整理磁盘碎片(Defragment your hard disk)

Defragment your hard disk
Before creating new partitions on your hard drive, you shoulddefragment the drive so that all data is stored at the beginning of theexisting partition. Here is how to do it:
Start up Windows.
First, backup your files to CD-ROM, DVD, or an external hard drive.Also remember to backup your Internet link collection (Favourites) andyour e-mails. If your data is encrypted, it is advisable to decrypt itbefore backing it up. This protects you from data loss becausemodifying hard drive partitions always carries the risk of data loss.
Next, start the Disk Defragmenter program under Windows. The programis located at "Start | All Programs | Utilities | System Programs |Disk Defragmenter". Select hard drive c:\ and click the "Check" button.



Click the "Defragment" button. Depending on the size of thepartition and the amount of data on it, this process can take a longtime (over an hour). If you have very large amounts of data, you canspeed up this process drastically by deleting your files after you havebacked them up (see the previous item) and restoring them once you aredone with the modifications. In this case, please make sure beforehandthat your backup is readable, otherwise there will be wailing andgnashing of teeth.

Click the "Close" button.

There is now space on the harddisk for additional partitions.
Shut down Windows.
