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

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?

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

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

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.

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!

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

I'm on intel's site but I'm having trouble finding the driver. I'm at this address.

This worked for me. For me it was a WD drive and it was really annoting because i had all of my steam games on it and when I was in a game it would close down. Thanks!!

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! :)

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.

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.

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

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.

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.

Yep worked here also. Was using a USB3.0 extension to save reaching round the back. Used just the HDD lead and worked a treat. Many thanks

Part of the problem could be this Intel flaw ...
http://www.techpowerup.com/181269/lynx-point-usb-3-0-co...

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_Controlle... 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??? !!

Thank you! This did the job. It was the USB 3.0 controller, specifically. That saved me much bother.

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.

Like many others I have spent hours trying to resolve this problem. The fix for me was to replace a missing a missing program. try downloading C + + from Microsoft. this replaces missing DLL files.

Good luck.

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_...

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!
