How to recover data from a formatted Linux partition.

If a partition is formatted on Linux, data cannot be recovered directly. Formatting erases the metadata of the file system, making files unrecognizable and inaccessible. However, you can try using data recovery tools to attempt to recover formatted data.

Here are some common data recovery tools for Linux:

1. TestDisk is an open-source data recovery tool that can assist you in recovering formatted or deleted partitions, files, and directories. It can be downloaded and installed from the official TestDisk website.
2. PhotoRec, another tool provided by TestDisk, is primarily used for recovering photos and multimedia files. It can search for and restore deleted files on formatted partitions.
3. Scalpel is a file recovery tool designed to help you restore files from formatted file systems. It utilizes a series of file signatures to identify and recover files.
4. First and foremost, it is another widely used data recovery tool that can help you recover files from formatted partitions.

Please be aware that these tools do not guarantee a 100% successful data recovery, as the integrity and availability of the data depend on the specific circumstances during the formatting process. Therefore, it is advisable to back up all important data before using these tools and to avoid formatting partitions whenever possible.
