Question software free test hdds

What's the best, 100% free software for analyzing the health of 2.5" HDDs? Is it necessary to have the HDD brand's software, or will another software provide the same results? I've used several: Victoria, gsmartcontrol, crystaldiskinfo, and HD Tune, but I wanted to simplify things by having only the best or the best free software.



I have 2.5" HDDs from HGST, WD, and Seagate, all of which are in a USB 3.0 case.



I access my HDDs once a week. Is it always necessary to repeat tests that take hours to prevent file loss and corruption?
 
CrystalDiskInfo, best free HDD health tools for me. If a drive is going bad, it’ll usually show up here first (Reallocated/Pending/Uncorrectable counts climbing).

Nope

Running multi-hour scans every week doesn’t prevent failure; it just adds wear (and wastes time). Drives usually fail predictably (SMART counters tick up, read errors show).
 
For three years, I performed a full surface scan with Seatools or HD Tune once a year, and the HDD was fine. I got this HDD from a friend, and his smart card was reset or firmware was replaced, but I performed the test after that.

From now on, is it necessary to perform a full surface test every year, or is just opening Crystal Disk Info and checking the SMART card sufficient?

Relying only on "drive is fast" tests (HD Tune benchmarks) won’t catch a sector quietly degrading.

Sufficient test:
  • Open CrystalDiskInfo weekly (or just set up alerts). If caution flag pops or counts start climbing, then you do a deep test.
  • SMART long test annually (if you want a sanity check).
  • Backups, because no software can predict sudden mechanical/electronics failure.
 
Among the various free software for scanning the surface of 2.5" HDDs, is there any difference in true accuracy in the tests, or do they all have the same accuracy and detail in the tests?

For SMART, I use crystaldiskinfo.
 
All free surface scan tools are equally accurate at finding bad sectors, the differences are in how much detail they give you. For SMART, CrystalDiskInfo is already perfect. If you want maximum visibility, pair CrystalDiskInfo with Victoria (for granular sector timing) and a vendor tool (SeaTools, WD Data Lifeguard, HGST WinDFT) if the drive starts to misbehave.
