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…


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

Thanks. I feel better,
