Some attributes are best viewed in hexadecimal format. To this end there is a "hex48" (48-bit hex) switch in smartctl, eg ... $ smartctl -v 5,hex48 -v 196,hex48 -v 203,hex48 -v 200,Write_Error_Rate - v 240,Transfer_Error_Rate -A /dev/ice You can also change the names of the attributes, as in the previous example. This article explains the attributes: http://en.wikipedia.org/wiki/S.M.A.R.T. I believe there may also be a switch to display smartctl results in "Fujitsu format". Here are three attributes that look better in hex: Reallocated_Sector_Ct = 9019431321600 = 0x083400000000 Reallocated_Event_Count = 826015744 = 0x0000313c0000 Run_Out_Cancel = 3728044065286 = 0x036400be0206 AIUI, the Reallocated_Sector_Ct consists of three 16-bit words as follows: (#spare sectors remaining) (#reallocated sectors) (#reallocation events) So, AISI, the drive has 2100 (=0x0834) spares with no reallocations. I believe the lower 16 bits of the Reallocated_Event_Count store the number of reallocation events. I have no idea what the Run_Out_Cancel data mean, except to say that the raw value appears to consist of three 16-bit words. As for the Raw_Read_Error_Rate, Seek_Error_Rate, and Write_Error_Rate (attribute 200), I understand the raw numbers to be a sector count, not an error count. Fujitsu (and Seagate) drives compute the error rates for each block of sectors accessed. Seagate appears to count up to 250 million sectors before the number rolls over to zero, whereas Fujitsu appears to count up to a much smaller number, probably 0x3FFFF (= 262,143). In short, I don't see anything that would worry me.
