Description Gioele Barabucci 2009-10-31 07:46:16 UTC
(I originally reported this as «https://bugzilla.gnome.org/show_bug.cgi?id=600219>)

Weird values are reported for the "Read error rate" SMART parameter for
my disk Seagate Momentus ST9250315AS with firmware revision 0001SDM1.

These values are

  value: "230874873" (raw 0xf9dec20d0000)
  normalized value "119"
  worst value is "100"
  threshold value is "6"

Could these values be sanitised somehow before reporting them?
Comment 1 Lennart Poettering 2009-10-31 08:06:09 UTC
What's wrong with that value?

Also, please attach the SMART data dump of your drive. You can generate it with 'skdump --save=foo /dev/sda'

> What's wrong with that value?

I, as a simple user with no knowledge of SMART, think that the read error rate cannot be 230874873 when the threshold value is 6 and the worst value 100.

Also if that huge value is real, why are both that parameter and the disk reported as OK?

Could the fact that I am on an amd64 system influence the reading or interpretation of that value?

Nah. That field has no well-known unit or decoding, we simply show the raw unit-less value there. It's not clear if smaller or bigger is better. There's nothing wrong here.
