Hard drive not being recognized

  1. My harddrive works great apart from the fact it has to be plugged in twice in order to be recognised by my PC/PS3, for example, i turn my PS3/PC on with the device connected via USB and it wont be recognised, i unplug the USB then plug it back in and it is recognised straight away, it seems to only happen when the device has been left turned off for any great length of time, when i turn my PS3/PC off and back on again (within 5 mins) the device is recognised no problems. any idea what could be causing this problem and how i can fix it???

    You could try:

    Go to Device Manager:

    Click Start, then right click My Computer, select Manage. Go to Device Manager, then under Disk Drives, right click the External Hard Drive and go to Properties, go to the Power Management tab, then uncheck the option to "Allow the computer to turn off this device to save power"

    However, the computer may turn back on from standby/sleep if the hard drive requires any power at all..
