Warranty for other drives after installing a SSD?

I added one more SDD on my laptop "last year"

and "recently", my HDD was failed (not recognized)

I chatted with the Dell customer center and they said that it is not covered within the warranty because I add one more "OTHER" SSD.

I never touched the HDD or changed the driver.

I just add one more new SSD on the laptop.

Is this correct??

If someone adds a new driver, the customer cannot get any warranty about even other drivers?
