Crystal Disk Info & S.M.A.R.T. interpretation question

sonicwind · 22 Sep 2018

I have a 1 TB data drive (already backed up) that shows a reallocated sector count (raw value) of 3348 in Crystal Disk Info in the main window of results.

If I hover over the yellow "Caution" under "Health Status," the notification popup says "Reallocated Sector Count: 13128"

So which is it? 3348 or 13128 reallocated sectors? And what is the other number?

You can see an example of the area I'm talking about at the top of the page here, except mine is yellow under Health Status and says Caution - https://crystalmark.info/en/software...l-information/

Thanks. I looked through the Crystal Disk Info online manual and saw no explanation.

Which ever you feel more comfortable with. They both refer to the same number

either way, it's a bad sign.

For the last few years we’ve used the following five SMART stats as a means of helping determine if a drive is going to fail.

Attribute		Description
SMART 5		Reallocated Sectors Count
SMART 187		Reported Uncorrectable Errors
SMART 188		Command Timeout
SMART 197		Current Pending Sector Count
SMART 198		Uncorrectable Sector Count

When the RAW value for one of these five attributes is greater than zero, we have a reason to investigate...

Indeed - especially if the number increases.

Apologies for the inappropriately placed smiley btw.
