DiskMaster vs DRevitalize

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.

DRevitalize is Windows software for diagnosing and attempting to repair physical damage on magnetic media, including hard drives and some floppy drives. It works around damaged areas by generating sequences of high and low signals intended to repair bad sectors. The listed current version is 4.10 for Windows and UEFI, and public demo downloads are available for Windows, UEFI, and DOS. Modes include scan-only checks and scan-and-repair read or write tests. Other functions include SMART analysis, raw-data copying, secure erase, Format Unit, ATA security operations, and Device Configuration Overlay controls. The software is intended for minor surface damage, typically a few bad sectors, rather than hundreds or thousands. It can inspect and modify SSD parameters, but cannot truly repair a defective SSD sector; it may reallocate that sector. UEFI use requires a 64-bit system and recent BIOS. Windows support information says the product is designed for Windows 10, while version 4.0 requires at least Windows Vista and .NET Framework 4.6. License ordering is no longer available and the project is on hold.
