Samsung not installed under bios

hey guys:D

I forgot what type of samsung it is, but its from on my 05 dell… :eek:
it used to work fine then the cdrw icon vanished…:sad:
i deleted lower filter’s and now it just looks like a hard drive icon (where the cdrw icon is pose to be):a

it has power becuase it opens and closes… just isnt read by pc, its read as a hard drive

all help would be appr :bow:

Jumpers in the back set right?

yeah double checked it, does it have anything to do with secondary slave? all of them are turned off except master or could it be the little battery ? when i plug in the hard drive jumper to the to where the cd rom one is connected, my harddrive reads under bios…
