PC Inspector File Recovery 4

PC Inspector File Recovery 4 is a data recovery hard drive disaster software, and the best part is, its free to use with no limitation. It recovers files, even when a header entry is no longer available. Competition products cannot recover such files. Screenshot below:

PC Inspector File Recovery (freeware) is a hard disk and driver data recovery program that supports the FAT 12/16/32 and NTFS file systems. It finds for the missing or corrupted partitions automatically, even if the boot sector or FAT has been erased or damaged (does not work with the NTFS file system). With a click of a button, you are able to recover files with the original time and date stamp. Supports the saving of recovered files on network drives.

Easeus Deleted File Data Recovery Software

EASEUS Deleted File Recovery is a fully functional freeware designed to recover deleted files from all types of media such as Hard Disk Drives, Floppy Drives, Smart Media, Compact Flash, Memory Sticks, and other types of removable media.

Unlike PC Inspector File Recovery 4, EASEUS comes with a number of limitations such as not having the ability to recover files from corrupted partitions, corrupted system, compressed and encrypted files and more. EASEUS may not be the best hard drive data recovery software available online, but it does have a much more user friendly interface.

Pandora Hard Drive Data Recovery Tool

Pandora Recovery allows you to find and recover recoverable deleted files from NTFS and FAT-formatted volumes. Pandora Recovery will scan your hard drive and build an index of existing and deleted files and directories (folders) on any logical drive of your computer with supported file format. Once the scanning is complete you have full control over which files to recover and what destination to recover them to.

Pandora Recovery is not free as written in most blogs and websites. It is free to download and install, to make full use of the software (recover files), you have to purchase the full version.

Note:Hope magic will come.Hope the external hardisk will recover~
