After formatting, files also can be recovered by data recovery software

To prevent deleted files from being recovered by other people, users may wipe partition files by formatting partitions. However, is it completely deleted from hard disk by formatting partitions? In fact, it is not this case, fomatted files from the partitions still can be recovered by some professional data recovery software like MiniTool Power Data Recovery. Here, this data recovery software is not introduced to maliciously recover other people’s private files, but to help users find lost important files from accidentally formatted partitions. The essence of fomatting partitions is unveiled below to help users understand why MiniTool Power Data Recovery can recover files from fomatted partitions.

Essence of fomatting partition
In daily life, formatting means high-level formatting to partitions. Correspondingly, there is low-level formatting, these two are completely different operations. Here, we only talk about high-level formatting. When users execute high-level formatting to a certain partition, it’s not to simlpely delete all the files from the partition. Actually, high-level formatting has plenty of of functions. It can be said that high-level formatting is operation in allusion to file system. When you use Format command to execute high-level formatting to partitions, mainly tasks includes below items:
1. Logically number the sectors from cylinder specified by each logical drive.
2. Create Dos Boot Record on basic partition.
3. Establish file allocation table on each logical drive.
4. Set up file drictory table and DATA conrresponding to root drictory.
The reason why high-level formatting causes entire files loss from partitions is that it executes initialization operation to DBR, FAT, FDT and DATA accoding to specified file systems. However, the initialization operation never means formatted files in the partition permanently disappear from the disk. During initialization operation, operating system empties file index, which prevents operating system from finding files from the partitions. But it doesn’t mean other software can not find these files. Meanwhile, operating system doesn’t perform any operations to data area, so these lost files caused by formatting are still stored in hard disk partitions. This is the reason why files on partition which has been executed high-level formatting can be recovered.

Data in formatted partition still can be recovered
Currently, there are various data recovery software on the market, many of which are developed by amateur programmers. These data recovery software can only recover lost files caused by deleting and many of them has very sole function so that you can not recover files from formatted partition with them.
