Cloned hard drive "C" (WD 40GB) to A Deskstar 8oGB using external enclosure. When I remove the old drive and install new drive and boot up I get Msg drive 0 not found retry or enter setup. If I enter setup will BIOS automatically find drive 0 or do I need to do something?

You can still save your information if you remove the actual hard drive from its enclosure.

Simple as opening the enclosure, remove the hard drive then use an external hard drive dock - here

A hard drive dock instructions are here. Youtube: http://www.youtube.com/watch?v=OUrw9W3-FcA

and connect it to your computer for back up to a new hard drive.

A how-to can be found here. Youtube = http://www.youtube.com/watch?v=hQ_vjyvK28A

Let me know if this works.

did you get all the files? most likely there is a corrupt or missing set of files in the cloned files
i suggest you either get a new hard copy (disks) and install from there or use linux (most linux OS's are free online)

How old is your hard drive ? Hard drives eventually fail due to normal usage or it could be something else. You need to provide more information.

The external storage device has several major components:
* USB cable
* external power-supply
* disk-drive inside the enclosure
* USB-to-disk-drive adapter inside the enclosure.
Try a different USB cable.
Try a different USB port on your computer.
Try a USB port on a different computer.
Take a multi-meter, and measure the output voltage/amperage of the power-supply,
and compare with the specifications on the label of the power-supply.
Open the enclosure, and remove the disk-drive, and attach it as a "slave" drive in a desktop computer, to see if bypassing the USB-to-disk-drive adapter bypasses the problem.
Look at the label on the disk-drive, for manufacturer, product-number, serial-number, and manufacture date. Access the manufacturer's web-site, and use "check warranty status" to see if the warranty still is valid. If so, the drive can be replaced, at minimal cost to you.
Buy a new, compatible, disk-drive, and install it in the enclosure, to "revive" your external storage device.
Search online for a professional "data recovery service". For a significant fee, they can repair your disk-drive, just long-enough to copy your files to a new disk-drive.
Note that W.D. has a "Customer Loyalty" program. Buy a new W.D. disk-drive through the W.D. web-site, at a significant discount.

Try connecting it to a different USB port on your computer.

Try connecting it to a different computer.

If the problem persists, either:

* the USB cable is damaged,

* inside the enclosure, the disk-drive is not functioning
(although the lamp indicates that it is getting electrical power)

* inside the enclosure, the USB-to-disk-drive adapter has failed.

If the warranty is still valid, W.D. will replace it, at no cost to you.

If the warranty has expired, W.D. has a "Customer Loyalty" program; buy a new unit from their web-site, and you can get a discount, as a previous customer.

Or, open the enclosure, and remove the disk-drive, and temporarily connect it as a "slave" disk-drive in a desktop computer, to see if it is working at all.

Or, buy a new, compatible, disk-drive, and mount it into the enclosure, to make a "new" external disk-drive.

The problem may not be with the hard drive itself but with the interface between the drive and the USB port. The drives in most cases are fine if they have not been dropped or abused. The problem with external drives is usually the small circuit board that contains the sata to usb interface. Try purchasing another external hard drive enclosure and remove the drive from the enclosure you now have. There are guides on youtube to show you how to take one of those WD enclosures apart. Just install the hard drive in the new enclosure and load the driver files that come with the new enclosure. You should have a working external drive....as long as the hard drive has not failed.

sounds like you're trying to format with FAT 16 or 32 which limits the partition size.
Try formatting with NFS which has no limit on partition sizes

since you said that the HDD works you have nothing nto worry, that means you have installed it correctly. as for clearing it up suggest you do a complete format. when you plug in the USB the pc will assign a drive name to it. note it down. the right click my computer/manage/disk managment(from the left panel) right click on the drive you noted down & format.

Add a letter for this HDD in "control panel\performance and maintenance\administrator tools\computer manager=ment\disk management"

Drag and drop the files from one drive to the other.

1. Plug your new drive in
   
2. Right click 'my computer'
   
3. than open 'C drive'
   
4. repeat steps one and two
   
5. than drag the files from C' drive to new drive'
