External USB 2.0 Hard Drive detected only 10 seconds in the Device Manager

I am running Windows 7 and trying to plug my hard drive 200 GB from an old computer with XP in my new computer via USB 2.0 to an external case.  The external box is its own source of power and requires no drivers. When I plug it into the USB port, I hear the Bell indicating the window detects an external device and she appears under USB devices in Device Manager, but only for about 10 seconds then disappears.  It never appear in disk management or in the computer as a mass storage device.  I tried to use other cables/USB ports. I tried exchanging the external box for a new thought the first one was defective, but that did not help.

Hi Stroke77,

·         Did you get the computer pre-installed with Windows 7?

It is about if the external drive worked when the computer was working with Windows XP or Windows Vista.

Here are some steps that may help you solve the problem.

1. plug in and turn on the external USB hard drive
2. right mouse click on workstation
3 left click on manage
4. click on Device Manager
5 expand the USB list
6 find the USB device to USB hard drive
7. the right mouse click - Uninstall
8 turn off the external USB hard drive
9. turn on the external hard drive USB and let it find and install the driver
10. it should work

  • How to make Toshiba USB 250 GB HARD drive read-only?

    Hello

    I just plug a Toshiba USB 250g external hard drive to replace all the sticks of memory, I've been using.

    I'll use this external hard drive to copy files to other computers and I would like to know how to make the drive read-only.

    Moreover, all the other tips to protect the disc would be extremely welcome.

    I use a Dell with Windows 7 laptop.

    Thank you very much

    Dougal

    I don't know what HARD drive you have exactly, but I know that Toshiba offers a software protection with external hard drives.
    Did you check manuals? Is something like that provided with your HARD drive?

    Maybe you need to use some third party software part for the protection of files on the HARD drive. Google all over the place.

  • Windows Vista does not recognize external USB 260 GB HARD drive

    I have a 260 GB Seagate external hard drive, a laptop Toshiba satellite and Windows Vista Basic.

    The same Windows usually choose the hard drive when I plug it, it does not appear in Device Manager and in disk management, the only way I can get it to work is to uninstall all the USB root hub and then restart the computer, and then reinstall the USB root hub and plug my hard drive.

    When windows finally recognizes him, the only way to find the driver must choose c:\ manually and there's the search for the computer.
    Works for the time that I have the computer hard disk, but when I stopped it, next time I use the computer, I'm having exactly the same problem.

    I tried to remove the hard drive safely and then close the computer and by him plugging back in after windows has loaded, I tired it connected from the computer and tried to close the computer with connected.

    None of these work.
    Can someone help me please?

    Strange?  :|
    But what need s say Microsoft Windows so I don't expect 100% without bug OS ;)

    Disconnect the USB HDD and remove all the USB ports and Device Manager USB controllers. After restarting again the OS should reinstall ports. Then you could try to reconnect the HARD drive.

  • External USB 3.0 HARD drive does not work on USB 3.0 port

    Hello guys,.

    I have a problem with my external HARD drive and the problem is that it is USB 3.0 feature does not work in my computer.

    The curious thing is that it works very well in the SATA port or a normal USB 2.0 port.

    Y at - it a failure with the HARD drive or is there something wrong with my motherboard (M5A99 fx pro r2.0)?

    Thanks in advance.

    From my point of view of the few is not HARD drive problem because the HARD drive operates in a USB 2.0 port.

    I m wondering if you tried to update the USB 3.0 driver.
    Have you tried this HARD disk in another computer / USB 3.0 ports?
    I think that its worth a check.

    Also, I read on some problems of USB 3.0 controller from different manufacturers.
    Sometimes, it might be possible that some problems of compatibility between different devices may arise.

  • Satellite M30X: Problems with external USB 2.0 HARD drive

    Hello
    I have a Toshiba Satellite M30X. I bought recently a 200 GB external hard drive. It has its own power supply. If I connect with USB 2.0 on my laptop, it happens to disconnect and reconnect leads him. Sometimes it works, so I can put data on the disc. Then again, he diconnects and reconnects repeatedly. I've tried a different USB Port, but there is no difference. It's very strange, because I plugged the external hard drive to many other computers (Laptop and Tower) and it STILL works! It is that with my cell phone, it disconnects and reconnects all the time. As I said, not always. Sometimes it works for a half an hour or two and then the action begins again...

    If anyone can help?

  • Wmp54g driver installed, but not seen in the Device Manager

    I'm fighting with reinstalling my drivers of network for more than three days already. (For the history, see http://en.community.dell.com/forums/p/19269864/19470244.aspx#19470244)

    It seems that I finally got the drivers Intel work - however, the WMP54G I had installed before the (I hope) works now driver Intel is not listed in Device Manager. There is no icon in the taskbar wireless connections, either. Another attempt to reinstall the drivers, however, abandoned the process with the comment that drivers would be installed. So, I think the pilot is, but does not at all.

    So, how can I get rid of this driver and try to reinstall another?

    My spec:

    Dell Dimension 9200

    Windows Vista Ultimate x 64 (don't tell me there is no x 64 drivers, please!)

    Seems OK, as I said it.

    Really, it seems that standard LinkSys drivers on the download Web site support not at all x 64 systems. According to the readme files, the driver has not been updated since 2004! This is unacceptable, I think that - as a decent redirect in this forum does not work.

    Anyway, even if some really nice junior contributor on the forums seem to have written some x 64 drivers - himself, I actually did not know how to install without an .exe file. : Pei

    Instead, I did some more googling and learned that the WMP54G v4.1 and v4.0 chips were produced by RaLink and that these guys really provide decent drivers! It is at this point that I remembered my software "Unknown devices" mentioning RaLink, too, RT2500 for v4.0 and RT2561 to v4.1. And well, turns out I have a v4.1 and that their driver is working like a charm. They also provide WLAN monitoring software that allows some additional adjustments. My suggestion: Cisco should outsource their service driver development, too.

Its a backup disk that have been most hard, though don't know if its of any help.

    Hi Deborah,

     

    I imagine the inconvenience that you are experiencing right now. I will help you on that.

    Formatting a disk means configuring the disk with a file system so that Windows can store information in there. Usually, when you install a new hard disk on your computer, it must be formatted with a file system, such as NTFS, Windows can store files that it contains.

     

    Please answer the following questions so that we can better help you.

    1 - is the specific problems of a hard drive?

    2. is it the problem persists when you use different USB ports on the same computer? If 'yes' then tick the question in another computer and let know us the results.

    3. don't you make changes to the computer before the show?

    I suggest to follow the steps below and check. Please move to the next, if only the problem persists after completing each.
