Smartctl - a note to myself

2nd September 2010
A note to my future self as I never seem to remember these smartctl commands (partly and fortunately because I don't need them often):
1. Quick check
/usr/sbin/smartctl -q errorsonly -H -l selftest -l error /dev/sdX
2. Run some tests if the command above reported any errors:
smartctl -t short /dev/sdX && smartctl -l selftest /dev/sdX

hdsentinel - or let's make smartctl reports readable

28th November 2010
I am sure lots of you have had problems in the past or simple annoyances because of the way smartctl reports stuff. Although sometimes it's good to have more information, when it comes to routine hard drive check less is more. And this is where hdsentinel comes in handy - it takes the reports from smartctl and makes it "human readable" it directly queries the HDD for S.M.A.R.T. data and displays it in a nice human readable format.
Here's how a hdsentinel report looks like (the red lines are my doing):
HDD Device  1: /dev/sdb
HDD Model ID : ST3250410AS
HDD Serial No: 9RY3E558
HDD Revision : 4.AAA
HDD Size     : 238475 MB
Interface    : S-ATA II
Temperature  : 41 °C
Health       : 30 %
Performance  : 100 %
Power on time: 603 days, 9 hours
Est. lifetime: 109 days
You can get even more information nicely formatted by using the -r switch (report).
And here's how a normal smartctl report looks like:

I think hdsentinel is well worth giving a shot, if only for the time it will save you in the data centre when doing batch checks.

Read more about the linux version here.
Download from here (just download, gunzip and run as root - yeah, it's not open source, but oh well...).
There are also versions for Windows Server if you're interested in such alternatives.
