Missing drive when plugged in

If you are inserting the USB into a PC and it does not automatically recognize it go to "My Computer" then look for it there under "Devices with removable storage"
Click on the device and that should allow you to access you have on that USB.
If you are installing hardware with a USB connection, then you may have to go to the "Control Panel" then look for "Hardware and Sound" then "Devices and Printers" and then you can either install the device or the printer from there if you have the software for it.

1. Run Registry Editor (regedit).
2. Navigate to the following registry key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\UsbStor
   
3. In the right pane, double click on the Start value name.
4. Change the value data to 4 to disable the removable USB mass storage device drive access
5. 5.
   
6. To revert and re-enable the drive access for removable USB mass storage device driver, change back the value data for Start to its original default of 3.

The change will take effect immediately to block any USB mass storage device such as USB flash drive, USB key and portable harddisk from been used in the system, while still allowing hardware components to work properly via USB connection. The hack works in most Windows operating system such as Windows Vista, XP, Windows Server 2008, 2003 and 2000.
For user who dare not to modify the registry manually, simply download the following registration entries file to enable or disable the USB drive. Extract the downloaded content in .ZIP format, and then double click on the .REG file to open and apply or merge the registry values to system.

You shouldn't need a driver for windows 7, once you plug in the device it your computer should recognize it as a USB Mass Storage device just like it would with a USB flash drive which can be accessed by going to my My Computer then double clicking the icon for the USB Mass Storage Device.

> functioning properly

Means only that the plug-and-play hardware has been recognized, and that the correct device-drivers have been loaded. It says _nothing_ about the physical condition of the Maxtor.


An external storage-device has four major components:

* the USB cable

* the power-adapter

* the disk-drive inside the enclosure

* the USB-to-disk-drive adapter inside the enclosure.

One of these components has failed.

Try a different USB cable.

Try connecting to a different USB port on your computer.

Try connecting to a USB port on a different computer.

Take a "multi-meter" and measure both the voltage and amperage output from the AC adapter, and compare with the specifications on the label on the adapter.

Open the enclosure, and remove the disk-drive, and then connect it as a "slave" disk-drive in a desktop computer, to see if it works at all.

Purchase a new, compatible, disk-drive, and install it in the enclosure, to "revive" your external storage device.

Get the part-number and serial-number from the label on your disk-drive, and access the manufacturer's web-site, and use "check warranty status", to see if they will replace the device, at minimal cost to you.

There exist commercial "data recovery" services that can try to repair your device, just long-enough to rescue and copy your files. For example, see: https://services.seagate.com/index.aspx?lng=en-US for a "no data - no charge" guarantee.

The problem most likely is the Dell does not recognize the MAC file format (HPFS), but the MAC will recognize the PC's FAT 32 file system.
First format the USB mass storage device using the Dell, format this device in FAT 32 not in NTFS because the MAC can read and write/copy PC format files but the Dell/PC cannot read MAC format files.
Then Safely remove this device, connect it to the MAC and copy the files onto this drive. When you connect this device to the Dell, you will be able to see the files.
Have fun.

Dear Sir,madam

Hello

A few questions that may confirm problem.
Does your computer seem to know that something is plugged in?
Or does it say that it does not recognize the device?

Well, if the computer actually knows that a device has been plugged in, but you just cannot see the device in my computer, here is how you fix that. Just follow these steps:
Control panel
Administrative tools
Computer management
Storage
Disc management

Now you should see your device presented in the schematic below.
Right click on the device and assign a new drive letter.

If your computer states that it does not recognize the device, try plugging it in one of the back USB ports of the computer. Please rate this.

Best regards

What kind of software are you looking for? This should be automatically recognized by Vista as an external storage device. If it is not recognized and you cannot see/use the device; you need a driver to allow vista to talk with your USB device. Are you looking for backup software? Please clarify.

The problem is just with EXTERNAL.
Hdd is fine...Just change the external or buy new
