When do I need to worry about the hard drive cable?

I have a 2011 13” MacBook Pro, which replaced a 2006 MacBook. I did not need to worry about the drive cabling on the 2006, but I know this is an issue on the aluminum unibody series in general. While I am going to do it in the future, what should I look for that tells me there’s an issue with the cable and I need to get it done sooner rather then later? The plan is to do it once I decide to install a better hard drive and replace what I assume is the original hard drive (Toshiba MK5065GSXF).

At least for now, my current plan is to leave it be until I’m ready to replace the hard drive in the system, as I know this is when the issue becomes obvious with the 2011 cable.

If I start seeing potential signs of cable failure, what do I need to look out for? I don’t know if it’s been done, but I am going to assume it hasn’t been done until I see the cable has been swapped and protected before I consider the cable a done deal.

If the drive you are using is a SATA II (3.0 Gb/s) HDD or SSD then you can coast until you’re read to upgrade the drive to a SATA III (6.0 Gb/s). Thats if the cable is a SATA II rated cable (original)

You can look at the cable for tearing and for abrasion or if the bend are bent sharply all of these cause cable failures.

P.S. Got your email thats one clue there are a few others but you get it! There getting good!

I'm still running the presumed original SATA II drive. The plan is to let the 30-day return window expire before I start messing with it, at which point I'll check the cable and possibly replace it so I know I'm SATA III ready, depending on the price to do so. What scares me about the adapter is someone was probably going to use that adapter the machine came with and fry it if they didn't know.

I have photos to show you how close it is if you want to see how far they've come. I've left the item ID the seller used for stocking because on one because I have no intention of using it but it's disturbingly good.

I bought a known good one early as an insurance policy if it turned out to be yet another copy since I saw it coming from a mile away with how many are out there. The family ID seems to be the best clue I've found to spot these and works very well when used with the other signs (cable feel and print being too dark). The weight also gave it away, but some of them are dead close within a few ounces as I found with a previous 60W I got rid of. I'm not revealing the magic numbers I use to confirm it's real, but what I caught is a dead giveaway.

In case anyone is wondering, I used the pre-fried one I got stuck with since I had questions about its authenticity.

@danj correct me if I'm wrong but I'm presuming I now own a system that can't be cloned anymore once I get a new drive? At some point I am going to put a modern SATA III drive in.

I think I'm not able to but I'm used to the era when cloning was still viable.

Its best to let the OS installer setup your partitions and install the OS as needed, then us Migration Assistant to move your stuff over from either an externally connected drive or other system. I haven't used cloning software for quite a few years! I think the last time was with Mavericks.

@danj Yeah... This is a 10.11 system. I think I'm dealing with a no cloning release where you begin having issues. I didn't get a cloned system since internet recovery works. It may have been a High Sierra system in the past from what I seen in internet recovery too.

From what I know I can hook the old drive up as-is and do it that way but having a Time Machine backup probably wouldn't hurt either.

完成的

@danj Yeah... It needs to be done which is why I went under the pretense it wasn't done until I opened it. I found an 821-1226-A cable installed, which is 100% confirmed to be the SATA II cable. Didn't show up on the iFixit listing for the 2012 system.

Not going to bother protecting it since it needs to go anyway and I want to retire the spinner for an SSD when money permits - it was left untouched, so it's probably not worth trying to protect it since the damage may be done if it acts up.

It looked okay, so I can coast without fear until I'm ready.

I suspect it's probably original and unprotected knowing which drive it came with. I will probably need to make those changes along with replacing it.
