Empty total-lbas-written and total-lbas-read values for a SAMSUNG MZHPV128H
LS,
gnome-disk-utility reports no values (n/a
) for SMART attributes 241 (total-lbas-written
) and 242 (total-lbas-read
) for a SAMSUNG MZHPV128H AHCI SSD drive.
The skdump
utility (which also uses libatasmart) reports the right raw and pretty values (see below).
This is important because the drive reports FAILED status for attribute 173, which should be reported as Wear Leveling Count
but is not labeled (just as attribute-173
), seemlingly due to a Samsung firmware issue. See the ticket with patch I created for smartmontools: https://www.smartmontools.org/ticket/1113.
Another small issue is that the total-lbas-written
and total-lbas-read
properties are not localized (in Dutch).
