lrnselfreliance dac849f9f6 Surface coarse SMART health for USB-bridge drives (#498) ... * Surface coarse SMART health for USB-bridge drives USB enclosures that reject ATA pass-through (e.g. Seagate Expansion) are invisible to pySMART/DeviceList, so the drive shows no SMART at all on the Controller page. Fall back to smartctl over the SCSI transport, which many such bridges still answer, to report a coarse PASS/FAIL health plus drive identity (model/serial/capacity). The health (-d scsi -H) and identity (-d scsi -i) reads are issued as separate calls: combining them makes smartctl suppress the health line when the identity read reports "SMART support is: Unavailable" (which these bridges do). The entry is marked smart_limited (labelled "(limited)" in both UIs) so a green PASS is not mistaken for full monitoring — these drives expose no attributes or temperature, and some bridges report "OK" statically. * Harden SCSI health fallback (Greptile review) - _scsi_health: treat any unrecognised status (e.g. "UNKNOWN", "N/A") as unreadable (None) instead of a false FAIL. Only "OK" -> PASS and "FAIL*" -> FAIL; anything else omits the drive rather than showing a red FAIL that contradicts the smart_limited disclaimer. - get_all_smart_status: isolate the SCSI supplement loop in its own try/except so an error there cannot discard the pySMART results already collected. --------- Co-authored-by: Claude Opus 4.8 (1M context) <noreply@anthropic.com>		2026-06-26 09:05:06 -06:00
