Thanks! Even so, I had to get the drive aligned just right, so that the sliding bar could mate with the matching slot in the case.
I suspect that the plastic positioner will secure the drive well enough (for this style of adapter). As I mentioned in earlier comment, this should mean you can replace / upgrade the SATA drive later without needing to remove the adapter, skipping many steps.
Backstory is that I put an SSD in the adapter a few years back to replace a dead optical drive. And it worked with the extra drive, but it seemed to function slowly, at optical-drive rather than SSD speed. Recently, the machine stopped detecting the extra hard-drive. I don’t know why. My guess is that in an upgrade something changed in how the kernel detects devices, and it got confused by an SSD being where it expected an optical drive. (I’m running Debian GNU/Linux, it being the only way I can run up-to-date software on a machine no longer supported by Apple, and I’m a Free Software enthusiast anyway.) Your mileage may vary… Because the SATA drive wasn’t being detected, and I needed access to the data on it, I had no choice for the time being but to take out the SSD and go back to a single-drive machine. The main drive is SSD, and I’ve upgrade to the max 6GB RAM, so it’s still a pretty useful machine.
I’m planning to put the adapter back in, just in case the void would be bad for cooling air-flow.
Note, if you’ve already installed an optical/SATA adapter, and you’re doing this just to replace the SATA drive, then you might be able to skip almost all of the following steps. It seems that for the sort of adapter described in this guide (with the drive secured by a plastic positioner), you should be able to leave pretty much everything in place, and swap out the SATA drive (though you might need to move the Bluetooth antenna holder out of the way).
Unfortunately for me, mine is a different kind of adapter, with the drive secured by screws from the underside, so I still had to go through almost all the steps to get the adapter out. I can’t even remember where I got the adapter. I think it was probably from iFixit, but it might have been a different, earlier version.
I pulled firmly on the tab, while rocking back and forth slightly.
Getting the upper-case/keyboard off was a bit nerve-wracking. Just work away at it carefully, bit by bit.
A small torch (flashlight for our American friends) was handy to see what was happening underneath the upper-case. Otherwise too dark.
I used a photographic lens-cleaning blower (with the rubber squeeze bulb, just the blower, no brush) to get away the dust. Probably not as effective as canned air, but it worked well enough. I’d recommend avoiding touching anything with the tip of the blower. Keep it a few mm away.
Yeah, I found PH #00 better too. (For black 2.2Ghz A1181.)
For black 2.2GHz A1181, I used PH #000 as suggested by guide. My screws are both 6mm.
Yeah, same for me, #00 worked; #0 suggested in the guide was too big. I didn’t even try #000. For 2.2GHz A1181. My screw config matched the guide, 3mm in middle, 4mm on the sides.
