hello, how to know that firmware is a hard disk, when it has the sticker on the driver and may not be known by software, as this burned, there is another way to find out? Thank you.

Your post is not clear, whether the hard drive itself is burned or just the sticker, and what software you used.
But I suggest to download tools from the manufacturers websites to detect hard drives information.

Good luck!

sorry for my English, my question is, how many and what are the ways to know what the firmware of the hard drive?

To clarify......you would like to know if the FW version applied to the drive is different to what is written on the drive label?

The easiest way, if you don't have access to specialist tools, would be to use the manufacturer specific application to determine which FW version your drive is running. For example, use SeaTools if you have a Seagate HDD.

that whenever the hard drive works, but if you burned the plate?

If the board is burned, you cannot get any information.

But what about the hard disk itself, is it also burned?

Take a screenshot and post it to see what is exactly the condition of the drive.
