Hello,

Is it possible for "smartctl -i" to always print sector sizes? I got a new drive recently and wanted to find out its sector size. Smartctl wouldn't say, but then I accidentally found out (while reading its sources) that it actually prints that info, but only when the sector size is not 512. I think it would be much more intuitive if it always printed that, because the current behavior is a bit confusing (at least it was to me).

Thanks

If a problem is detected the first time, smartd sends only one warning email and possibly later optional (e.g. -M daily) reminder emails if the problem persists or reappears.

If the problem is no longer detected this state should be reset such that another email is always sent immediately when the problem is detected again:

-C ID -U ID: Reset if number of pending or uncorrectable sectors drops to 0. This typically happens when all known bad sectors have been reallocated.

-l selftest: Reset if number of failed self-tests drops to 0. Since r3272 this happens when an extended self-test is run after all bad sectors have been reallocated.

-W DIFF,INFO,CRIT: Reset if temperature drops below CRIT minus some reasonable threshold. For example below INFO if set or else below CRIT-DIFF+1 if set or else below CRIT-3.

The Intel 320 SSD series introduces a bunch of new SMART attribute IDs, as well as uses some existing one which smartmontools labels incorrectly. Let's try to fix those up by referring to Intel's own documentation as well as using the Intel SSD Toolbox software on a Windows machine.

Example from Win32:

smartctl 5.41 2011-04-19 r3317 [i686-w64-mingw32-xp-sp3] (cf-win32-20110419)

Attribute 170 (0xaa) = Available_Reservd_Space Attribute 171 (0xab) = Program_Fail_Count Attribute 172 (0xac) = Erase_Fail_Count Attribute 173 (0xc0) = Unsafe_Shutdown_Count Attribute 225 (0xe1) = Host_Writes Attribute 232 (0xe8) = Available_Reservd_Space Attribute 233 (0xe9) = Media_Wearout_Indicator Attribute 241 (0xf1) = Host_Writes Attribute 242 (0xf2) = Host_Reads

Attributes 170 and 232 are the same. I imagine they're used in combination to hold a vendor-encoded piece of data, but since my attribute values are 0, I can't help decode them.

Attributes 225 and 241 are the same. Intel SSD Toolbox shows "19.72GB" for the values of both Attributes 225 and for Attribute 241. So, somehow they're able to calculate the actual gigabytes used from one (or two) numbers of 632. I'm not sure if 19.72GB is calculated by using a unit base of 1024 or 1000, but there must be a way to calculate this. I will be more than happy to reach out to Intel to find out how to decode these values if requested; shouldn't be much of a problem.

Attribute 242 in the Intel SSD Toolbox shows "22.63GB".

Finally, I should note that the following attributes are NOT shown at all in the Intel SSD Toolbox, which may mean their values are used to assist or help calculate other attribute values which are shown.

Attribute 226 Attribute 227 Attribute 228

I will be more than happy to help test, or write code, to make all of this work. Please let me know, as I'm quite familiar with SMART attributes as can be indicated from my FreeBSD atacontrol patches that provide SMART capability natively:
