You ran into a serious Bug, if you have legitly aquired this Block, please report it immidietly [sic] is a block that exists in versions 2-4. It is the block used to represent a GregTech TileEntity block that has lost the TileEntity data that would otherwise identify it. It is most commonly created after server-crashing TileEntity errors (such as ClassCastExceptions), and is used as an emergency fallback to prevent further world corruption.

除了服务器崩溃和所谓"严重Bug"，并无合法的手段"确定可以获得此方块".
