Tecra S3 external drive usb disconnects on all usb ports

Hello

I have a Tecra S3 with the following problem:

When you work with external storage devices, my devices disconnect by them - same (somethimes) after somethimes 5 minutes after 1/2 hour and when working with multiple devices all devices disconnect at the same time, a place of the problem on each usb connection.
I tried various storage devices such as sticks of memory cards sd with a usb adapter and hard drives.
How can I tell if the problem is hardware or software partners?

Greetings,

Marco

It seems that your usb devices sometimes need ampere more supplies (500mA max) usb port.
Establish an external usb hub and connect your storage devices. The usb hub must be active (with adapter)!
It should work.

  • What brand of external drive USB/eSATA can save a Virtual Machine to host Windows 7 operating system?

    People,

    Hello. I use 3 Player VM and Guest OS Windows Server 2003. The host OS is Windows 7. I need to increase the size of the VM disk, so who can install several systems in the guest OS. Before you increase the size of the virtual disk, I need to back up the virtual machine hard disk external. It is to copy and paste the "C:\VirtualMachine\" folder in the hard disk external.

    I just bought an external hard drive that is "Western Digital My Passport Essential 500 GB USB 3.0" and its software is "WD SmartWare". It seems that the software can back up the entire hard drive only. Alternatively, the backup files by selecting the types (music, photo, document, movies). But can not save a folder "C:\VirtualMachine\".

    So my question is: what brand of external drive USB/eSATA can save a Virtual Machine to host Windows 7 operating system?

    These two questions do not apply if you have a virtual machine.

  • External drives, USB, USB Flash Drives, "driver software device is not installed. Problem Acer and Windows 7

    Not sure one I'm more frustrated with.  Acer or Microsoft

    Try to get decent customer service out either seems so difficult.

    OK, it's a pretty common problem.  I've seen this around other forums and each finger to Microsoft points.

    Flash USB, Jump Drives thumb drives, Memory Sticks, players, whatever they are called, they do not work on my Acer laptop.  Everything works still perfectly on my Vista PC and my work XP.  So they are not damaged.  Also an external Freecom USB 1 TB drive.  Does not work on Windows 7.

    I have an Acer 5338 (less than one year) which unfortunately as as a manufacturer OEM for Microsoft Windows are not interested in help to say that there is problem Acer.  ACERS site does not even recognize the existence of the cell phone model I which makes contact them for a solution physically impossible (everyone has a phone number or e-mail address >).  In any case, they had a free upgrade to Win 7.  (Oh you can't imagine how much I care that I didn't...).

    So I've updated.  And all USB memory devices do not work all of a sudden.

    All of them try to load drivers then give up with the error message.

    Just to get the usual answers to the road!

    • I tested the USB ports.  All work.
    • I uninstalled all the USB ports and let the Win 7 to reinstall. No problem
    • I deleted the file that records discs.
    • I made a new clean install.  Nothing has changed.
    • Cannot switch the chipset drivers.  Won't let me, says I don't need them
    • Each drive is displayed during the startup screen.
    • Each drive appears in Device Manager but the poster as a fault.
    • Updated installed, removed, re-installed all the drivers on the planet.
    • Tried the solution of "regedit" suggested elsewhere, temptation of power my laptop, lucky I system restored to the top.
    • Does not appear in disk management, so cannot deal with any drive letter conflict.
    • Have no viruses.
    • Have one firewall installed.
    • Prayed
    • Touched the thing of reversal
    • Pleaded
    • Pretended to cry.  Not interested.

    So, I'm hoping against hope that someone has a solution to this problem.  I have a vague idea that it might be something to do with the "ports" and the port settings.  I'm afraid is a closed book to me, so please, geniuses everywhere, please help!  Give me something new to try!

    Or a way to talk to a human being at Acer!

    Hi davec07510,
     
    We use Windows 7 and have not encountered this problem on computers. This issue is occurring on your computer may be due to the driver or hardware that does not support Windows 7.
     
    The compatible chipset driver installation Windows 7 can help.

