Partition Data Parser

This Python script allows you to parse a 32-character hex string representing partition data. It extracts and calculates details such as CHS values, partition type, LBA, and the size of the partition in bytes, kilobytes, and megabytes.

Features

• CHS Calculation: Extracts Cylinder, Head, and Sector values for both starting and ending CHS.
• Partition Type Identification: Identifies the partition type based on the provided hex value and matches it with its label.
• LBA and Sector Analysis: Calculates the starting LBA and the total number of sectors.
• Size Calculation: Determines the partition size in bytes, kilobytes, and megabytes.

Usage

To use the script, simply input a 32-character hex string representing the partition data when prompted.

Example

python partition_parser.py

Script Breakdown

• parse_partition_data(partition_hex): Main function that takes a 32-character hex string and parses it into meaningful partition data.
• hex_to_binary(hex_string): Converts a hex string to its binary equivalent.
• hex_to_little_endian(hex_string): Converts a hex string to little-endian format.
• binary_to_decimal(binary_string): Converts a binary string to its decimal equivalent.
• get_partition_type_label(partition_type_hex): Matches the partition type hex value with a descriptive label.
• calculate_partition_size(num_sectors): Calculates partition size in bytes, KB, and MB.

Output

The script will output the following information:

Bootable Flag: 80
Partition Type (Hex): 07
Partition Type (Label): Installable file systems: HPFS or NTFS. Also, QNX and Advanced Unix.
Start CHS:
    Cylinder: 0
    Head: 32
    Sector: 33
End CHS:
    Cylinder: 188
    Head: 130
    Sector: 18
LBA Start: 2048
Number of Sectors: 716800
Size in Bytes: 367001600
Size in KB: 358400
Size in MB: 350

Notes

Ensure that the input hex string is exactly 32 characters long. The partition type identification is based on standard partition type codes.
