My external Harddrive just up and stopped showing up on the computer. I mean the lights (red and blue) are on, it just doesnt show up. i even plugged both cables into my comp, and still nothing. I noticed...


First make sure usb cable connected to harddrive is working fine. try it in different usb ports. Press windows key +R key so you can see run then type in run "devmgmt.msc" then press ok so you can see device manager uninstall all usb drivers then it automatic install usb drivers. then check. Also you need to change registry for that type in run "regedit" then press ok then you can see registry editor then locate below key. HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11 CE-BFC1-08002BE10318} And remove upper filter and lower filter.Then restart computer then check. Try your harddrive in different computer if it is not recognized on another computer too then power adapter of harddisk or your harddrive has internal issue.

Most USB hard drives require an external (or secondary) power cable to power the devices when connected to laptop or netbook computers. In some cases, even older desktop computer models will require a similar cable.
This is due to the specifications for the USB standard as it dictates the amount of voltage that a USB port can deliver. Some USB ports are considered "powered" and are sometimes identified by the USB logo and a small "+" sign to indicate the added voltage.
Note: Not all manufacturers use this logo, so if your computer doesn't have this variation of the logo, it doesn't necessarily mean the USB port is not powered.
This added voltage supplies additional current to power smaller devices, such as portable (or 2.5") USB hard drives. However, in the even that the USB port is not powered, then only the minimum amount of current is supplied. This should be enough to slightly power the drive, but not sustain it, thus causing the clicking noise and there isn't enough current running through to move the arm that reads the data on the hard drive.
Chances are that the USB ports on your Asus Eee are not powered and won't allow your hard drive to run until either a secondary cable is purchased or if you use a powered USB hub instead.
The secondary cable looks a lot like a Y-USB cable with one end that connects to your hard drive and the other end consisting of 2 USB plugs that both connect to existing USB ports on your netbook. Between the 2 USB ports, they can draw enough current to power the hard drive - the downside being that if you only have 1 USB port you cannot utilize the cable or if you have 2, they will both be occupying the ports while the hard drive is in use. These cables can cost about $1-7 depending on brand and can be found online in retailers such as eBay & CompUSA.
The USB powered Hub is a more expensive solution, ranging at about $10-25, but is the higher recommended of the 2 solutions since it will provide its own power supply to the tiny device, will use on 1 of your USB ports and since it's a hub, they usually have anywhere from 3-5 additional USB ports (all powered) for you to use, if needed. Some even include built-in memory card readers and they do not require any additional drivers or software to install and can work on any desktop/laptop/netbook.

ASUS P4SDX USB Ports not recognized as USB2 HS Ports


The message comes up when a USB 2 device is connected to a slower USB 1 or 1.1 port. It is only to advise you that the devise will operate faster on a USB 2 port. If your computer has only USB 1 or 1.1 ports, you will always see the message. You can buy and install a card with USB 2 ports and install it. It will come with the USB 2 drivers. Install the card and the drivers and then connect your USB 2 device to the new hardware and you should not see the message anymore.

Good luck, And let me know ho it works out for you.

Does the HDD spinup?
My slightly educated guess... the Ext 2.5in HDD requires more power than it is getting from the single port.

1. Try another port
2. Try it on another computer (all USB ports do not provide 250ma to a load)You may be sharing this avail voltage with all plugged in devices and will have to pull 1-2 others to get the HDD online. Since STARTUP current is high, the HDD pulls all it can from the ports (logical) then settles down and uses 1/3 to keep spinning. After the HDD is up and online, try plugging the other USB devices back in, 1 at a time. If it stalls the HDD - you know the why
3. Take it back and find something a bit less power-hungry (Like Hitichi or Toshiba)

Either the device is bad, the pc port is bad, or the software is faulty. Try connecting to different usb port, then a usb port on a different pc with a compatible os. If still not recognized, then there is physical damage to player.

Try this: disconnect the player from the computer, turn it off, hold in the volume + button, and reconnect the player to the computer while holding the volume + button in. Keep holding the volume + button for an additional 5-50 seconds. Windows should eventually go into recovery mode and revive the player- it will pop up a window that says Found New Hardware Wizard.
