Your drive does not have a file system installed - you need to use Partition Magic to add a file system or reformat for NTFS or FAT32

Install a My Book External Hard Drive

Installing a My Book external hard drive will add additional hard drive storage to your computer. The My Book external hard drive is easy to install and can be moved between computers so that you always have your information at your fingertips.
If you are thinking about an external hard drive, the My Book is a great choice because of how easy it is to install and transport, if necessary.

Meet the requirements for using the My Book external hard drive on your computer.
It is adaptable with Windows Vista, XP and 2000. For a Mac, it is adaptable with Mac OS X 10.4.8 or later.
Take the external hard drive out of the box and inspect it.
It should be in good condition with no flaws in the exterior.
Plug the AC adapter into an outlet. Connect the other end into the external drive.

Plug in the USB connection to the My Book external hard drive on the back in the USB port.
Plug in the other end of the USB connection to the open USB port on your laptop or desktop.
The computer will recognize the My Book hard drive right away.

Access the hard drive by clicking the "Start" button at the bottom of your screen.
When the window opens, click on "My Computer."
Under "Devices With Removal Storage" you will see the external hard drive.
Double-click the icon to open a window to display any contents stored on this hard drive.

Access an Inaccessible Drive

You can gain access to a working hard drive that is inaccessible when the system starts and assign it a drive letter under the Windows Explorer interface.
Or, you can import foreign disks into Windows or create a partition and format them.
You can scan a drive for bad sectors or lost clusters and repair the system files to allow access to a corrupted drive.
In short, you can utilize the drives as they were intended to be used by completing some operating-system configuration steps that are occasionally required for some drive installations.

Click "Start" (the Windows Orb) and "Computer" to access the Windows Explorer screen. Right-click on the inaccessible drive and choose "Properties" from the context menu.
Click the "Tools" tab and click "Check Now" under the Error-Checking section.
Select both check boxes to allow the system to automatically fix file-system errors and to scan for and attempt recovery of bad sectors.
Allow the system to run the scan the next time the system is booted.
Restart the computer to complete the scan and check for access after the scan completes.
Click "Start" (Windows Orb) and "Computer" to access the Windows Explorer screen.
Right-click on the inaccessible drive and choose "Properties" from the context menu.
Click the "Security" tab and click "Edit" to change permissions for the drive.
Click "Users" from the Group or User Names section.
Check the "Allow" box for full control and check for access after the settings are saved.
Click "Start" and "Control Panel" and then click "Administrative Tools" and double-click "Computer Management" to launch the utility.
Click "Disk Management" to display a list of all detected drives in the system.
Right-click in the left column of the inaccessible drive and click "Import Foreign Disk" to allow the system to convert the disk signature to a local disk.
Check for access after the settings are saved.
Click "Start" and "Control Panel" and then click "Administrative Tools" and double-click "Computer Management" to launch the utility.
Click "Disk Management" to display a list of all detected drives in the system.
Right-click in the right column of the inaccessible disk and choose "Change Drive Letters and Path."
If no letter exists, click "Add" and assign a drive letter from the list of available letters.
If a drive letter is listed, click "Change" and select a new letter to eliminate any conflicts with other devices in the system.
Check for access after these settings are in place, which may require a restart of the system.
Click "Start" and "Control Panel" and then click "Administrative Tools" and double-click "Computer Management" to launch the utility. Click "Disk Management" to display a list of all detected drives in the system. Right-click in the right column of the inaccessible disk and choose "New Simple Volume" to create a partition and format it for use.
Click "Next" when the New Simple Volume Wizard appears.
Click "Next" to accept the maximum size for the drive.
Click "Next" to accept the suggested drive letter assignment.
Click "Next" to format the volume with the suggested defaults or change them if desired.
Click "Finish" to format the drive and make it accessible to the operating system.
Restore a Drive That Is Not Accessible
Microsoft Windows operating systems support a large number of file system formats including FAT12, FAT16, FAT32 and NTFS.
Hard drives are typically formatted with either FAT32 or NTFS, both of which can be used for years without issues.
Damage can occur to the file system through a sudden power outage, malicious software or lack of maintenance, rendering the drive unreadable or inaccessible.
Run the Chkdsk utility in Windows to resolve file system corruption and restore access to the hard drive.

