[smartmontools-support] smartmon Tools line interpretation help

[Jorge Bozzarello]

Hello, I'm sorry to bother you, I'm using your tool and I get this result in the line "sector size", I do not know how to interpret it. If physical and logical are the same or there was no reading of physical sector, thank you.

smartctl 6.5 2016-05-07 r4318 [x86_64-w64-mingw32-2008r2] (sf-6.5-1)

...
Sector Size: 512 bytes logical/physical
...

The above sector size is reported if the corresponding field in IDENTIFY
data (word 106) is unset (0x0000) or valid (0x4000).

To check what the drive actually returns in IDENTIFY data, try:

# smartctl --identify=wn /dev/sda
...
106 0x4000 Physical sector size / logical sector size
...
