[smartmontools-support] Likely SMART attributes for SQF-P10S2-8G-ET2

[Andreas M. <an...@us...>]

Hi,

I just found the following likely correlation for SQFlash SMART attributes:


. [231 DriveTemperature "Temperature_Celsius"]
. 232? SQEnduranceRemainLife? "Available_Reservd_Space" 100
. 233? SQPowerOnTime? "Media_Wearout_Indicator" 2021164 (clearly a value incrementing in seconds)
. 234? SQECCLog? "Unknown_Attribute" 0
. 235? SQGoodBlockRate? "Unknown_Attribute" 99
. [240 HeadFlyingHours "Head_Flying_Hours"]


(smartmontools ID strings as shown by a 6.1+svn3812-1 log).


judging from the following:

identifiers of *generic* attributes in smartmontools:

  case 225:
    if (ssd) return Unknown_SSD_Attribute;
    return "Load_Cycle_Count";
  case 226:
    if (ssd) return Unknown_SSD_Attribute;
    return "Load-in_Time";
  case 227:
    if (ssd) return Unknown_SSD_Attribute;
    return "Torq-amp_Count";
  case 228:
    return "Power-off_Retract_Count";
  case 230:
    // seen in IBM DTPA-353750
    if (ssd) return Unknown_SSD_Attribute;
    return "Head_Amplitude";
  case 231:
    return "Temperature_Celsius";
  case 232:
    // seen in Intel X25-E SSD
    return "Available_Reservd_Space";
  case 233:
    // seen in Intel X25-E SSD
    if (hdd) return Unknown_HDD_Attribute;
    return "Media_Wearout_Indicator";
  case 240:
    if (ssd) return Unknown_SSD_Attribute;
    return "Head_Flying_Hours";
  case 241:
    return "Total_LBAs_Written";
  case 242:
    return "Total_LBAs_Read";
  case 250:
    return "Read_Error_Retry_Rate";
  case 254:
    if (ssd) return Unknown_SSD_Attribute;
    return "Free_Fall_Sensor";
  default:



Partial section of a list of identifiers in SQFlash-SMART.exe:

LoadUnloadCycleCount
LoadInTime
TorqueAmplificationCount
PowerOffRetractCycle
GMRHeadAmplitude
DriveTemperature
SQEnduranceRemainLife
SQPowerOnTime
SQECCLog
SQGoodBlockRate
HeadFlyingHours
TransferErrorRateFujitsu
TotalLBAsWritten
TotalLBAsRead
ReadErrorRetryRate
FreeFallProtection


Since the relevant SQ* IDs are clearly surrounded
by the very narrow DriveTemperature (231) and HeadFlyingHours (240)
integer range, it's very obvious that the interim values must be SQ*,
quite likely in incrementing order, since all the other (not pasted) values
in the SQFlash-SMART.exe list do correspond to smartmontools values
in proper sort order, too.

BTW the non-advertised TransferErrorRateFujitsu identifier
is "interesting" since it sits it in the middle
between Head_Flying_Hours 240 and Total_LBAs_Written 241 - huh??


So, what to do? And any additional advice how to implement the new
identifiers? :)
