Q1: Why the Recovered Files Cannot be Opened?
The file is saved in two parts on the storage device: directory information (consisting of file name, timestamp and size information, etc.) and data content. If you cannot open a file with the original file name and folder structure, one of the possible reasons is that the directory information is corrupted. You can try Deep Scan to find the deeply buried files.
Q2: Why It Is Not Suggested to Recover the Files Back to the Original Drive?
Any changes on the drive will change or damage the storage structure of the missing files. If you save the recovered files back to the same drive, the original data structure and data content will be destroyed or overwritten, which will result in permanent data loss. Therefore, you should prepare another disk to save the files.
Q3: How to Confirm Whether My Files Can be Recovered or Not Before Purchase?
4DDiG offers free download and free preview. Please download the trial version to scan your drive and check whether your lost/deleted files are found in the scan results. If not, it is not suggested to purchase.
Q4: How Long Does 4DDiG Take to Scan?
This largely depends on the capacity of the hard drive and the performance of the computer. As a reference, in general, for a 1 TB hard drive that works normally, most drive recovery can be completed within 10 to 12 hours.
Q5: Why Some Files Have Random File Names in The Scan Results?
These files without the correct file name or folder structure must be found by Deep Scan, which is very reliable and useful when the directory information of the lost file has been damaged. If you cannot open the recovered files with the correct file name, or you cannot find them by file name or folder structure, please check each file with a random name to retrieve the lost data.
