It is inevitable for all users that data is ever lost on our computer, not because of users who accidentally deleted them, but because the partition of the hard drive that contains them is damaged or corrupted.
But before you despair at all for losing so much information, you should try this SoftAmbulance Partition Doctor, which through a new recovery algorithm allows you to recover entire partitions from damaged hard drives, thus restoring all the files and folders they contain.
SoftAmbulance Partition Doctor allows you to recover all kinds of files (supports up to 300 different file formats), being able to work on hard drives of NTFS, FAT, MFT and MBR systems.
Although sometimes it will be totally unfeasible the total recovery of a partition (for being excessively damaged or corrupt), it does manage to recover very large percentages of the total.
You can free download SoftAmbulance Partition Doctor 32, 64 bit and safe install the latest trial or new full version for Windows 10 from the official site.
