2.5" Hard drives (40pin, 44pin?)

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

Well my current drive is on the verge of dieing so I need to replace it fast. It rattles when I take it out. I'm surprised it's still working. :? Anyway can I buy any 2.5" drive? Do I need to worry about number of pins or are they all compatible with my connection? A pic of my current hard drive is below. I'm worried will 40 pin drives connect to it? What about the missing hole (pin 20)?

The drive is actually 40+4 pins with the extra 4 being used to select master / slave but they are tagged onto the end of the 40 pins so its easy to get them confused. Make sure you get an IDE 2.5" drive and it should slot in without problems.

Also, alot of 2.5" drives rattle when moved, I have 3 here that do and they are all perfectly servicable. I think that because there is less space inside the drive the heads can move about slightly when they are parked as this allows them to rattle.

qwakrz if you check out the picture I posted the drive connector is 44 pin, the slave/master pins are the extra 4 to the right making 48 in total. Still not sure what to do.

yah.... ur crazy dude.....u cant fit 3 HDD's into a laptop


anyways Gradsy i kno what ur talkin about i got a HDD like that its a spare, did it come with like a cover over the 44 pins to make it "laptop ready"

if it did or even if it didnt u'll be fine buying any ole 2.5" IDE HDD.

Don't worry they all take the same cable, those are extra jumper pins just like on 3.5" drives only in a different place.

no they are not.

u need a 44 pin plug for a laptop HDD. a normal desktop or 3.5" IDE cable wont fit. the pins on a laptop HDD are closer placed and there are 44 pins VS the normal 40, there are also an extra 4 pins for the jumpers after wards.


im positive why? i have a spare laptop HDD and just got an enclosure for it.

all laptop HDD I have run across are 44 pin. 40 are for IDE the other 4 are for power.

Why you are looking for replacing the drive I highly recommend the Hatichi 7K100 7200rpm drive. It will pull 10% more power but you double your I/O speed, to 50-55 mbps. I discovered that productivity went up, I wasn't waiting on the 4200 rpm drive all them time.

i have a 7200 RPM HDD.

I love how everyone just says their opinion as fact when it's wrong. Emerald is correct the 4 extra pins are for power, there are 4 more pins off to the side for slave/master.

My questions is why the debate in the first place? An IDE laptop drive is an IDE laptop drive, it's a standard for chist sake. I have 8 drives of various manufacture and they all look and work the same, imagine that.

If you need to run a laptop drive in a desktop or 3.5" enclosure, get a 2.5ide to 3.5ide adapter, it has a four pin molex like a 3.5" HD that goes into those 4 mystery pins. They cost around $5 on ebay.

now lets see if the noobs understand

Just to confirm for you, the extra pins are for power, all 2.5" PATA drives have them.

Sorry to be pedantic, but you are all wrong -- there are 43 pins Plus 4.
There is a gap in the middle of one row with 1 pin omitted

are the last 4 pins out of the 43 pins used for power? That would explain why I am unable to power it in a laptop or external laptop drive. My pins broke off and are missing. I have the 4 for master slave..

All the data is lost then.. I can't boot the drive...
