External Toshiba HARD drive not recognized on USB 2.0 ports, but only on USB 3.0

Hello

I have a Toshiba drive external HARD 750 GB USB2.0/USB3.0
Now, this HARD drive is not recognized on USB 2.0 ports from my laptop (same thing on my desktop computer) but only on the USB 3.0 port.

I have try on port USB2.0 computers different (desktop, laptop) but it doesn't work. The LED is the lightning, but the drive does not appear in the file Explorer.

You have any ideas?

Thank you

> Now this HARD drive is not recognized on USB 2.0 ports from my laptop (same thing on my desktop computer) but only on the USB 3.0 port

USB 3.0 port 900mA feeds. The USB 2.0 port common provides 500mA.
I think that the HARD drive needs more 500mA power in order to work properly.

So if you want to use the HARD drive on USB 2.0 ports, I recommend you to use a USB Y cable which allows to connect the HARD drive to two USB 2.0 ports

Today, I started the PC in the morning (with no updates of Windows or other software) to find that he would recognize is no longer the Toshiba hard drive. He always recognizes the WD drives and SimpleTech drives when they are plugged. All external drives are powered separately and do not rely on the power of USB.

    I tried the Art Store on other PC and it works fine. I tried to change the cables, the cable works on other players (and other cables will not do this work of Art store). I tried several ports USB 2 on the PC, with no luck * (but all the ports work with other readers).

    I try verified Drvivers of COMPUTERS and MANAGING disks. There is no sign of the disk (not defective disc), it is simply not there at all.

    I searched on the web - try a variety of techniques (disconnect the power PC) and much more. No luck.

    Unfortuantely, Apple did not update the firmware on the USB key (it is still 2.0) port on their routers for a number of years.  As a result, new USB 3.0 drives may or may not work with airports.

    Yes, we know that USB 3.0 is supposed to be backward compatible with USB 2.0 in theory, but theory does not always work in practice.

    If your drive is formatted as Mac OS extended (journaled)... also called HFS +... .and you have tried the drive with and without a USB hub powered and the reader will not be displayed with you check using the AirPort Utility disks tab... then you have one of a number of readers who do not work with routers from the airport.

    I just checked a new LaCie USB 3.0 drive I have here. It works perfectly with a Mac, but it appears not at all when I connect it to the USB port or a powered new AirPort Extreme or new Time Capsule directly, or by using a USB hub.

    Hi potters.

    What model of laptop you have exactly?

    It would be important to know because if you have a model that uses SATA hard drives need drivers Intel Storage Manager you can install Windows XP.

    My BIOS is very, very basic and is not very many options.

    Would be - that the problem be attributed to the speed (7200) faster or the power supply to the new HARD drive?

    The service guide says that you have a hard drive configuration 2 x 320 GB 5400 RPM, but I don't think that the speed must be at 5400 RPM. However, the speed of the two drives should be the same I guess. As 2 x 7200 rpm or 2 x 5400 RPM...

  • Hard drive not recognized by BIOS in Dell Precision T7910 workstation

    Greetings,

    I recently acquired a Dell Precision T7910 workstation without all the hard drives installed, so I went to the store and buy a 240 GB Sandisk SSD put in the hard drive and then installed caddy caddy in port 0 (I also tried port 1 with the same results), and then I turned on the computer and it says "no drives found" press f2 to enter setup or press f5 for the diagnostics. I think there is probably a setting in the BIOS to configure the hard drive that I'm ignorant, so any help would be appreciated.

    Is there a CTRL-R (or another command CTRL during POST) to enter a for the LSI controller configuration utility? Possible that if installed/enabled, ports are managed by the controller LSI instead of the BIOS. However, I have not a 7910 to watch... just go out how it worked normally.

    The hard drive worked well until KB2398632 & KB2347290 updates have been downloaded and installed on 16/09/10.  Hard drive works fine on my Vista machine at work.

    On my own machine (Windows 7), the drive is seen in my BIOS.  He also appeared in the "features and properties" of the control panel Windows 7 and the 'properties' indicates that the device is functioning properly.  The pilot is also updated.

    It does not appear in the Windows 7 Explorer under 'computer '. Only the C: drive is indicated.

    My AMD South Bridge set drivers are up to date my USB 3.0 being drivers.

  • Re: Toshiba Store Art Exteranal 320 HARD drive not recognized

    Hello

    I have a problem with my 320 GB Toshiba Store Art HDD Exteranal.
    I bought it a week ago and everything worked well on different systems: Win 7 (64), Vista (32), XP Pro.
    But today when I tried to use it it displays a message that * unrecognized device * and it cannot install the driver for this device.

    Unfortunately there are no drivers to download for this device drivers Toshiba page.
    I checked it on Win 7 (64) and Vista (32) - same problem.
    I remember, the last time that I used it was on XP Pro.

    I checked the internet for a solution, but in the end I had to write a message here.

    Hope for more help.

    > But today when I tried to use it it displays a message this device not recognized and it cannot install the driver for this device.

    If the HARD drive worked perfectly in the past without the use of drivers, then I guess that this has nothing to do with a missing driver.

    In your case I would recommend to check and test the HARD disk on another computer/laptop running a Win XP or Vista.

    If the drive HARD wouldn't connect and would not be functioning with the help of other computers, then a hardware problem is possible

    PS: this external USB hard drives are Plug & Play compatible and so a pilot should not be necessary!

  • 3 50 PX1394U external hard drive not recognized

    I recently bought the external hard drive, Toshiba PX1394U 3 50. I followed the instructions for the installation and everything went as planned either he found material etc. and returned with the message of successful installation.

    However, when I go in my computer that there should be an icon for the external hard drive and it does not exist.

    I saw the thread, recommending using REGEN, but this has no effect on the problem - the icon still does not appear in my computer.

    I use a laptop computer from a different manufacture running Windows XP and all updates are loaded.

    I also had the same problem when loading on my desk.

    Any ideas?

    If you get the message installation was successful, you should find the HARD disk in disk management.
    Control Panel > administrative tools > computer management > disk management

    Maybe you first create a partition or format, but normally you will see players all recognized.
