Why need to partition hard drive for Windows 7?
If we compare hard drive to a book, a partition (also known as drive or volume) is
one of the pages in a book and data only can be saved on the partition. Sometimes
the hard drives of your pre-install Windows 7 computer have been divided into one or
more partitions by manufacturers. However, the partition layout is not the one you
want it to be. Maybe there is only a single system partition using all the disk
space, while you need other partitions for data storage and backup; Maybe the disk
space allocated to C: drive is not enough; Maybe a certain partition is useless and
you want to delete it; Maybe...; There are too many reasons for partitioning a hard
drive in Windows 7. Usually, partitioning a hard drive in Windows 7 includes resize
partition, create partition, delete partition, format partition and more.

partition. In this example, we introduce the first way. Right click on an
unallocated space and choose "Create Partition" in the drop-down menu.
In the pop-up window, you can label partition, change drive letter and adjust
partition size by dragging slider bar.

- Primary partition is used for setting active; Windows operating systems or
other systems start from primary partition.
- Logical partition, to some extent, it is extended partition.
- File System:
- NTFS, FAT32 and FAT.
- NTFS supersedes the FAT file system as the preferred file system for
Microsoft’s Windows operating systems nowadays.
- FAT32 and FAT are old file systems; they are simple and readable to work on
a large number of operating systems. They can not support the file which is
larger than 4GB.

the cluster size, we suggest you do not change it, click "OK":
Click "Apply" on the toolbar to commit the changes.

and perform disk-related tasks. To open Windows 7 Disk Management, press "Windows+R"
hotkey and type "diskmgmt.msc" in the Run window. And then click "OK"
or hit "Enter".

AOMEI Partition Assistant Vs Windows 7 Disk Management
Compared with AOMEI Partition Assistant, there are lots of restrictions in Windows 7
Extend Volume: you cannot extend a volume even though there is
unallocated space on the disk. Disk Management only allows you to extend a volume to
contiguous unallocated space behind it. If not, the "Extend Volume" will
be greyed out. However, AOMEI Partition Assistant enables you to add
non-contiguous unallocated space to a partition.
Create Partition: if disk style is MBR, you may receive two errors
as below when creating partitions with Disk Management. Howerver, in such case AOMEI
Partition Assistant also can create partitions.
- If the MBR hard disk drive already contains four Primary partitions, you may
receive "The operation you selected will convert the selected basic disk(s)
to dynamic disk(s)".
- If the MBR hard disk drive already contains three Primary partitions and one
Extended partition, you may receive "You cannot create a new volume in this
unallocated space because the disk already contains maximum number of partitions".
Apart from the restrictions metioned above, AOMEI Partition Assistant also brings
some features that Windows 7 Disk Management doesn't have. To view all the
features, please click here.
