Hey,

 

I just stumbled upon the S.M.A.R.T. data of one of my HDDs and I am starting to worry if it could fail soon.

It's a 8TB Seagate IronWolf NAS drive and the data that's worrying is the LBAs written and LBAs read aswell as Hardware ECC recovered. The drive is only 25 days old but way over what Seagate recommends. Seagate says on their site that this drive has a workload of 180TB/year.

 

My questions are:
Are the LBA datas wrong or should I worry? If so, how can I reduce the write and read?

Can hardware ECC recovered be corrected by using ECC ram? 

Am I voiding my warranty by reading and writing more than Seagate recommends?

 

I'm attaching my S.M.A.R.T. report data from DiskSpeed docker.

 

Thank you for your help

You can ignore that.

 

As for the total reads/writes they seems excessive, I suspect diskspeed is misinterpreting the SMART data, please post the SMART report using the GUI.

Yeah sure. 

 

Here is the S.M.A.R.T. report from the GUI. Let me know if you need anything else.

Like suspected it's showing the wrong values:

 

241 Total_LBAs_Written      ------   100   253   000    -    16039330064
242 Total_LBAs_Read         ------   100   253   000    -    33785959168

 

Logical sector size is 512 bytes, total LBAs written is the raw number x the logical sector size, so total writes are currently 8.2TB, diskspeed is multiplying by the physical sector size (4096 bytes), so you need to divide by 8 to get correct values.

Thank you very much. Makes total sense that LBA means the logical sector size but I wasnt quite sure. The usage now seems realistic.

 

 

Just going to ping @jbartlettso we can take a look at the calculations.

It is indeed multiplying the value by the Sector Size instead of the Logical Sector Size in error. I've made a correction for the next DiskSpeed update.
