Replacement 120gb HDD not recognized in MacBook Air A1237

Hey guys,

I just bought the 120gb Samsung HDD from IFixIt for my 2008 A1237 Macbook Air because the original 80gb HD died. I followed the install instructions implicitly and no matter what I have tried I can't get the HDD to be recognized by disk utility. I have checked the cables and made sure everything is secure and I still get nothing. Any tips on what I am missing or could try?

Answer this question I have this problem too

Is this a good question?

I'm finding that the newer SATA drives have to be jumpered down in speed to work. Put a jumper across pins 5 & 6 and see if it works. This should set it to 1.5 GB

UPDATE

Sorry, I forgot this was the original 1.8 hard drive with out the jumpers. Try watching this video and see if you missed anything: MacBook Air (Original) 120 GB Hard Drive

You are trying to format and partition the drive before using, right?

Sorry for my ignorance but how do I jumper down the pins? Also won't that void any chance I have of getting a refund for this HDD if it doesn't work?

There should be 8 pins next to the power plug. 5&6 would be the third set away from the molex plug. It's just a little removable jumper like used on old IDE drives to set master & slave. In case that's not it, here's Samsungs instructions for formatting on a Mac: http://www.samsung.com/global/business/h...

Okay thanks for the description. I will give this a go and see what happens.

Im familiar with how to change the jumper on a normal hard drive but this tiny Mac HD doesn't have any visible jumper or pins on it.

So to clarify are these jumper pins on the power plug running from the MacAir battery cable?

Hi,

do you mean the disk utility that runs from the remote install program on another Mac or the installation program for Mac OS X?

My new hard drive was not recognized when I wanted to install Mac OS X. There was no destination HD shown. Then I went to the disk utility program (under installer) and there it was. It was unformatted, so I formatted it as Mac OS extended (journaled).

After that the installation program recognized it and I could chose it as destination volume.

It looks like there are at least 3 different ZIF-PATA connectors. While the drive that shipped with my MacBook Air, Model 1237, was a "Type-1" according to my source, the drive I purchased to replace it (a Super-Talent drive) is a "Type-2". I just had to flip the latch and Disk Utility recognized it! A google search led me to a page from Active Media Products (RunCore drives) but I couldn't verify whether or not the information was standards based or if there is no standard and these are just in-house implementations. Hopefully this helps, good luck!

I had same problem after installing a new hard drive on my original MBA. I had to fish around for my install OSX disk and holding down "C", was able to get it to read from the CD. Then had no HD to install os on. Went into Disk Utility and selected Partition. Created 1 partition and voila the hard drive appeared. Thanks IFixIt for the tutorial. I am a novice but it was so easy to follow. Totally saved me several hundred dollars on a new HD with less memory from Apple.
