Recovery Tips

No need to scan completely

If you just want to find the files that were accidentally deleted, no matter which data recovery software you use, or whether it has a quick scan method similar to EasyRecovery, there is actually no need to completely perform a complete hard disk partition where the files were deleted. cluster scan.

Because when a file is deleted, the operating system only marks the file with a deletion mark in the directory structure. Any data recovery software will read the directory structure information before scanning and successfully find it based on the deletion mark. The file was just deleted.

So, you can manually interrupt the cluster scanning process after the data recovery software has finished reading the directory structure information of the partition. The software will still correctly list the information of the deleted files, which can save a lot of scanning. time to quickly find accidentally deleted file data.

Take the NTFS format partition as much as possible

The MFT of the NTFS partition is stored in the form of a file on the hard disk. This is why EasyRecovery and Recover4all scan the NTFS partition even if they use the full scan method. The reason why it is so fast - in fact, they do not actually perform a cluster scan after reading the MFT of NTFS. They just list the file information on the partition based on the MFT information. It is very tricky, thus overwhelming the scanning speed of the NTFS partition. Other software that honestly scans cluster by cluster.

However, the success rate of file recovery for NTFS partitions is almost the same for all software. Facts have proved that this trick is indeed effective, and it also proves that the file security of the NTFS partition system is indeed higher than that of the FAT partition. This is the reason why NTFS partition data recovery is the best in various test results. As long as the MFT information can be read, file data can be recovered almost 100%.

Cleverly set the scanning cluster range

Setting the scanning cluster range is an effective method to speed up the scanning. Advanced custom scanning methods like EasyRecovery, and the default scanning methods of FinalData and File Recovery all allow you to set the cluster range of the scan to shorten the scan time.

Of course, it takes some skills to determine the location of the target file on the hard disk. Here is a simple method, use the fragmentation analysis program in the hard disk defragmentation program that comes with the operating system (be careful not to defragment it) , just use its fragmentation analysis function). After the partition analysis, the program will clearly display the unused space of the hard disk graphically, and then estimate the approximate cluster range of these unused spaces based on the proportion of the graphic. When searching, set only Just search these empty cluster ranges. For large partitions, this can really save a lot of scanning time.

Use file format filters

Friends who have never used data recovery software before may be shocked by the capabilities of the software when they first use it. The purpose may just be to find a few accidentally deleted files, but the software lists hundreds of previously deleted files, making it really troublesome to find the files you really need.

Here we need to use EasyRecovery's unique file format filter function. When scanning, fill in the extension of the file you are looking for in the filter, such as "*.doc", then the software will only display DOC file found; if you are just looking for a file, you even only need to fill in the file name and extension (such as important.doc) in the filter, and the software will naturally find the file you need, which is very fast and convenient.
