Hard drive integer partition calculator

Hard disk integer partition calculator guarantees integer partitions and helps you calculate the input size when partitioning. Supports ntfs and fat32
​

How to use

1. For FAT32 partition, 4 bytes are used for every 1024 bytes of available capacity to store information such as disk structure and data storage location, but the first GB of available capacity in the partition does not occupy additional storage capacity, so the hard disk integer partition calculation The formula for FAT32 integer partitioning is:

The number of MB that should be allocated = (the number of GB in the partition - 1) × 4 + 1024 × the number of GB in the partition

2. The hard disk integer partition calculator has a more complicated principle for NTFS partitions. The minimum capacity unit of an NTFS partition cannot be precise to 1MB, but the cylinder size. Hard drives generally have 255 heads and 63 sectors, so the size of each cylinder is: 512bitx255x63=8225280bit=7.84423828125MB

If you want to divide 10GB, it should be 10x1024MB=10240MB

The actual number of cylinders required is 10240÷7.84423828125=1305.4

Cylinders can only be counted as integers, that is, 1306 cylinders

In this way, the actual number of MB should be divided into 1306×7.84423828125=10244.575MB

Regardless of the number of decimal places, add 1, which is 10245MB, so that the system can recognize it as 10.0GB.
