i have a hitachi internal hard drive that died. i replaced it with a new seagate. Anyways troubleshooting i bought an identical hitachi hd, which was made in feb of 2009 and my original was made in june of 2009, figuring it might be a bad pcb from my computer overheating. So i did the swap with the new pcb and plugged it in via usb, and the good news is that my discs spin perfectly and no abnormal sounds or clicking, but my comp wont see it and i cant find it anywhere, bios, disc manager, disc management.... not anywhere. Unless i am overlooking something or maybe a firmware issue and if it is a firmware problem how can i update it and where do i go to get the update. how would i even update it if it wont even recognize that there is anything there? Im at a lose and need some guidence. there has to be a simpler salution than sending it off and me taking money out of my daughters college fund just to get it repaird.
thank you and God bless to everyone and anyone who can solve my problem.

Hi, you need to swap the nv-ram as well from your old board to the new one.

i have two small 8 pin chips, which one is the nvram or are they both nvram? and any good tricks on doing that switch. i have a brush pin that i bought at radio shack and the guy there said it would take off solder, is that true or do i have to heat it up. also if the pin does work like he explained then i also purchased a conductive adhesive meant for chips, will that also work instead of having to solder.
