Disk Partition

Facing Difficulties or problems to make partitions of HDD ?
        Now it so easy by using JB Disk.

Disk partitioning is the act of dividing a hard disk drive (HDD) into multiple logical storage units referred to as partitions, to treat one physical disk drive as if it were multiple disks, so that a different file system can be used on each partition.

                       A JB Disk software program can be used to create, resize, delete, and manipulate these partitions on the HDD. A partition consists of a range of cylinders of HDD—i.e. each partition is defined by both a start and end cylinder (the size of cylinders varying from disk to disk).

Benefits of multiple partitions

Logical partitions require extended partitions. In Windows, extended partitions can be used to create many logical partitions.

Creating more than one partition has the following advantages:

• Separation of the operating system (OS) and program files from user files. This allows image backups (or clones) to be made of only the operating system and installed software.
• Having a separate area for operating system virtual memory swapping/paging.
• Keeping frequently used programs and data near each other.
• Having cache and log files separate from other files. These can change size dynamically and rapidly, potentially making a file system full.
• Use of multi-boot setups, which allow users to have more than one operating system on a single computer. For example, one could install Linux, BSD, Mac OS X, Microsoft Windows or other operating systems on different partitions of the same HDD and have a choice of booting into any compatible operating system at power-up.
• Protecting or isolating files, to make it easier to recover a corrupted file system or operating system installation. If one partition is corrupted, other file systems may not be affected.
• Raising overall computer performance on systems where smaller file systems are more efficient. For instance, large HDDs with only one NTFS file system typically have a very large sequentially accessed Master File Table (MFT) and it generally takes more time to read this MFT than the smaller MFTs of smaller partitions.
• "Short stroking", which aims to minimize performance-eating head repositioning delays by reducing the number of tracks used per HDD.The basic idea is that you make one partition approx. 20–25% of the total size of the drive. This partition is expected to: occupy the outer tracks of the HDD, and offer more than double the throughput — less than half the access time. If you limit capacity with short stroking, the minimum throughput stays much closer to the maximum. This technique, however, is not related to creating multiple partitions, but generally just creating a partition less than the disk size.
• For example, a 1 TB disk may have an access time of 12 ms at 200 IOPS (at a limited queue depth) with an average throughput of 100 MB/s. When it is partitioned to 100 GB (and the rest left unallocated) access time may be decreased to 6 ms at 300 IOPS (with a bigger queue depth) with an average throughput of 200 MB/s.
• Partitioning for significantly less than the full size available when disk space is not needed can reduce the time for diagnostic tools such as checkdisk to run or for full image backups to run

Partition recovery

When a partition is deleted, its entry is removed from a table and the data is no longer accessible. The data remains on the disk until being overwritten. may be able to locate lost file systems and recreate a partition table which includes entries for these recovered file systems. Some disk utilities may overwrite a number of beginning sectors of a partition they delete
