What is BLOCK SID

Block SID is a feature present in some TCG drives which, if enabled, blocks any attempt to change the authentication key. If Block SID is enabled, Opal Lock is not able to set up a password for the drive. Therefore, Block SID needs to be disabled before the drive can be set up using Opal Lock. Block SID can be disabled in the BIOS on startup before the Block SID command is executed.
