First step you can take is disconnecting hard drive from power, and disconnecting computer (after turning everything off). On laptops also remove main battery. This procedure drains electrostatic charges that may prevent USB devices from being recognized.

Also go to My computer and check if there is a problem with USB in hardware devices.
Before getting desperate about the data, a more definitive test is done connecting the HDD to a different computer.

If the unit is not detected on more of one computer, test first a different USB cable, and check USB connection on both sides (I used to sell WD once, Passport and MyBook have a weak USB connector at the back).

If still no luck, then the disk may be faulty. In that case, first step in data recovery is mounting the internal disk drive into a different enclosure. Enclosure must not necessarily be WD, just ensure that is PATA (IDE) or SATA, depending on the original HDD (I think 250Gb are SATA).

If mounting the disk into different enclosure still does not work, then the disk itself is defective. In that case you can only get data using an expensive facility.

IF the disk is not recognized, the problem is usually either computer or enclosure, not the HDD by the way. Your data are probably still in the HDD.

Here general troubleshooting for Mybook, steps are the same:Test for the MyBook .

    Re:hard drive does not have external power.. it is powered by the usb port

    I know, simply disregard the "disconnect power adapter" in the link.The link referred to bigger brother Mybook, the 3.5 inches. THis is the 2.5 inches and it is powered through the +5V line in USB from computer.

    RE:and it is not 250GB but rather a 750GB

    The only change is that in the 750GB the internal hard drive is for sure a SATA.

    The answer remains the same.

External drive not picked up on computer

External hard drives not only provide additional storage space on a computer system but also allow data to be conveniently transported from one computer to another.

These drives typically plug right in to a port on the computer and function without any additional setup; however, if you are running into trouble where your external hard drive is not being detected, you must troubleshoot the situation to determine why the drive appears to be missing.

Check the USB connection running from the hard drive to your computer.

If the USB cable is not seated securely in the port, the computer will not detect the external drive.

Disconnect the USB cable from the computer and plug it into a different USB port. Occasionally, a USB port will fail to function with some hardware and changing the USB connection may correct this issue.

Switch from a USB to a Firewire cable connection, if possible.

The USB port on the hard drive may have died; if so, changing to a Firewire connection will resolve this issue.

Install the driver for the external device from the installation disc provided with the product. Older computer systems may require you to manually install this driver.

After inserting the installation CD, follow the prompts from the installation wizard to install the driver on your computer.

Restart the computer.

If you connected the external drive while the computer is powered down, it may not recognize the device when you turn on the computer.

After restarting the computer, connect the external drive to the system.

The drive should now be detected by your operating system.

Connect the external hard drive to a power source and then plug it into your PC computer using a USB or Firewire cable.

Log on to your PC computer using an account with administrative privileges.

Open the Start menu and click on the "Control Panel" icon.

Open the "Administrative Tools" folder and then double-click on the "Computer Management" icon.

Select "Disk Management" from the list of options on left side of the window.

Right-click on the drive you want your computer to recognize and select "Change Drive Letter and Paths."

Select a drive letter for the external hard drive to be recognized as and click "OK."

The drive will now appear in My Computer.

Hope this helps.

The drive clicks when plugged in but nothing shows up on the computer.. nor does it seem to light up..

do you have a hard drive and cd in the computer already? if so the drive probably wants to be recognized as either a master or slave in a slot that is already taken by an internal component. you will have to change the jumpers on the internal device or unplug it then turn your computer on and then plug the usb drive in. also are you using a 2.0 usb port? it's not the only kind even though they look alike.

Windows does not recognize the device ?

Hello raigangarkam,

There's a chance that that particular USB slot on your computer may not be working.

You may try to attach another USB device on that port to check if that works or not.

You might also want to try & attach your 2GB Cruzer flash drive on another USB port or another computer & check if it recognizes it.

If it still won't be recognized on the other computer, you might need to replace that 2GB Cruzer USB Flash Drive.

Hope this helps.

My computer stopped recognizing my seagate

same thing happened with me, Looks like your pc usb slot is not providing enough power to the drive wither use a Y - USB cable (comes with three USB ends ; where in you will insert two USB cable ends to two usb ports on your pc and the other to ur hard disk) or buy a powered USB root hub.

Is there a plug in on the board for a SATA input. So I can install another hard drive.

Do these specs sound right?

The Lenovo 3000 J115 series of computers does not come with a video card but with the NVIDIA GF 6100 Integrated Graphics which is plenty to run the Windows Vista operating system. You can also expand the graphics capabilities by adding a video card in the available PCI Express video card slot.

The motherboard, Lenovo Model L-NC51M, which comes with this series of computers, has two memory stick slots, one PCI express x1 slot, one PCI express x16 slot and two PCI slots. The 3000 J115 models come standard with Windows Vista Home Basic Operating System, 512 gigabytes memory, an 80 gigabyte serial ATA hard drive, Integrated Gigabit Ethernet and a 16X DVD optical drive.

If so, there should be more sata ports on the motherboard.

This what sata ports look like:

You also need a sata power cord or Molex to Sata power adapter:

See pictures:

Hope this helps you some.

Try some other USB device (memory-stick, printer, camera) in the USB slot in the Vista computer, just to "prove" that Vista will recognize _any_ USB device connected to that slot.
