How to Get Back Lost Files with Raw Recovery
What’s raw recovery?
Generally speaking, raw recovery refers to deep scan, which can help to find lost files or rescue corrupted partitions that deleted recovery and formatted recovery can’t achieve. It reads all sectors on the disk looking for specific file header signatures, to recover the small files stored in one cluster or larger files stored in consecutive clusters on the disk. Besides, it can effectively repair the present fragmentation on the partition before completely corrupted.
When use raw recovery?
Raw recovery is stronger than deleted and formatted recovery. But raw recovery should be used as the last resort to recover data from severely corrupted partitions. If you can’t get back your lost files with deleted recovery and formatted recovery, or your don’t remember how your important files lost, you are supposed to adopt raw data recovery. Deleted recovery and formatted recovery are designed to scan lost files targeting the given scope, which can execute recovering task exactly in short time. While raw file recovery has no limitation for the scan, which would take much more time to finish the work. And it’s not so easy for you to pick out the file that you want to recovery among tons of files in the scanning result.
How to get back lost files with raw recovery?
First, you should have a raw recovery tool installed on your computer. Spotmau PowerSuite Golden is such a tool, which can rescue almost all the data under any conditions, even when your disk/partition crashed.
Note: Never install it on the drive from which you want to recover data, also never save any data on the same drive from which you are recovering data.
Step1. Select raw recovery
Run PowerSuite on your computer, go to “Data Recovery Kit”, and enter “Raw Recovery”. This raw recovery tool allows you to scan severely corrupted partitions for files using a file signature search algorithm, helping you rescue files from a partition with damaged directory structures. Over 290 popular file signatures are available for scanning for your file data in this tool.
Step2. Select partition and file type
Select the partition for raw recovery. Before scanning, you can select the “File Types” button to set the raw recovery scan. This option can help you select the file types to rescue and custom file signatures, which could make your scanning target more accurate.
Step3. Raw data recovery
When the scan finishes, the files you set to scan will be displayed in the results. Due to the large amount of files, you can use the “Filter” to set the file’s size or formatted date to exclude those files you don’t want.
This PowerSuite also offers Deleted Recovery and Formatted Recovery, so before you perform the Raw Recovery, make sure that you have tried them first. The Raw Recovery tool should be used as a last resort in rescuing data from severely corrupted partitions. This tool will read all sectors on the disk sequentially (sector-by-sector) looking for specific file header signatures. The Raw Recovery tool will typically rescue small files that are stored in one cluster or larger files stored in consecutive clusters on the disk, and the degree of fragmentation present on the partition before the corruption occurred will compromise the effectiveness of the tool. Fragmentation occurs naturally when you use a disk frequently to create, delete and to modify files. If you have recently run a disk defragmenter utility on your partition, your chances of rescue are much improved.
