The drive you require is known as an OEM hard drive. Unfortunately part of the confusion comes from the fact that the drive you require is not able to be purchased outside of Apple. It must have been very alarming to find you purchased the correct matching part number but cannot connect to two missing pins, I can understand how you feel. My name is Angel, I am part of North American support and I would like to assist you. Our EMEA support team has closed for the day. “Thank you for contacting HGST Technical Support Center. I think if they removed the pins the P/N should be different… am I right? Unfortunately the new one had the slot but the 2-pin were not there!! The only difference was the manufacturing date, the one I bought is from APR-2015 and the one in YouTube from JUL-2013, so take care that recently (also for same models and P/N that theorically include the pins!) the hard disk are not exactly the same in function of release date and may not include the pins. (I saw in YouTube a guy opening the same HDD with these 2-pin). I bought an Hitachi (formally HGST, the Deskstar one) making sure the new HDD includes the slot with 2-pin for temperature readings. Hi, probably you already upgraded your iMac, just in case other people had an Hitachi inside late 2009 model. We even provide helpful instructions with our step-by-step installations videos!

OWC announced today its In-Line Digital Thermal Sensor kits, which makes the brand-for-brand drive swapping a non-issue! With this OWC solution, all the compatibility issues are fixed and you’ll be free to upgrade your iMac with ANY brand 3.5″ SATA hard drive. Our former recommendation of swapping out brand-for-brand is now outdated, but that doesn’t mean we’re leaving our customers high and dry.
So thermal pinouts on some drives had started changing and other drives no longer even had the thermal sensor pins to connect to in the first place.
Since 2009, several of the major hard drive manufacturers have merged companies and technologies. Fewer and fewer drives can actually still be swapped brand for brand.
