i have, what appears to be an almost fully functional Seagate Elite9 FastSCSI 9GB HDD. (ST410800N)

It spins up, doesn't make "odd" sounds, doesn't smell of capacitor juice, and it recognized by my SCSI controller.

But, as you can see in the images, there are 2 destroyed (what i think to be, capacitors), but maybe some other passive electronic like an inductor or resistor.

I can't find the board schematics. Does anyone have one of these units and can help me figure out what those 2 components are?

Thank you!

These are not pair of capacitors, these are pair of inductors 8R2J which is 8.2 uH. Find them and replace them regardless of type as long as they are 8R2.

Wow! Sherlock? How do you know these are 8R2J inductors ?

Searched lot of photos online and f0und 2, one little blurry and one more clearest to confirm.

Capacitors do not have this inductor notation for value and one more thing, I worked with electronics for years, also is correct type of style of packaging indicates inductor also.
