SMART attribute differences between Windows and Linux

Intel SSD S3500

SMART attributes are different on Windows and Linux.

Notable, '175'

Linux:

175 Program_Fail_Count_Chip 0x0033 100 100 010 Pre-fail Always - 4295033464

Windows:

175 Power_Loss_Cap_Test 0x0033 100 100 --- Pre-fail Always - 623 (1 53)

In fact 175 is a bit field containing

Last test result (microseconds)
Minutes since last test
Total number of tests

which is returned by the Intel SSD toolbox

The drivedb.h versions on these two systems differ. The entry for S3500 was added in r3848.

On the Windows system the model family is known:

smartctl 6.2 2013-07-26 r3841 [i686-w64-mingw32-win7(64)-sp1] (sf-6.2-1)
...
Model Family:     Intel DC S3500 Series SSDs
Device Model:     INTEL SSDSC2BB080G4
...
Device is:        In smartctl database [for details use: -P show]
...
75 Power_Loss_Cap_Test     0x0033   100   100   ---    Pre-fail  Always       -       623 (1 53)

On the Linux system it is unknown. The default attribute interpretation is used:

smartctl 6.2 2013-07-26 r3841 [i686-linux-3.2.0-59-generic-pae] (local build)
...
Device Model:     INTEL SSDSC2BB080G4
...
Device is:        Not in smartctl database [for details use: -P showall]
...
175 Program_Fail_Count_Chip 0x0033   100   100   010    Pre-fail  Always       -       4295033464
