times blocks, confirms unreadable sectors with a second read, and maps them to sectors. | Its surface scanner checks for bad areas, unstable defects and interface errors, with automatic timeout and block-size adjustment. |

In their own words
DiskMaster
DiskMaster is a free desktop application for monitoring drive health on Windows, Linux, and macOS. It reads SMART attributes, self-tests, and test logs, then calculates a health score out of 100 and shows which attributes account for deductions; performance has a separate score. It stores readings in SQLite and charts changes, with alerts for shifts such as increasing drive counters. A read-only surface scan times blocks, rereads unreadable sectors for confirmation, and maps them to sectors. DiskMaster can identify files associated with those sectors and try to rescue copies while skipping unreadable bytes. Optional repair tools include sector and filesystem repair, zero-fill, and sanitizing bad sectors the filesystem marks as free. Alerts can go to Slack, Discord, ntfy, email, desktop notifications, commands, or JSON webhooks. Its CLI exports text, HTML, JSON, and CSV reports. SATA and USB monitoring needs no third-party tools; NVMe health logs and macOS use optional smartmontools. Raw SMART access requires administrator or sudo privileges.
Victoria HDD/SSD
Victoria HDD/SSD is a free Windows utility for diagnosing, testing, and making minor repairs to hard drives, SSDs, memory cards, and other storage devices. Its surface scanner checks bad areas, unstable defects, and interface errors, with automatic timeout and block-size adjustment. SMART tools analyze attribute status, read and write internal logs, and show built-in test results. A drive passport lists manufacturer, model, serial number, firmware, logical parameters, and interface details. The program retrieves identity and SMART data over USB, with the maker claiming support for 90% of USB-to-SATA bridge models. A quick test plots 188 points in about three minutes for any capacity but does not locate defects. Listed interfaces include M.2/U.2 NVMe and SAS/SCSI. PIO mode accesses IDE/SATA drives outside Windows and is intended for professionals with special knowledge. Victoria can erase media at the device's supported maximum speed. Windows 2000, XP, 7, 8, and 10 are listed, with at least 1 GB RAM and administrator rights required.
