Hard drive disconnecting and reconnecting

Hi

I'm having a bit of a problem here
My external hard drive (a Hitachi 500GB 2.5" drive) which is connected to a Silverstone RVS02 keeps disconnecting
When I plug my hard drive in (With both USB cables), Windows detects it, but after 5 seconds or so it starts disconnecting and reconnecting every second or so
Once a while I get prompts to format the drive

The disconnects do not stop until I unplug the drive, or at least the data one
I've checked my power options and tried almost everything

This is the only USB device that this happens to, and it only happens on this PC so I don't think it's the enclosure
I've tried other USB ports and this also happens


Any help would be amazing
Thanks

  1. Oh and for more info

    This only happens when the data cable is connected to a USB 3.0 port
    When it's connected to a USB 2.0 port this doesn't happen
    The other computers I tried this on only have 2.0 ports

    I've tried updating USB 3 drivers on my motherboard (AsRock Z77 Extreme4)
    This is the only USB 3 cable I have though
    Could it be the problem?

    I recently discovered this problem too.
    What is happening is that usb3.0 has some power saving mode that lets the hard drive power down.
    Here is the fix.
    control panel/power options/change plan settings/change advanced power settings/USB settings /USB selective suspend setting
    The set the plugged in option to disabled.

    So I've tried this and it worked for the first few minutes
    I could read and write data with no problems
    But after a while the problem started again

    Do you know what I could try?

  4. It worked for me. But, I have no more suggestions. I think it is related to the power issue.
    Sorry, out of ideas.

  5. Is it acceptable to bump on Tomshardware?
    Does it even work?

    Bump

  6. In addition to the solution posted above, you should install the latest USB 3.0 drivers.

    Also go into Device Manage and locate the USB Root Hubs, go to their properties, then the power management tab, and uncheck the settings in there.

  9. Hi people,

    I had the same problem, tried the suggested solutions without success. I updated Intel(R)_USB_3.0_eXtensible_Host_Controller_Driver with one compatible with intel's 4-th generation cpu's and it works :)

    good luck!

  10. This works for me. Install the USB drive then shut down your system.
    Restart and it worked.

    Thank you. I was certain my hdd was failing but your solution worked. It's weird that Windows put the ports to sleep even during copying. And I also have an external power supply connected to the hdd so Windows must shut the port down completely not only the power to it.
    Also made an account just to say thank you. You saved me a lot of trial and error.

    USB was originally conceptualised to only be used with short cables (i think 120 cm was the limit). If i am not mistaken, the reason was data throughput couldn't be guaranteed one there was more cable to get through. Over time, manufacturers began ignoring this limitation resulting in issues like the one described here.

    The power saving feature recommended as the first solution did the trick for me, so a thank you from my side. After years of using Tom's as a silent viewer only, i finally created an account to say just this: thank you! :)

  18. Right on!

    Thanks jackjackffm, I first tried the power saving solution and no luck.
    You are correct the length of cable fixed the issue.

    I was using the front I/O USB port on my computer which has a cable from the motherboard to the I/O port and then the cable to the hard drive...total length=toooo long.

    Plugged the same external hard drive cable directly into the USB port on the back of the computer which is direct USB on the motherboard and the now the drive does not disconnect on me.

  20. Hi footwear,

    Have you been able to fix this issue. I have same issues with my toshiba drive. USB 3.0 short cable connected directly to the laptop but tried all suggested methods here with no luck.

    Thanks.

  21. Hi All,

    Same problem here with a Transcend HD 2.5, 500GB.

    Things I tried out without any success:

    - Bought a new cable (double USB plug) - no luck
    - Changed all the Power Settings in Windows 8.1 for all USB ports - no luck.
    - Tried to plug into USB 2.0 ports - no luck

    It keeps connecting and disconnecting.

    Any other possible idea that would help solve this problem ?

    Cheers,
    Sascha

  23. I believe faulty cables are a big problem with USB 3.0. I have many USB 3.0 cables and devices and only a select few will work without continuously disconnecting. Hard to say which brands work best, but when I have a problem, using a known cable that works fixes it.
    Reply to AdobeTX
  24. Found the answer. Needed a powered usb hub. Fixed the problem. The device was not getting enough power. I'm using a toshiba 2tb external hd and a asus transformer t100ta.
    Picked up a belkin desktop hub.

    Seems to fail when I have multiple hd's connected tho.

    Hope this helps.

  27. Part of the problem could be this Intel flaw ...
    http://www.techpowerup.com/181269/lynx-point-usb-3-0-controller-issue-correction-needs-new-hardware.html

    The problem ''went away'' on my Asus G750 when I disabled XHCI in the bios (... also referred to as the USB 3.0 Host Controller specification). https://en.wikipedia.org/wiki/Extensible_Host_Controller_Interface as the Asus G750 has the ''Lynx Point controller'' mentioned in the article. XHCI also handles power to USB devices.

    However, the transfer speed on USB 3 went from 54MB/sec to approx. 9MB/sec -- unacceptable.

    Thanks Intel :P~ for knowingly and deliberately shipping flawed hardware -- engineering vs marketing a classic Dilbert focus -- class action lawsuit against Intel anyone??? !!

