What hard drive do I need, and what is the connector called?
Hi! So I've never worked on Airs much, and then I came across a few of them. One powered on (model A1304) but was missing the hard drive. Easy enough, I thought. One of the other Airs (completely dead) had a hard drive cable, so after buying a 120GB "MacBook Air hard drive" on eBay for $70, I thought I'd be all set. However, it turned out that the cable from the other machine had a different connector on the logic board side than my working machine (machine's connector is squarish, whereas the cable's connector is more rectangular). So the next step was to buy the appropriate cable on eBay. It came in today, and the next gotcha is that the cable on the HD side is only half the width of the connector on the HD, so (I assume) it won't work with my drive. I was not aware there were different connectors on these hard drives.
Question is, for all you people more familiar with these tiny hard drives than I am: What are the variations (small connector vs wider connector) called? Is it the SATA vs PATA versions of these drives? I need to purchase yet another drive to finally finish up this Air, and I don't want to make another mistake, so it would be useful to know the proper terminology.
UPDATE: I've uploaded a picture showing the two cables, and the two different connector types on either end. As you can see, one fits and is the same width as the connector on the hard drive, and the other is too small.
