[halimzhz]

Dear Sir,

For your information i did test with smartctl --test=long /dev/sda to the new WD1004FBYZ but not only 1 hard disk, i did test 4 hard disk and the result are same, too many numbers found on Unknown Attributes from the report of smartctl -a /dev/sda and i did test with smartctl ver 5.x and also 6.x and the result are same, please see the attachment, even the life time make me so worry, i repeat, i test with 4 hard disk for the same model and the Unknown attributes are keep increase for every minutes and hours

Please help. TQ

PLEASE do not use screenshots. Please provide full smartctl -x ... output as a plain text attachment. Then we could add or update the drive database entry for this drive. See the FAQ for further info.

Regarding your support question: RAW values are vendor and device specific. A large RAW value does not necessarily indicate disk problems. This specific value is possibly a Head_Flying timer or a Total_LBAs_Written counter.

This is a bug tracker, not a support forum. For future support questions, please use the smartmontools-support mailing list instead.

Thanks. The unknown vendor specific RAW value is likely a LBA read counter. It is similar to the related (vendor independent) Device Statistics value:

ID# ATTRIBUTE_NAME          FLAGS    VALUE WORST THRESH FAIL RAW_VALUE
...
 16 Unknown_Attribute       -O---K   000   200   000    -    14476
...
Device Statistics (GP Log 0x04)
Page  Offset Size        Value Flags Description
...
0x01  0x028  6           14476  -D-  Logical Sectors Read

This should be added to the existing drivedb entry for this drive. Leaving this ticket open until then.

Dear Sir,

Thanks for responce, this is my first time reporting the issue of the hard disk with smartmontools and i would like to know:

1- Should i ignore the lifetimes hours from smartctl -x report ?
2- The Smartmontools will update the smartctl and by that the OS i'm using now is Centos 6 and 7 will have update very soon ?

TQ so much

Re 1: Monitoring usage attributes like Power_On_Hours are useful if you want to proactively replace drives after some usage level has exceeded.

Re 2: We do not provide any smartmontools package for the various Linux distributions. Please contact the package maintainer or request an update in the bug tracker of the distribution.

Daily builds are available here: ​http://builds.smartmontools.org/
