In their own words
DriveDx
DriveDx monitors and diagnoses SSD and HDD health on macOS, with the aim of helping users identify drive trouble before data loss or downtime. It evaluates indicators such as SSD wear and write endurance, I/O errors, pending sectors, and reallocated bad sectors. Its reports distinguish Warning, Failing (Pre-fail), and Failed states. The app can run in the background, check drives periodically, and alert users when it detects an issue. Users can initiate and control self-tests of electrical or mechanical performance and read performance. DriveDx calculates health and performance ratings, plus an indicator of remaining SSD lifetime. It can email problem alerts and drive status reports, with reporting configurable by criteria, and can alert users when free space crosses a chosen threshold. The product page lists compatibility from macOS 10.9 through macOS 26 and invites users to try it free, without specifying a trial length. There is no free plan. The personal license costs $19.99 as a one-time purchase for up to three personal computers and non-commercial use; other licenses cover household or commercial computer counts.
HDAT2
HDAT2 is a drive-testing and diagnostic program for ATA, ATAPI, SATA, NVMe, SSD, and SCSI/USB devices. Its device-level tools test drives and can repair bad sectors on detected devices. File-system testing covers MBR/GPT, boot data, and directories on FAT12/16/32, exFAT, and NTFS. SMART functions are available for ATA/SATA, SCSI, and NVMe drives. Capacity controls include SET MAX and Device Configuration Overlay, with options to restore full capacity; supported SATA and NVMe devices can also be switched between 512e logical sectors and 4Kn. HDAT2 detects devices on AHCI and some RAID controllers, and USB devices through USB ASPI or BIOS when supported. The main program requires a real DOS system booted from USB, floppy disk, or CD/DVD. A Windows 32/64-bit demo is available, but it operates only at drive level, omits file-level functions, and aborts almost all commands while simulating conflicts. The freeware plan is free, for one or more machines, with redistribution without profit; it is provided as-is without warranty.
