Internal cdrw/ dvd-rom- does firmware stay after formatting HDD

Am considering formatting my HDD and installing all software all over,
XP home, et al…

Need to clean gunk from my computer.

Question is:
“Will my internal Toshiba SD R2312 firmware be reset? Or will the current firmware which I put onto it (x905) stay there?”

When I reinstall my software recovery discs I am under the opinion that all devices will be reset to default settings.
Just checking…

Thanks,
Robert

Firmware updates (drive or motherboard) are never reversed by any form of restore or re-install.

Thanks. I feel better,
