Recovering Files Manually Using Command Line Tools

In cases where graphical recovery software cannot be used or fails to locate files, command line tools offer a powerful alternative, particularly for advanced users. These tools allow direct interaction with the file system and can sometimes access data that standard software cannot.

For Windows users, the `chkdsk` utility can help repair file system errors that might be preventing access to files. Running it with appropriate parameters can fix logical errors on the external hard drive:

“`bash
chkdsk X: /f /r
“`

Replace `X:` with the drive letter of the external hard drive. The `/f` flag fixes errors, and `/r` locates bad sectors and recovers readable information.

On macOS and Linux, the `fsck` (file system consistency check) command is used to repair file system inconsistencies:

“`bash
sudo fsck /dev/sdX
“`

Replace `/dev/sdX` with the appropriate device identifier.

For file recovery, tools such as `TestDisk` and `PhotoRec` are widely recommended:

  • TestDisk specializes in recovering lost partitions and repairing corrupted file systems.
  • PhotoRec focuses on recovering files based on file signatures, making it useful when the file system is severely damaged.

Both tools run from the command line and support multiple platforms.
