I have several Hitachi Ultrastar SSD400M Model #HUSML4040ASS601. They had a block size of 520 and I was able to successfully format all but one of them using sg_utils' sg_format to 512. However, one of the drives reports "sense key data protect".

Is a way to disable data protect on the drive?

  • Operating system? RAID controller? SAS controller? Server hardware? You're missing some details.

  • O/S is Centos 7, Controller is LSI 9211-8i, Server is HP DL385 G5.

The Sense Key Data Protect is received when the device locked, It might be either a physical write lock or encryption. Most probably it is encrypted and you will need the password(s). You may check HGST Support for how to reset or unlock the drive.
