As often happens, the user can format the partition and start filling it with other data recovery, and only then realize that the old partition contained important information. In such cases, there can be no unequivocal recommendation.
Everything very much depends on how much (quantitatively and in volume) new data was recorded, and also where this data is located. Depending on the conditions, the result can be from 0 to close to 100%. In absentia it is unpredictable.
In many cases with large data area overlap, it makes sense to start with a regular expression search method for the desired file types to see if there is still evidence of the desired data, and if found, search the file system meta data.
In a data recovery lab environment, a specialist will build a map of unallocated space and conduct a regular expression search only in these areas in order to exclude the presence of already existing Facebook data in the search results. Also, with the help of integrity control tools, it will significantly reduce the number of false recognitions.
And in some tasks like recovering jpg files (for example, someone’s home photo album) it will be able to sort according to the information contained in the Exif tags of jpeg files, which will allow you to get a result ordered in chronological order and sorted by camera models.
Crash in procedures for resizing, moving or merging partitions :
In cases of emergency termination of disk manager procedures for resizing a partition, moving it, or merging several partitions, you have to figure out exactly what steps were taken and at what stage the operation was stopped in order to get the best possible result.
Given the complexity and number of possible variations, we will consider only a universal option for a user who needs a result with a minimum number of actions. The entire drive must be selected as the object for analysis to ensure that all data locations are covered.
Use the meta data search method and copy all data variants for the found file systems. There is a high probability that different sets of files will be correct in each of the options. Searching regular expressions for given file types is also important, because in such cases of data loss, partial loss of information about the names and location of files is possible.