  30. My motherboard is an Asus P8Z77-M Pro and my USB 3.0 ports were working well before 2016. Since 2016, they became useless even with the USB 2.0 Flash Drives (using no USB cable extender). They were disconnecting and reconnecting my flash drive endlessly. I suspected that a Windows 7 x64 update had something to do with this problem.

    To fix the bug, I tried to update all my USB 3.0 chipset drivers but it didn't help. I also tried not using a USB 3.0 extender (this can be a cause for this bug).The only solution were to update the BIOS of my motherboard (Asus released a patch on January 21th, 5 days ago). Since the update, my USB 3.0 are now stable and fast (copying a 4 Gb file is around 95Mb/s)!

    I hope this will help you.

  34. I see many different USB problems and associated solutions here. One that hasn't been mentioned is ground loops. I discovered that my back panel USB 3.0 ports worked fine, but the front ones would often disconnect every few seconds when I tried to use a flash drive, for example. Both were run off the same controller and had the same drivers. That’s an important clue.

    This post gave me the idea: https://community.newegg.com/archive_2007-2013/product_support/f/18231/t/43755.aspx

    I took the front panel of my Antec Three Hundred Two apart and found that the metal shroud for the USB ports was grounded both through the cable back to the controller (like it should be), but also to the case. You might think that more is better, but that is not the case. You need exactly one good, solid path to ground. Multiple competing paths to ground cause noise (Google “ground loop”.)

    All I had to do was to carefully cut the extra wires, leaving the one ground wire per USB port back to the controller, and all the ports work reliably now!

  36. Every option listed above is an excellent option-there are many causes for drives behaving like this. For most, cases, un-checking the box in Properties/Power Management for EVERY USB Root Hub in your Device Manager can fix the issue (again, for most but not all).
    I'm going to mention some info I didn't see (or missed) through these answers,any one of which could be the solution to someone's problem. I too had the same problem of my 5TB Seagate disconnecting, and I run a daily image of my system @ 4 a.m. everyday which started failing every morning when I woke up. Here's a few other things I've learned along my troubleshooting....

    This is a rare one, and you can see it tanked his xfer rate, but there can be other power settings in your BIOS depending on manufacturer that might be the cause. Check with your motherboards specs, and see if you have the ability to change any power management options. ***DISCLAIMER-Don't mess with your BIOS if you're unsure what you're doing. If you see a setting you suspect might have an impact, google it and see what that setting does. Not every BIOS is the same obviously, make sure you have the most up to date version of BIOS and Chipset drivers. The Intel Controller mentioned quite a few times here might be the issue.
    CABLES MATTER, but not just length! Just as someone mentioned earlier in this thread (which I cant seem to quote here unfortunately :/ but they said the "Cable was tooo loooong" I laughed but they are correct! The length DOES matter, especially with devices sending lots of data and that require power. It's not just length, but the gauge also - On all of my USB "B" cables (I believe its the "B" one-with the square end we use for printers) the gauges are listed on the wire, either 28awg or 24awg/2c. I have 9 large USB devices (3 midi keyboards, 2 controllers, 1 audio interface plus my drive, Razer gaming mouse, back-lit Logitech Keyboard, etc) for my recording studio. Since they all require power, and some quite a bit of power, its obviously causing a bigger load on my PC. My Audio Interface kept failing, and after hours of research I found I had simply used the wrong cable to connect it. My Native Instruments Audio Interface's FAQ's gives an explanation of the different gauges and I learned then that the 24AWG/2C carries more power and was needed. I had one of my 28awg cables hooked to it. Quick swap to a 24AWG/2C, problem solved. Strangely, on all my USB 3.0 cables, there's no listing printed - but I can see obvious differences in the gauge size of my many different cables. I haven't gotten to the bottom of that yet, but my personal rule of thumb now is I always use the shortest/fattest one I can find.

  37. 9:04 AM 8/9/2017 - I have an Intel NUC that has been dropping the external hard drive with no logging data indicating why. I have a Windows 10 OS. I found a new reason for this. I am using Oracle VM on the NUC. These VMs are configured for the USB controller so I can see the external drive. This was more of a convenience than and necessity. AS soon as I started a VM the hard drive would drop from the Windows Explorer and unavailable. Removing the USB configuration from the VM is what resolved this problem. Windows 10 comes with the Hyper V and I assume that this may happen with that as well. Please remember that if you are going to use the Oracle VM application that you have to disable the Hyper V as there is a conflict. Hopes this helps others with the problem.

  38. I tried several of the solutions in this thread with no success. My computer only has USB 3.0 ports so I wasn't sure how to try it on USB 2.0. I ended up grabbing a USB 2.0 hub with no external power. I just plugged that between my SSD enclosure and my computer and was able to clone my 500gb hard drive on the first try.

    Just as general fyi-type info then, it is a recognized fact in most every electronics related industry that shorter cables are always preferable to longer ones when you have the choice. True with computers, true with audio equipment, video equipment . . . pretty well everything electronics related as I said. There's nothing magical about it . . . think about it this way : a cable carries a signal, right? Does it make sense that the longer that signal has to travel, the greater the possibility of a degradation of that signal? Can be caused by signal attenuation, interference, heck even little physical imperfections in the physical cable itself. Obviously, the higher the cable quality, the more you'll be protected against all of that . . . but still, it's not hard to see that if you increase the length, you're increasing the possibility of problems, even if the overall probability is still very low. General rule though, when it comes to cables, always use the shortest one that gets the job done.