Select the "Start" or "Globe" button and then click "Programs." Click "Accessories" and then right-click the command line icon in the menu that appears.
Click "Run as Administrator" in the drop down menu that appears.
The command prompt will display.
Enter "chkdsk C: /F" substituting the "C:" with the letter assigned to the drive that cannot be accessed, and then tap the "Enter" key.
Enter "Y" and tap the "Enter" key if a message appears that states "Would you like to schedule this volume to be checked the next time the system restarts? (Y/N)."
Let the disk scan run and fix the drive, or if the scan does not start, reboot and let the scan run and repair the drive.
Enable Drive Letter View

Click the "Start" button and choose "Control Panel" from the start menu.
Click "Folder Options" and navigate to the "View" tab.
Scroll down and place a mark next to "Show drive letters," then click "OK."

Configuring Drive Manager

Click the "Start" button to launch the start menu.
Right-click "Computer" and choose "Manage" from the menu.
Click "Storage" in the menu on the right side to extend the section.
Click "Disk Management" under the "Storage" header.
This will show you a list of drives and removable storage on your computer.
It will also report the status of the drives, such as "Healthy."
If the removable storage does not have a drive letter or has a drive letter in conflict with another drive, you can assign it a new letter.
Right-click the icon of your removable storage drive and click "Change Drive Letter and Paths."
Click the "Change" button, then choose a drive letter from the drop-down menu.
Select a letter that is near to the end of the alphabet to prevent drive overlap issues.
Click "OK" to allow the changes to take place.
You should now see the removable storage listed with your other drives on the "My Computer" screen.

My maxtor ATA/133 hard disk is not working with my lapto, it has external usb power supply powered. and version maxtor 3.5 series, fireball 3

Try to open the external enclose and replace the hard drive, if that also does not work then open your start menu, right click on computer and click the "manage" button.
A management screen will appear and close to the bottom you will find disk management.
In disk management locate your hard drive in the list and right click on it and New Partition should appear (or enable) I cant remember it's been awhile since I've done it.
Enable it as a Master Boot Record (MBR) and use the entire volume. This hsould populate it in the list and give it a drive letter.
Also you can try plugging it into another computer, if it works with the otehr computer it could just be a drive letter issue in which you go into Disk Management, right click on the drive, click change drive letter and select a new, unused letter.

Hi there i hav ea maxtor onetouch 4 mini 120 gb.

Remove the hard drive from the Maxtor case, purchase an USB hard drive adapter case, and install the hard drive inside this case. Then you can connect this to the computer's USB port and if the hard drive is OK then this computer will detect it as an external USB hard drive, then you can open the folders and files and back them up.

I have a Maxtor Storage 360 GB Hard Drive. Recently, I disconnected it from my computer. When I reconnected the external drive my computer, at first would not recognize it. Now, it shows up as drive F, but...

Depending on what peripherals you have, each time you you plug a drive in, it may be assigned a different drive letter. You can get a conflict going on there from what it once was and what it now is. You can change the drive letter to one of your choosing however in the "control panel". Try accessing different drive letters to see if your data isn't under another letter first.

Vista is not picking up my maxtor harddriver but wheni had xp was .

Check the disk management MMC - it's likely that you have another drive letter that is conflicting with the Maxtor.
1. Right Click on the Computer Icon (or in the menu),
2. click on Managment,
3. look for Disk Management(on the left side) and click on that.
4. This will show you all the installed HD's that you have.

Your main HD is probably called Disk 0. IF there are any other HD's listed they will probably be labled "removeable", if it doesn't have a drive letter assigned to it do the following:

1. Right click on the Disk (X) that does not have a drive letter. (it should be a "Removable Drive")
2. Select Change drive letter and Paths.
3. Choose a drive letter from the list that is not used, I suggest W or Z just to be sure.
4. After you do that it should come up in My Computer as an available drive.

IF the External Drive is not listed then you need to change the USB port or try it on another PC to see if it works there.

Maxtor 200 gb external will not show up in my computer after numerous installs

For Vista you don't need any driver for this, it should recognize and install automatically.
Did you check the device manager to see if the disk is recognized in the device list?

Next step is to check the Disk Manager (right-click My Computer, select Manage and then select disk management), and see if the disk already has a partition and has been formatted. If not, then it will not show up in "My Computer" with a drive letter yet.

Some details on external hard disk troubleshooting might also help.

Unable to see the 250Gb external drive shown on 'my computer' when plugged in

Hi - thanks for your quick response, much appreciated .........I will try again to explain!!

We have purchased a 250Gb Maxtor portable hard drive which I was told was plug and play. We have followed the instructions for connection but no drive letter is showing up and the external drive is lit up and making a constant beeping noise. The computer doesn't seem to be recognising that an external drive has been connected.
To test our computer out I have connected an 8Gb memory stick to the processor and it shows up as drive H immediately.
FYI - we have XP running on our machine.
Hope you can help!! Thanks
