Copy Bad Disk

CBD (Copy Bad Disk) is a program designed to copy data from damaged or error-prone disks. The software uses advanced methods to read problematic sectors and recover the maximum amount of information possible. It is intended for hard drives, CDs, DVDs, and other storage media with physical or logical failures.

• Safe reading mode. CBD uses non-destructive reading algorithms to minimize stress on the damaged disk. The program performs multiple read attempts on problematic sectors before marking them as unrecoverable.
• Reading parameter configuration. Allows adjustment of reading speed, number of retries, and buffer size. This optimizes the process according to the type of damage on the disk.
• Disk image creation. The software generates image files (ISO, IMG, etc.) containing the recovered data. These images can later be mounted on virtual systems.
• Specific file recovery. CBD can search for and extract individual files without needing to copy the entire disk. It supports common formats such as documents, images, and videos.
• Detailed operation logging. Generates logs with information about damaged sectors, recovered files, and encountered errors. These logs help analyze the disk's condition.
• RAID compatibility. Supports reconstruction of damaged RAID arrays, allowing data recovery from multiple disks configured in this mode.
• Command line interface. Includes a CLI version to automate recovery processes in environments without a graphical interface.
• Support for encrypted disks. Can work with disks protected by basic encryption, provided the password or access key is known.
• Bad sector filtering. Identifies and excludes physically damaged sectors to prevent further data corruption.
• Pre-recovery analysis. Performs a preliminary scan to assess the disk's condition and estimate the chances of success.
• Low speed mode. Reduces the rotation speed on mechanical disks to prevent further deterioration during recovery.
• Support for legacy file systems. Compatible with FAT12, FAT16, FAT32, NTFS, ext2/3/4, and other less common file systems.

CBD was created in 2002 by GoodLuckSoft. The program was developed in C++ with assembly components for critical low-level operations. The first version focused on IDE hard drives, with later support for SATA, SCSI, and USB devices. The development team maintains regular updates to incorporate new storage technologies.
