smartctl -A Missing Attributes

  • 772

I'm reviewing SMART attribute data for different disks and notice that some disks report the following attributes while other disks don't:

  • 241 0xF1 Total LBAs Written
  • 242 0xF2 Total LBAs Read

What determines whether this attribute is available for a given drive, and is there a way to tell this by looking at smartctl or hdparm output?

hard-drive

    The hard drive manufacturer decides what SMART attributes they will expose to you. If they decide not to track or give you that information, you can't really get it.

    As for how you determine what attributes are available, you look at the smartctl output, just as you already did.