  • External drive USB 500 GB PX1394E burp and more

    Since yesterday, my external 500 GB Toshiba USB drive burp more.
    The LED becomes red instead of blue when I turn it on. Needless to say that my entire CD collection is on it, so it is quite a mess.

    What are my options now?

    I bought the external drive in Germany, a little less than a year ago, model Toshiba PX1394E - 3 50.
    Stupidly, I can't find the receipt anymore, so it won't help if I just bring it back to the shop.

    Where Toshiba can I apply for?

    How can I open the case to see if the drive is broken, or just the USB interface?
    The enclosure has two small screws, but by unscrewing seems to have no effect, it seems that they are just to fix a foot plate support.

    Help, please! It is a nighmare!

    Thank you kind
    Ulf

    > How can I open the case to see if the drive is broken, or just the USB interface?
    Don t what a controller can be broken. If something is broken, then this might be just the HARD drive.

    If the HARD drive burp more then the hardware failure is possible and only a replacement can help you. Stupidly that you can't find the verification of sales because it is necessary to get a replacement under warranty

  • Deletion of images when the external drive is disconnected.

    I shared my images between the local storage and 2 TB external hard drive.  If I delete a picture when the external drive is not connected it will erase the image next time the reader is turned on?  If this isn't the case, I guess I'll have images that are not in the catalog more on external hard drive if it was not connected when I press DELETE.  Thank you. Ian.

    Hi IanLivesey

    Lightroom keeps a catalogue of your pictures stored somewhere on the network no disc. If you delete an image you can delete in the catalog or the catalog and physically. To remove an image physically physical storage must be fixed.

    If you only remove the images from the catalog, they will remain on your hard drive. You can remove these images subsequently with the tools of the operating system.

    Kind regards

  • Data on external drive USB store

    According to the guide configuration (v4.1, p76), you can create a data store on an external usb drive connected to the host.  I have no problem seen VMs see and use USB host drives, but I don't see the USB on the list of storage adapters, configuring the host tab.  (I made sure that the USB is not assigned to a virtual machine).

    Y at - there a trick to this?

    You cannot use a USB device to store virtual machines - it can only be used as the virtual computer device can attach to and yes I know the documentation is somewhat misleading.

  • USB ports all failure Tecra S1

    Hello

    my old Tecra S1 video card died last week and I managed to find an another identical Tecra S1 very cheap.
    I swapped my portable hard drive in the new computer and everything works fine apart from any of the USB ports work.
    Food sent to external drives USB but my computer does not recognize one of the 3 USB ports at all.

    I tried to remove / replace the drivers but no change.
    Also as I had my same old laptop for spare parts I have even replaced the USB turntable (as one of the original USB ports has been damaged) but still no change.

    Could this be something to do with the version of the BIOS on the laptop as surely everything else should be already on my hard drive?
    Maybe my old laptop had an older BIOS which might make a difference?

    any help would be gratefully receieved as I looked the net but don't have anywhere!

    Thank you very much

    Hello

    First of all, you aren't sure if the USB port hardware is ok for this second Tecra S1. Right?
    So, theoretically, it might be a hardware and software problem.

    Generally, the USB ports are controlled by the chipset driver.
    You replaced the HARD disk where the operating system is already installed
    I think you should try to install the operating system once more on this second Tecra S1.
    Then you should check the Device Manager if all the USB ports have been recognized correctly.

    If the USB ports would be NOT visible in Device Manager, then I would tend to a hardware problem

  • Tecra S2: HDD as unknown device on two of the three USB ports

    But when I plug my external hard drive in two of them, it says that it is an unknown device...

    You said external USB HDD appears as an unknown device on two of the three USB ports.

  • USB PORTS NOT EXTERNAL SENSORS

    I have 3 usb ports on my laptop HP Clubhouse.  Have never encountered a problem like this in the past.  I can use my external mouse, USB port will not read a flash drive or an external hard drive.  I checked the Device Manager and there is no error message, and all USB ports are read as working properly.  I installed all the news updates and drivers and still nothing.  I could understand if I was to receive error messages which is however not the case.  Is it possible that all 3 of my USB ports would die at once, and if so, why all this bed as usual.  Help, please!
