Resolution, Prevention, and Closing Thoughts

In our case we were fortunate. The data pins on the SATA connector were fine, we simply didn’t have wafer to hold a cable on top of the pins. We ultimately managed to find the piece of the plastic wafer that broke off, and with a bit of tape MacGuyvered a solution with another, particularly tight SATA cable that allowed us to get the drive back in to working order. But this is luck on our part, just finding the wafer, let alone is breaking in a manner that allowed us to enact this fix is not common for other computer owners we’ve talked to with this problem.

But as we mentioned in the opening of this article, what happened to us was completely preventable. We’ll freely admit that what happened was due to negligence, and could have been avoided with a little more careful consideration. How?

By far, the easiest solution would have been to use the right cable. A latching cable would have prevented some of the downward deflection that caused the connector to break. A better solution however is to have used an angled SATA cable, in which one connector is at a 90 degree angle. Using a right-angled cable would have made our SATA flow along the width of the case rather than the depth of it, allowing us to avoid routing a cable towards the fan, and avoiding the need to bend it so sharply that it exerted any significant force on the drive’s data connector.

Unfortunately angled connectors are not a common part. Because they’re not practical to use in every situation (mainly those where the cable needs to be going the other way) we do not see drive manufacturers or motherboard manufacturers include angled cables with their products, instead they ship with traditional straight cables that are acceptable in most situations. This situation requires a builder to have the foresight to purchase an angled cable separately (a quick search on Newegg found one such cable for $2) which was what we were initially lacking.

Another option for our case would have been to go with one of a small number of reinforced SATA cable devices. The most notable of these would be the now-discontinued SecureConnect cable, which is functionally a cable with a far larger connector on the drive end that secures itself against the drive. Unfortunately Western Digital went with a proprietary route here in order that the enlarged connector would have something better to hook on to by putting extra pits on their hard drives, which means the cable can’t be used on non-WD hard drives like ours. There are a few smaller parts manufacturers that make similar devices that will work with any drive, but these wouldn’t be quite as secure; we do not have any on hand to test but we believe any such device would have still prevented the drive’s connector from breaking (and yes, we’re aware of the irony of such a device further closing the already small space between the drive and the fan).


Closing Thoughts

No matter how we decided to go about reinforcing our setup however, the point stands that in hindsight we should have done something as we had a situation that was likely to (and did) result in a connector breaking. We were fortunate that it broke in a manner that wasn’t a fatal problem (and that we found the bit of plastic wafer that broke off), but this can be a fatal error.

The moral of the story, and the reason we even bothered to publish this article is to share with you the reader an analysis of what happened, to pass on what we learned so that it doesn’t happen to you. The vast majority of computer builders will never even find themselves in a situation where they can break a connector, and even then only a fraction of those builders will actually break something, but it does happen. And out of any hardware that can be broken, most of us would rather lose anything else before a hard drive, due to the desire not to lose the data stored on it.

Our lesson then is this: don’t hesitate to use additional hardware to hook up a SATA drive if you’re in tight spaces. An angled cable is only a couple of dollars (and will likely outlast any other system component) can prevent turning a hard drive worth a hundred times that value from turning in to an oversized paperweight. The SATA connector is by no means fragile, but it’s not abuse-resistant, it requires a little more care than most of us are accustomed to when it comes to hooking up hard drives.

As is often the case, the effort to prevent the breakage would have been easier than the resolution.

    oh, beaten by about an hour, lol oops.

    It would be neat if they used a connector like the breakout box for VGA/DVI on the Macbooks. They have basically a little nub, approx 1/4 inches thick and 1/2 inch wide with about 1/4 inch of depth, with the contacts on either side. The cable is a male connector with the female on the unit. Quite possibly the most robust way of doing things I can think of at this scale.

    This first time I couldn't get the drive to be seen again by the OS, so I was out of luck...the second time, I had enough of a connection with my quick patch, to allow me to recover the data. I have to agree that it's all my fault that it happened, but in these modern times, did no one on the SATA committee see that this would be an issue? It's a really flimsy connectory...with no housing...It takes almost no force to break on off and the connectors stick out so darn far that the torque from their own weight plus the cable is a continual strain on the connector. This is something that should have been fixed IMO.

    To be fair, they already have done a bunch of work to fix the problem. Talking to Knut, we get the impression that the problem is very uncommon these days.

    The funny thing is that it seems to vary a lot depending on the manufacturer. For the photos in this this article I broke an old Maxtor hard drive rather than pull apart the repaired drive for photos. The Maxtor refused to break, in spite of bending it far harder than I ever did with the original broken drive it still took some time to wear it down. I can't imagine why, but it seems like some of this is just a roll of the dice, with the plastics used in the connectors not always holding up to the same conditions.

    Same for me, im going to glue them today hopefully i'll get a conection.

    I'm sorry that I don't share in everyone else's enthusiasm, but this is probably the most pointless article I've read on AnandTech to date.

    Then why did you read it, and then take MORE time to post a comment? I come across articles all the time that I don't find interesting. I've found that by ignoring them, I can save a lot of time. You may find it will work for you, too . . .

    This is an issue I hadn't really thought about before when building my PCs, and now it's something I'm going to be watching out for more in the future (and I'm going to be checking my SATA connectors when I get home to make sure they're not being strained), so if reading this article prevents me or others from breaking a hard drive at some point, then it was hardly pointless.

    There's more to building PCs than looking at benchmarks, so I appreciate articles like this try to make the PC builder's life a little bit easier.

    I've done the same thing before while trying to reposition a drive in a case... I didn't think I ever put too much stress on the connector, but it snapped off the same way, with the pins still on the drive and the PCB stuck in the cable end. I was able to carefully slip the cable end/pcb back over the pins, though I should probably glue the cable to the drive so the pins don't snap off at some point.

    I'd just like to say thanks for this article. I'm building a new system right now with a 182 case. When I order the drives I now know to order the SATA2 cables with a 90deg bend with them too. You probably saved me a lot of frustration. Keep it up.
