  1. I have 2 hard drives one 250gb Seagate and one 500gb lacie

    as of yesturday they were both woking fine however i woke up this morning and niether one of them is recognized by the computer. I go to the hardware administation and it just says they are unknown devices without the yellow question mark. any ideas on how to fix this?

    I´ve tried going back to the last restore point but it didnt work. Aswell as i am typing this up I have a little ballon poping up every about 5 sec telling me that one of the devices has had a problem and windows cant recognize it.


    Any ideas?

    Just plug the Master HardDrive in and remove the Slave and any CD/DVD drive

    Note: sometimes just unplugging the drives, and the system power cord out.
    Then holding in the ON switch for 30secs (dispersing all internal voltage)
    Then replugging in the drives and power cord will work.

    forgot to say somehting

    Both of these drvies are external drives(USB 2.0). Not the internal one. The internal one is just fine oddly enough.

    Also when I sart up the computer and look into the BIOS it recognizes them as hard drives. So I think I have narrowed it down to it being a windows problem.

    Another small note, when I first went to re-plug in my seagate drive, windows read it but gave me and error saying more or less that windows could not read / write to file f:/$(some random letters i cant remember) could this be the problem

    maybe a problem with the usb's, try plugging them in to a differant port. just a thought but im new to building computers so may not work.

    I´ve tried all my USB ports, I have six. But the thing is it was working 2 days ago perfectly. To me its a bit crazy for it not to work.

    USB ports seem to be the most sensitive areas of computers, and usually the first to show signs of hardware faults.

    But I believe this may still be likely to do with software (Drivers and settings)

    One option would be to go into Device Manager (Start->Run-> devmgmt.msc) expand the USB device setting and then remove them all (note: any USB devices attached to your computer, including a usb mouse, will stop working)
    Restart the computer and allow all the USB found devices to install
    Then plug the external USB Hard Drive back in (using the back USB plugs on Desktops)

    I tired what you said. It didnt work. I tried even a camera. Could it be some type of virus blocking my USB ports from reading correcly? Or do you think the USB ports are dead?

    You need to confirm all manufacture drivers are up to date
    Possibly repair Windows
    Run CMOS defaults
    And lastly re-install Windows, before confirming it may be hardware related

    Oh, and do all the Antivirus and spyware scans, with updated definitions

    That's the idea, give all the options one (or two!) are bound to work.

    Thanks for the update.
