Unfortunately this is my work desktop machine, I don't think it has an
accelerometer in it... my personal laptop at home would appear to have
this line:
191 G-Sense_Error_Rate 0x000a 100 100 000 Old_age
Always - 0
Which according to google is something to do with shock-sensitive sensor
on the drive.
Unfortunately I'm not an expert in analysing the output to tell you what
the numbers mean, I expect there is some software that will do a better
analysis job but I don't know of any off-hand. I've only used it once
before in anger on a drive that was making odd noises and behaving
strangely, one of the numbers was huge, which I looked up and google
suggested it indicated a failing drive, so I backed up the data and
replaced it :)
