There are known several partitioning schemes. The most popular of them is the so-called DOS partitioning scheme. It was introduced by IBM and Microsoft to use multiple partitions in the disk subsystems on IBM PC compatible computers. Another popular partitioning scheme is the so-called Logical Disks Model (LDM) that originates from the UNIX mainframe systems. Veritas Executive accommodates a simplified version of LDM to the Windows 2000 operating system. Windows 2000 and XP support two quite different partitioning schemes: the old DOS partitioning scheme and the new Dynamic Disk Management (DDM). The problem is that earlier versions of Windows do not support DDM. In addition, most hard disk utilities do not support it as well.. This operation can be accomplished with the Create Partition Dialog. <h5>Restrictions</h5> 1. Do not use the Create Partition function in order to undelete the last deleted partition. 2. The program cannot create new partitions on Dynamic Disks. The current version of the program supports only hard disks that use the DOS partitioning scheme (in Windows 2000 and XP these disks are named Basic Disks). 3. According to the rules of the DOS partitioning scheme, the following combinations of partitions cannot be created: q Two Extended Partitions on one hard disk q Five or more Primary partitions on one hard disk q If there is an <A class="glossterm" href="javascript:kadovTextPopup(this)" id="HotSpot58442">Extended Partition</A> is a partition type you create only on a basic MBR (Master Boot Record) disk. Extended partition is used if you want to create more than four volumes on a disk, since it may contain multiple logical drives. on the disk, only three Primary partitions are allowed 4. The program allows creating new partitions only within blocks of un-partitioned space. It cannot convert a free space on an existing partition to a new partition. <h5>Startup</h5> In order to start the operation you should take the following steps: 1. Select a block of free space on the Disk Map; 2. Call the Create Partition Dialog to set up the operation. There are several ways to do it: q Select in the Main Menu: Partition > Create Partition. q Call the popup menu for the block of free space (right click of the mouse button) then select the menu item: Create Partition. <h5>Setup</h5> Initially the program suggests some consistent values for all parameters. In most cases, you can just press the Yes button to confirm the operation. <img src="db9_help_en060608Per_web.files/image090.png" width="442px" height="356px" border="0" class="img_whs4"> q Define whether the partition will be Primary, Extended or Logical. You can choose the desired partition type from the pull-down list. As a matter of fact, the available alternatives fundamentally depend on the selected block of free space - within the Logical free space, only Logical partitions can be created; Within the Primary free space, both Primary partitions or the Extended Partition can be created. q Partition Size. Define the size (in Mb) of the new partition. q Free space before. Define the position (in Mb) of the new partition relative to the beginning of the block of free space. q Free space after. Define the amount of trailing free space (in Mb) at the end of the new partition. <table class=NormalTable x-use-null-cells style="border-collapse: collapse; border: none; x-border-left: 1px table-solid; x-border-top: 1px table-solid; x-border-right: 1px table-solid; x-border-bottom: 1px table-solid; border-collapse: separate; border-spacing: 0px; background-color: #33cccc;" bgcolor=#33CCCC cellspacing=0> <tr> <td width="44.6pt" class="whs6"> <img src="db9_help_en060608Per_web.files/image002.png" width="45px" height="45px" border="0" class="img_whs8"></td> <td width="489.6pt" class="whs9"> Partition size and position may also be defined by using the drag-and-drop technique.

From the pull-down list select a file system the newly created partition will be formatted to, otherwise the partition will remain unformatted (so that it will not be ready to use). q <A class="glossterm" href="javascript:kadovTextPopup(this)" id="HotSpot25402">Volume label</A> or Partition Label is a small textual field (up to 11 characters) that is located in the partition's boot sector. This value is used for notification purposes only. It is detectable by any partitioning tool including the DOS FDISK utility. Modern operating systems save it within a file system, e.g. as a special hidden file. Thus it is able to contain a relatively large amount of text in multiple languages.. Enter a label for the selected partition in this textual field. It is an irrelevant parameter usually used for drive identification. q Drive letter assignment. The pull-down list contains vacant drive letters that can be associated with the newly formatted partition. In addition, there is the possibility to make further detailed settings (although the default values will do in most cases). To activate the advance mode, you need to click the More options button at the foot of the dialog page. Depending on the chosen file system, the following options become available: <img src="db9_help_en060608Per_web.files/image091.png" width="234px" height="135px" border="0" class="img_whs10"> q Use OS built-in routine.

