معمولا کسی این کار رو نمی کنه و از همون یک پارتیشنی که بطور پیش فرض وجود داره استفاده می کنن. من هم تا به حال از منبع موثقی چیزی از اینکه این کار امنیت بیشتری داره نشنیدم. ولی بعضی ها عقیده دارن که این کار باعث میشه که عملکرد هارد سریع تر باشه و امنیت بیشتری داره(از جهت سوختن هارد)
Primary و Logical تفاوتی از نظر کاربرد ندارن. تفاوتشون توی ساختاره. معمولا از Primary استفاده میشه
مقداری که به هر پارتیشن اختصاص میدید کاملا سلیقه ایه. می تونید کل فضا رو به 2 یا 3 قسمت مساوی تقسیم کنید.
اگر تصمیم به پارتیشن بندی گرفتید:
To partition and format the external hard drive with Disk Management, follow the steps below:
To begin, access Disk Management by right-clicking on My Computer and left-click on Manage. The Computer Management screen will open.
If you don’t have My Computer on your desktop, it should be located in your Start Menu. You can also find Computer Management in the Control Panel under Administrative Tools.
When Computer Management opens, it will have two panes. On the left pane, there will be a list of items. Under Storage, click on Disk Management. This will load a right pane with 2 windows on the right side. You may need to maximize the Computer Management window to see all your drives.
In the lower right pane, you should see a graphical list of all available drives or devices. Find the drive listing that corresponds to the drive that you want to partition and format. It typically has a black bar indicating unallocated space.
If there is a blue bar, then the drive has already been partitioned and formatted. Make sure, that if you have data on the drive, you back it up before proceeding. Once you are ready to proceed, right-click on the blue bar and choose Delete Partition... You will get a pop-up window asking you if you really want to delete the partition. Click Yes. The bar should now be black.
Right-click on the black bar to see a menu of available options. Select New Partition...
The Welcome to New Partition Wizard will come up. Click on Next to proceed to the next screen.
Choose Primary Partition and press Next.
This is where you can set a partition on the drive. By default Windows chooses the whole drive so click on Next.
If you would like to create multiple partitions on the drive, you can type in the amount in megabytes you want for the Primary Partition, and it will partition and format only that amount. For example, if you have a 500 GB hard drive and you want to split the drive into two partitions, you could type in 250000 (for 250 GB's) in the Partition size in MB area.
Once you finish formatting this first partition, you will need to go back and follow all these steps again to partition and format the left-over unallocated area of the drive. The next time around, however, you will need to choose Extended Partion when you come to the Select Partition Type window. (Look at previous step.) Remember, to change or add partitions, will destroy any data on the drive. So, be sure to plan out ahead how many and what size partitions you want before creating them.
Choose the drive letter that you want the drive to have. By default Windows will choose the next available drive letter. Then click on Next.
This is the format screen. Make sure that the File System is set to NTFS. In the Volume Label field you can give the drive a name if you want. Check the box that says Perform a Quick Format so that the drive will be formatted quickly. Make sure to leave the Allocation unit size to Default, and then click Next.
This screen gives you a confirmation of all the steps that you just went through. Click on Next.
The listing for the drive (Disk 2 in the picture below) will say Formatting as it formats the drive.
When the drive is done (Disk 2 in the picture below) the bar will be blue and the drive will say Healthy.
