Question about exos 7e8 warranty

Hello,

is there a way i can check how long is the warranty left on 2 exos 7E8 ST4000NM0265-2DC107 drives with dell pn ?

I have the PPID code

(also slight different question. the 2 drives have 0 hours of operation, and have been just initialized. is it normal that one of them , in the smart , shows

Hardware ECC recovered     1    1     0 , while the other shows  100   100   0  ( current  worst  threshold )

?)

Thanks in advance, Alessandro
