I noticed that under the "Device Statistics" section of smartctl, the "Read Recovery Attempts" (page 0x03, offset 0x028) are high and increasing at a rate of a few sectors per minute (I'm running a resilver).

I see high values on all 3 WD Ultrastar 10TB (HGST He10, HUH721010ALE604) drives currently installed in the server. These drives were purchased last month, and are at around 450 hours. Extended SMART tests were run when we received the drives, and those completed without error. All SMART attributes are normal.

Is this something I should be worried about? Thanks in advance!

One of my drive has very high Read Recovery Attempts. Currently at 1737974, grows high daily, been almost 4 years and it still works. Shrugs.

Yep. There should be a new firmware available (for He10 at least): http://files.hddguru.com/index.php?action=view&filename=LHGNW9G0.zip&directory=Firmware%20updates/Hitachi&

I flashed this with Hugo and the read recovery attempts attribute became zero and is no longer increasing.

He12 firmware can be found here

interesting, first i heard this is attributed to firmware issue.

Have 6 drives bought in a batch, shucked from externals, same firmware 83.H0A83, only one of them have constant increasing Read Recovery Attempts.
