My experience with Seagate drives is that they tend to fail when the number of errors goes over 1000. Search This Blog Loading... The failure level is a 30 and it is currently over 60. Member Posts: 360 Re: Seagate with huge Seek Error Rate, RMA? « Reply #14 on: April 03, 2014, 01:55:57 AM » Wow, I did not know that.
There are no way to preclear and there are so many possible drives to fail. Based on the abovementioned Error Recovery Usage Rate formula, I now postulate that the normalised value of the Raw Read Error Rate attribute could be calculated as follows: normalised RRER = Recover We can Recover your Files, Just in Case.

I have found the smart information to be quite a good indicator of pre-fail.

In fact my Internet research tends to confirm a maximum of 120 for 7200.11 models, but the threshold figure is 6. What Is Raw Read Error Rate Logged vca Sr. Here are the smarts from my drives so you can compare (note the newer version of unRAID has an updated version of the smart tool that gives some better attribute names The formula also refers to sectors being transferred "ToOrFromHost" which doesn't make sense for a read attribute.

E.g. http://wx2me.com/error-rate/seagate-seek-error-rate.php You can also include a comment. When you get a smart threshold tripped then replace the drive. we get a result of 79.65 Note that we have used 1 instead of 0 for the error count (because log 0 is indeterminate).

When diagnosing a Seagate I tend to ignore those and look more closely at other fields like Reallocated Sector Count. http://wx2me.com/error-rate/seagate-3tb-seek-error-rate.php So with values that go up, like number of errors, 0 = 100 then as the errors go up the 100 normalized value should go down...
Personally, I consider a drive containing error log entries as "failing" and urge for a replacement as soon as they occur. Seagate Smart Values However, it also produces an inconsistent threshold value, which is why I have always felt uncomfortable with it. It has recorded 0x0580A6AC seeks (= 92 million) without error.
