Installing the hard disk

Note

Your drive has already been set up in the factory. It will not be necessary to reformat or repartition it.

Caution!

Partitioning or formatting a disk drive deletes data. We assume no responsibility for lost data.

Before you install your hard disk ...

We would like to remind you once again that when installing the new hard disk some programs are used that could cause your data to be irreversibly lost if used incorrectly.

Note

Make a backup of all your data and check that the recovery procedure works.

Partitioning programmes

With Windows® Vista/XP/ Windows® 7 the Windows Disk

Management Tool help program in order to install the hard disk.

You can find the program in the computer management.

With some operating systems you must have administration rights to install a hard disk.

Look under help in Windows for detailed information on using this program.

Partitioning the drive

Partitioning a drive divides the space into different areas which can be accessed as separate logic drives (with letters C:, D:, E: etc.). Read the manual of your operating system to find out how to partition hard drives with your particular system.

Formatting the drive

In order to remove data from the hard disk, the partitions must be formatted.

Caution!

You must be totally sure about which drive letter to enter so that you don't format a drive that contains data you wish to keep.

You can carry out the partitioning using Windows' Explorer (right click on the drive and select format).

Read which formatting options you have in the next section.

Choosing between NTFS, FAT, and FAT32

When you use Windows XP/Vista/Windows ^® 7 and Windows 2000 you can choose between three file systems for disk partitions: NTFS, FAT, and FAT32. Use the information below to compare the file systems. NTFS is the recommended file system for the following reasons:

NTFS is more powerful than FAT or FAT32, and includes features required for hosting Active Directory as well as other important security features. You can use features such as Active Directory and domain-based security only by choosing NTFS as your file system.

It is easy to convert partitions to NTFS. The Setup program makes conversion easy, whether your partitions used FAT, FAT32, or the older version of NTFS. This kind of conversion keeps your files intact (unlike formatting a partition). If you do not need to keep your files intact and you have a FAT or FAT32 partition, it is recommended that you format the partition with NTFS rather than convert from FAT or FAT32. Formatting a partition erases all data on the partition and allows you to start with a clean drive.

Whether a partition is formatted with NTFS or converted using the convert command, NTFS is the better choice of file system. (For more information about Convert.exe, after completing Setup, click Start, click Run, type cmd, and then press ENTER. In the command window, type help convert and then press ENTER.)

In order to maintain access control on files and folders and support limited accounts, you must use NTFS. If you use FAT32, all users will have access to all files on your hard drive, regardless of their account type (administrator, limited, or standard.)

NTFS is the file system that works best with large disks. (The next best file system for large disks is FAT32.)

There is one situation in which you might want to choose FAT or FAT32 as your file system. If it is necessary to have a computer that will sometimes run an earlier version of Windows and other times run Windows XP, you will need to have a FAT or FAT32 partition as the

primary (or startup) partition on the hard disk. Earlier versions of Windows cannot access a partition if it uses the latest version of NTFS. The two exceptions are Windows 2000 and Windows NT 4.0 with Service Pack 4 or later.

For anything other than a situation with multiple operating systems the recommended file system is NTFS.

Important

Once you convert a drive or partition to NTFS, you cannot simply convert it back to FAT or FAT32. You will need to reformat the drive or partition which will erase all data including programs and personal files on the partition.

The following table describes the compatibility of each file system with various operating systems.

NTFS	FAT	FAT32
A computer runningWindows XP / Vista / Windows® 7 or Windows 2000 can access files on an NTFS partition. A computer running Windows NT 4.0 with Service Pack 4 or later might be able to access some files. Other operating systems allow no access.	Access is available through MS-DOS, all versions of Windows, Windows NT, Windows 2000, Windows XP / Vista / Windows® 7, and OS/2.	Access is available only through Windows 95 OSR2, Windows 98, Windows Millennium Edition, Windows 2000, and Windows XP / Vista / Windows® 7.

The following table compares disk and file sizes possible with each file system.

NTFS	FAT	FAT32
Recommended minimum volume size is approximately 10 megabytes (MB). Volumes much larger than 2 terabytes (TB) are possible. Cannot be used on floppy disks.	Volumes from size up to 4 gigabytes (GB). Does not support domains.	Volumes from 512 MB to 2 TB. In Windows XP, you can format a FAT32 volume up to 32 GB only. Does not support domains.
File size limited only by size of volume.	Maximum file size is 2 GB.	Maximum file size is 4 GB.

Deleting hard disks from the system

Depending on the operating system, the external hard disk must be disconnected before it can be deleted. Read how this works in the help files of your operating system.

1. Disconnect the hard disk from the operating system if necessary using the safely remove hardware wizard.
2. Now disconnect all the connection cables from the external hard disk.

Caution!

While accessing the hard disk, the hard disk must not be deleted or turned off. This can lead to data loss.

Customer service

Requirements for optimal performance:

• a stable, virus-free computer
- a correctly installed operating system
• cables correctly attached to the hard disk
- regular execution of the Windows defragmenter and scandisk programs to remove sources of error and increase the system performance.

Defragmenting your hard drive can take some time (several hours even on a fast PC), and you cannot use your PC during this time. It's advised that you leave your PC defragmenting over night. To defragment your drive in Windows XP:

1. Close down all applications and disable your virus scanner if possible. Also switch off any screensavers.
2. Click Start and then Programs->Accessories->System Tools->Disk Defragmenter
3. Select a drive and click Analyze.
4. Defragment if your PC recommends it.

ScanDisk is not present in Windows XP. Instead, use Check Disk. To start Check Disk:

1. Open My Computer, right-click a drive, and then click Properties.

2. On the Tools tab, under Error-checking, click Check Now.

Sometimes Defragmenter or Scandisk works on 10% or 30% of a hard drive and then hangs. This is usually caused by Windows programs running in the background. If this happens you can force Windows not to run automatic background programmes. To run ScanDisk/Defrag successfully:

1. Go to Start->Run and type msconfig in the Open: box.
2. On the General tab, uncheck all items listed under Selective startup (make sure that Selective startup is selected).
3. Hit apply and OK and restart Windows. This starts Windows with only the basics running; this insures nothing will interfere with ScanDisk and Defragmenter.
4. Run ScanDisk and Defrag.
5. Go to Start->Run and type msconfig in the Open: box. Select Normal Startup.
6. Restart Windows.

Troubleshooting

PROBLEM: Windows stops responding when I disconnect the external hard drive.

ANSWER: This may occur because Windows is trying to access a file that is in the external hard drive. Make sure that none of the files on the disk are open when you unplug the drive. Be sure to stop the drive before disconnecting the power or adapter cable to prevent any data loss.

PROBLEM: The drive is not recognized by my computer.

ANSWER: Restart your computer.

PROBLEM: The hard drive does not seem to have as much storage capacity as I allocated.

ANSWER: Check that your operating system and file system support the desired amount.

PROBLEM: ScanDisk reports an unrecoverable error.

ANSWER: The Scandisk program tests drives for errors. If ScanDisk finds a problem and is unable to fix it, there may be a problem with the hard disk
