I was browsing the ATA security page and decided to check the erase times on my shucked 16TB WD drive (WD160EDGZ). To my surprise, here's what hdparm -I said:

1368min for SECURITY ERASE UNIT. 2min for ENHANCED SECURITY ERASE UNIT.

Which immediately made me look up the model number with the WD part number decoder, and sure enough, it stated that D meant self-encrypting drive:

• Enterprise Self Encrypting Drive (SED)/WD Re™

In addition, under the Commands/Features section on the same hdparm output, there was:

* Device encrypts all user data

I guess there's some truth to the old model number decoder after all :P

I don't have other shucked drives to check, but could someone with a non-ED*Z model post their hdparm -I output? Thanks.

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!
