ATA Attributes are reported as FAIL: NOW if VALUE <= THRESH since the early days of smartmontools (2002). The same applies to FAIL: PAST if WORST <= THRESH.

This is possibly because the original SMART specs did not specify whether <= or < should be used. The official ATA specs never defined SMART attributes and declared SMART READ DATA as obsolete in ACS-4 (2017).

Some recent drives return 255 for all three values which results in a bogus FAIL: NOW status (see ticket #1396):

Device Model:     Seagate IronWolfPro ZA3840NX10001-2ZH104
...
ID# ATTRIBUTE_NAME          FLAGS    VALUE WORST THRESH FAIL RAW_VALUE
...
246 Unknown_Attribute       PO----   255   255   255    NOW  0
...
                            |______ P prefailure warning

Comparison should be changed to VALUE < THRESH to better handle such corner cases.

As above. Brand new SSD's populated in a Synology NAS all report failure on attribute 246 "Unknown_Attribute".

Synology NAS can't use the drives as they report total fail.

Attached -x report.

This is a smartctl -x dump from a 14tb Western Digital drive.

A previous ticket was a dump from the bare drive, as connected via motherboard SATA.

I don't know if they're different or not, but figured your database folks would be able to tell.
