"Recover lost files, even after deleting a partition or formatting your drive." —Macworld
- 2. Why cannot I recover 2GB data for free?
It is recommended to check the version installed is Free or Trial because they are different versions.
Trial has data preview function but cannot save any files, while the Free version enables to recover 2 GB files. The default free space is 500 MB and you may share the product on social media to get another 1.5 GB.
- 3. Why cannot the recovered files be opened?
A file is saved as 2 parts on the storage device: directory info (which is comprised by file name, time stamp and size info, etc.) and data content.
If the files with original file names and folder structures cannot be opened, one possible reason is the corrupted directory info. There is still a chance to recover the data content with the RAW Recovery method in our software.
- 4. Why isn't it suggested to recover the files back to the original drive?
The storage structure of the lost files would be altered or damaged by any changes on the drive. If you save the recovered files back to the same drive, the original data structures and data content would be corrupted or overwritten, which causes permanent data loss. So you should prepare another disk to save the files.
- 5. How can I check whether my data is recoverable or not before purchase?
The Free version helps you save 2GB files, so verify the recovery quality of our product before purchase.
- 6. How long does it take to scan the drive?
It strongly depends on the capacity of your hard drive and the performance of your computer. As reference,most drive recoveries can be completed in around 10 to 12 hours for a 1-TB healthy hard drive in general conditions.
