What Is Partitioning A Hard Drive?

To divide memory or mass storage into isolated sections, in DOS systems, you can partition a disk so each partition will behave like a separate disk drive. Partitioning is particularly useful if you're running more than one operating system. For example, you might reserve one partition for Windows and another for UNIX.

In addition, partitioning on DOS and Windows machines can improve disk efficiency. This is because the FAT/NTFS system used by these operating systems automatically assigns cluster size based on the disk size: the larger the disk, the larger the cluster. Unfortunately, large clusters can result in wasted disk space, called slack space. There is an entire sector of the software industry devoted to building utilities that let you partition your hard disk, such as Fdisk, Partition Magic, EaseUS Partition Master.

Use partition tools ( such as Fdisk, Partition Magic, EaseUS Partition Master) to repartition hard drives is a common occurrence for using a hard drive, but you need to take care data. Partitioning hard drive into many chunks will erase data if it is done incorrectly or problems exist on the hard disk.

Due to the corruption of the logical disk structure, this can be physical problems (e.g. bad sectors on the hard disk), incorrect software installation etc. Such as Partition Magic in the wrong operation, unexpected termination in resizing partition or program crash due to power error or more problems of the hard disks (e.g. due to bad sectors etc.). Where previously the computer would boot and be usable, systems often refuse to start and may produce the following error messages: (these errors are frequently displayed on a black screen with white text)

Frequently Asked Questions

"Recover lost files, even after deleting a partition or formatting your drive."Macworld

2. Why cannot I recover 2GB data for free?

It is recommended to check the version installed is Free or Trial because they are different versions.

Trial has data preview function but cannot save any files, while the Free version enables to recover 2 GB files. The default free space is 500 MB and you may share the product on social media to get another 1.5 GB.

3. Why cannot the recovered files be opened?

A file is saved as 2 parts on the storage device: directory info (which is comprised by file name, time stamp and size info, etc.) and data content.

If the files with original file names and folder structures cannot be opened, one possible reason is the corrupted directory info. There is still a chance to recover the data content with the RAW Recovery method in our software.

4. Why isn't it suggested to recover the files back to the original drive?

The storage structure of the lost files would be altered or damaged by any changes on the drive. If you save the recovered files back to the same drive, the original data structures and data content would be corrupted or overwritten, which causes permanent data loss. So you should prepare another disk to save the files.

5. How can I check whether my data is recoverable or not before purchase?

The Free version helps you save 2GB files to better verify the recovery quality of our product before purchase.

6. How long does it take to scan the drive?

It strongly depends on the capacity of your hard drive and the performance of your computer. As reference,most drive recoveries can be completed in around 10 to 12 hours for a 1-TB healthy hard drive in general conditions.
