After installed external hard disk enclosure and plug in the USB port on your computer, the computer will properly identify external hard disk, because there is no partition on the new hard drive, you can not see the drive letter of it in “My Computer”. The following is how to partition the external hard disk.
1. The best operating system is Windows XP, or Win 2000(like XP),Win 98 and Win ME have no such partition method. Right click “My Computer” icon on the desktop, select “management.”
2. In the “Computer Management” window, select “Disk Management.”
3. The new disk will be out of a “initialize disk” window, tick the little box in front of the disk to confirm the completion.
4. Then we can see a 37.25G “Disk 1″ (not assigned), which is not partition.
5. Disk partition including the primary partition, extended partition, logical partition. Right click the diagram on the disk which is not assigned to and select “New Partition.”
6. The disk partition wizard will appear, the next step.
7. Our first step should be into “master disk partition.” The next step.
8. The primary partition size can be arbitrarily specified, if you are only prepared to sub-district 40G hard disk to one partition, all the capacity can be designated as the primary disk partition. Here we are ready to split two areas, the first half of the total sub-district is about 19,000. Next.
9. Directly to the next step without modification (in this step someone select the second entry but does not assign a drive letter, the result is disk are divided, but the drive letter can not be seen, they think  that the external hard disk has problem).
10. Formatting, in this step you can choose FAT32 or NTFS, but if you choose the NTFS, WIN98 and WINME is not supported, you will not see external hard disk drive; If you have an area larger than 32G , you can only select NTFS formatted. In order to complete the partition as soon as possible, it is recommended choose “perform a quick format”, otherwise we have to wait a long time. Next step
11. OK to finish.
12. Is being formatted. If your computer USB is USB2.0 and the previous step to choose a quick format, format will be quickly concluded; if your older computer do not support USB2.0 or do not select quick format, you have to wait a long time.
13. After the primary partition formatting is complete, we need to partition the remaining. In the remaining black bar right click “New Partition.”
14. Now we partition extended partition. Next.
15. It’s not need change capacity, because the rest should be retained by the extended partition (no matter how much) in addition to which the primary partition has been divided. The next step until finished (extended partition is not formatted).
16. We could see extended partition become into a green note, now we partition the logical partition. In the extended partition, right click select “New Logical Drive.”
17. There can only choose a logical drive. you need to partition the capacity of extended partitions to several logical partition, then repeat this step to build several logical drives. The next step you could follow the above described.
18. Logical drive is blue color, when opening “My Computer”, you will be able to see the drive letter, then you could use it to copy something.
The above is external hard disk partition we have completed.
