If you're following the technique I've outlined, it's wise to try booting from the new external SSD before installing it internally, just to make sure the computer recognizes the drive as bootable.
That way, once you restart the reassembled computer, you can at least be sure that there's a drive with a bootable operating system available.
clone the operating system+user data from the internal HD to the external SSD using Disk Utility, SuperDuper! or Carbon Copy Cloner (you can also do a clean operating system install by downloading an installer from the App Store and installing it on the new drive).attach the SSD as an external drive first through USB/FireWire/ Thunderbolt.What steps have you already taken? If you can give us a detailed list of the things you've already done, in order, it will be easier to determine where the problem is.Ī common technique to replace an internal boot HD with an SSD would be to: Of course, if the way you installed this SSD was to remove the previous internal HD and install the SSD in its place, without formatting the new SSD and installing a bootable operating system first, then there's no operating system or formatting utility at all. Unless the operating system on the old boot drive posts a dialog box offering to format the unrecognized drive, the computer doesn't "detect" anything because there isn't anything the operating system can speak to yet. The cable model number is written in white on your broken cable.A new internal drive normally ships unformatted. Cables are NOT interchangeable since they come in entirely different lengths and won't fit right. There are 3-4 different cables for 2009, 2010, 2011, 2012 macbooks so get the right one.
Fortunately it is easily purchasable for $10-25 on Amazon (as of 2021) and was pretty easy to install with only a small philips screw driver. Tape is not meant to hold the cable in place, it acts as a comfy bed for the cable.Īpple later made a thicker cable with a diferrent model number to address this issue. If you have a Macbook with a non-removable battery, press and hold ' Shift + Control + Option + Power ' for 15 seconds. The electrical tape backing is quite a slippery and smooth rubber surface. Press and hold the Power button for 15 seconds.
In the future, place electrical tape on the rough aluminum to reduce abrasion. The cable is the weakest link since it is sandwiched between your hot HDD/SSD and the rough brushed aluminium macbook. This cable's copper is fractured and transmitting data incorrectly making your Mac believe that it cannot find the boot HDD or SSD. The problem was the internal thin black flexible cable (less than 1 mm thick) that connects the drive to your Mac's motherboard. I thought my 8 year old OCZ Vertex 4 SSD was the culprit since my 10 year old Vertex 2 died in a Toshiba laptop. My Mid-2012 Macbook Pro 13" randomly stopped working due to this issue.
