Repartition hard drive on Windows 7
Partitions are created and disk space are allocated while installing Operating System, is it possible to repartition hard drive without reinstalling OS and programs when disk partitions are running out of space? Of course it is possible. Actually, it is very easy to do this if you use a right partitioning tool. However, there is potential data loss risk when resizing disk partition with some unreliable software, so pay attention to data safety.
In this article, I’ll show you how to repartition hard drive in Windows 7 (32 and 64 bit) fast and safely.
Why it’s possible to repartition hard drive
A hard drive is an unit of a disk that is used to save both system and personal files. The files are organized like a chain. Take MBR disk as example: there are parameters of partition entries in Master Boot Record, from where Operating System knows how many partitions in this disk and location of each partition. From DBR of each partition, Operating System knows all the files record in this partition, from the record it knows the name, create date, type and other information of each file. To modify a file, Operating System simply modify the data area of this file, and then update the related record in DBR.
To resize a disk partition, it is much easier if it doesn’t require moving location of this partition. Partition tools just need to modify the size and location related parameters of this drive. But if partition moving is required, it is much more complicated, besides partition related parameters, all files related parameters and data area should be updated, so it costs much longer time if there are large amount of files in the drive.
Pay attention to data safety while repartitioning
No matter the Windows computer is for home or commercial usage, there are precious files that cannot be lost, such as family photos/videos, work documents. The bad truth is that there is potential system damage and data loss risk while repartitioning hard drives. As I said above, all related parameters should be modified correctly, but some software internal error and hardware issue (such as power outage) could cause part of the parameters failed to be modified. If it happens, you cannot boot Windows or lose part of files. So back up and select the reliable disk partition software if you want to repartition hard drive in Windows 7 or other computers.
