I need to get a new hard drive for my laptop. My concern is with the pins on the connections. My current one I believe is a 44 pin drive, one of them is missing in the middle so it's really 43. After looking around online I came accross a few which are 40 pin in the description, and 44 pin in the description. Does anyone know if a 40 pin one would work with my connection? Are the 40 pin drives newer and the 44 pin ones older?

Most of the descriptions for 2.5" drives online don't even mention how many pins are on it, does this mean they all work in all connections, or are they leaving out important info? The images often don't show the side with the connection either. I've only seen ones with 44 pins so I could be picking it up wrong but I have seen a drive description with a connector type: 40 pin idc

Dunno. But when I changed my old laptop HD I bust the little device that plugs into the HD (couple of pins bent and snapped) and then does a hinge type effort to plug directly into the MB (can't have HD standing straight up in a laptop obviously). Well worth ordering one of those at the same time. Only costs a couple of quid and totally annoying when you don't have one. Went absolutely everywhere (inc. a Maplins shop) and no luck (even took it with me to show them). Ordering online was the only answer. Two weeks later answer. Grrr.

Oh, and I'm guessing the extra pins are probably unneccessary. Like Scart plugs.

Cheers

I am 99% probably lying in bed right now... so don't blame me for crappy typing

The first 40 pins are identical to the pinout for a standard IDE interface.

Pins 41 and 42 are +5v power supply for the HD, 43 is power ground, and 44 is drive type (ATA or other)

So if you ordered a 40-pin laptop drive, either they've come up with a new way to squeeze the power into the existing 40 pins, or it has another connector for power.

I haven't ordered anything yet, still trying to make sure I don't buy something that's not compatible. Do I need to worry about how many pins or will either work?

I've attached a diagram of my curent hard drive. The connection it plugs into matches it exactly. I'm worried incase the 40 pin drives don't have a pin missing in the same location. If not they won't plug in.

Any links to these 40 pin drives? Google just gives me 2.5" to ide adapter cables. Sure they aren't actually poorly labled 3.5" drives?

By way of demonstration, he emitted a batlike squeak that was indeed bothersome.

The link below has a 2.5" drive with 40 pin idc listed as the connector. I haven't seen many listing the number of pins so I'm guessing they must be all able to plug into the connections. I looked up some images of drive below however and counted the pins and there seems to be 44, although you can't trust images, it could be a different model.