All file systems used by Windows organize hard disks based on clusters, which consist of one or more contiguous sectors. The smaller the cluster size, the more efficiently a disk stores information. If no cluster size is specified during formatting, Windows picks defaults based on the size of the volume. These defaults are selected to reduce the amount of space that is lost and the amount of fragmentation on the volume. A cluster is also called an allocation unit.. Define the Cluster Size for the formatted partition with this spinner control. <table class=NormalTable x-use-null-cells style="border-collapse: collapse; border: none; x-border-left: 1px table-solid; x-border-top: 1px table-solid; x-border-right: 1px table-solid; x-border-bottom: 1px table-solid; border-collapse: separate; border-spacing: 0px; background-color: #33cccc;" bgcolor=#33CCCC cellspacing=0> <tr> <td width="44.6pt" class="whs6"> <img src="db9_help_en060608Per_web.files/image002.png" width="45px" height="45px" border="0" class="img_whs8"></td> <td width="489.6pt" class="whs9"> Number of available options depends on the selected file system type.</td></tr> </table> <h5>Result</h5> After the operation is completed you receive a fully functional partition. <h4><a name=Formatting_Partitions></a>Formatting Partitions </h4> Any partition should contain some file system to be used for keeping data. The process of installing a file system is commonly known as formatting. A huge variety of file systems have been developed these days. <h5>Supported File Systems</h5> The program provides the ability to format partitions of the following file systems: - FAT12 & FAT16 - FAT32 - NTFS - Ext2 - Ext3 - Linux Swap v. 2 - HPFS This operation can be accomplished with the Format Partition Dialog. <h5>Startup</h5> In order to start the operation you should take the following steps: 1. Select a partition on the Disk Map; 2. Call the Format Partition Dialog to set up the operation. There are several ways to do it: q Select in the Main Menu: Partition > Format Partition. q Call the popup menu for the selected partition (right click of the mouse button) then select the menu item: Format Partition. <h5>Setup</h5> Initially the program suggests some consistent values for all parameters. In most cases, you can just press the Format button to confirm the operation. <img src="db9_help_en060608Per_web.files/image092.png" width="330px" height="164px" border="0" class="img_whs11"> q File system. From the pull-down list select the desired file system type. In fact, the program displays only those file systems that can correctly be placed to the selected partition, taking its capacity into account. q Volume label. Enter a label for the selected partition in this textual field. It is an irrelevant parameter usually used for drive identification. In addition, there is the possibility to make further detailed settings (although the default values will do in most cases).

Unlike the majority of other utilities (Windows Disk Manager included), the program can not only remove references to the deleted partition from the Partition Table, thus making it unavailable for the operating system, but also enables to irreversibly destroy its data. This feature will guarantee security of your personal information. <h5>Startup</h5> In order to start the operation you should take the following steps: 1. Select a partition on the Disk Map; 2. Call the Delete Partition Dialog to set up the operation. There are several ways to do it: q Select in the Main Menu: Partition > Delete Partition. q Call the popup menu for the selected partition (right click of the mouse button) then select the menu item: Delete Partition. <h5>Setup</h5> Initially the program suggests you just to remove references to the selected partition from the Partition Table. <img src="db9_help_en060608Per_web.files/image094.png" width="362px" height="156px" border="0" class="img_whs13"> q Enter the volume label to confirm deleting. To confirm deletion of the selected partition, enter its Volume Label. The current volume label is displayed above. q Do not ask volume label next time. Mark the option to inhibit confirmation next time you start the dialog. <h5>Result</h5> By default, the operation takes only a fraction of a second. However, the program waits until Windows completes the modification of the disk layout. In case you decide to wipe the on-partition data as well, the operation will take much longer, depending on the set wipe parameters. <h3><a name=Changing_Partition></a>Changing Partition Attributes</h3> This chapter explains how you can change partition attributes (<a href="#_Mark_Partition_Active/Inactive">Active flag</a>, <a href="#_Hide/Unhide_Partition">Hidden flag</a>, <a href="#_Change_Partition_ID">Partition ID</a>, <a href="#_Set_Label_of">Volume Label</a>, etc.). <h4><a name="_Mark_Partition_Active_Inactive"></a>Mark Partition Active/Inactive</h4> The program enables to set an active/inactive flag for primary partitions of a hard disk. By default, an operating system will boot only if its partition is active or bootable. In order to mark a partition active/inactive you should take the following steps: 1. Select a primary partition on the Disk Map. 2. Call the Mark Partition Active/Inactive Dialog to set up the operation. There are several ways to do it: q Select in the Main Menu: Partition > Mark Partition as Active/Inactive. q Call the popup menu for the selected partition (right click of the mouse button) on the Disk Map, then select the menu item: Mark Partition as Active/Inactive. <img src="db9_help_en060608Per_web.files/image095.jpg" width="382px" height="129px" border="0" class="img_whs14"> 3.

By default, an operating system does not mount hidden partitions, thus preventing access to their contents. In order to hide/unhide a partition you should take the following steps: 1. Select a partition on the Disk Map. 2. Call the Hide/Unhide Partition Dialog to set up the operation. There are several ways to do it: q Select in the Main Menu: Partition > Hide/Unhide Partition. q Call the popup menu for the selected partition (right click of the mouse button) on the Disk Map, then select the menu item: Hide/Unhide Partition. 3.

It is stored in the MBR and its value is assigned when the MBR sector is initialized by Microsoft standard disk managing tools, such as Windows Disk Administrator and the FDISK utility. In fact, a hard disk's serial number is not important for most operating systems and software. It is known that Windows NT, 2000 and XP store its value in the database of assigned drive letters. A partition's serial number is stored in its boot sector (in FAT16, FAT32 and NFTS file systems). Its value is assigned when the partition is formatted. It does not play an important role for most operating systems and software as well. parameter. A partition's serial number is saved in the boot sector. Its value is generated while formatting. The program enables to modify the serial number parameter for FAT16, FAT32, HPFS or NTFS partitions without re-formatting. In order to change a serial number you should take the following steps: 1. Select a partition on the Disk Map. 2. Call the Change Partition Serial Number dialog to set up the operation. There are several ways to do it: q Select in the Main Menu: Partition > Modify > Change Serial Number. q On the Explorer Bar: click on the current serial number. 3. Enter a new serial number for the selected partition. It should contain 8 hexadecimal figures (0..9 or A..F). The operation cannot proceed until you enter all 8 symbols. <img src="db9_help_en060608Per_web.files/image098.png" width="329px" height="149px" border="0" class="img_whs18"> 4.
