Recently I often receive calls requiring about method to unformat external hard drive or solution for data loss in external hard drive.

Method to unformat external hard drive
Before I introduced the method to unformat external hard drive to Robin, I told him to pay attention to several points.
He mentioned that he forgot to backup a crucial folder in the external hard drive. The first lesson he should walk away from the experience is simple: backup, about which I mean regular, periodic backup and backup data to a stable external hard drive.
Second, before calling me for the method to unformat the external hard drive, he tried to use one-key-restore to recover data from the external hard drive. I told him that one-key-restore is used to restore data in system partition, but not used to recover data from external hard drive. And do not try to format hard drive and restore system partition so easily.
I also told him some knowledge about format. Quick format simply erases the hard disk's root directory, twiddles a couple of other things, and you're done. Note that it did not actually go out and overwrite files. Normal format actually goes out and overwrites all of the data on the disk. You'll know you're performing a normal format as it takes a long time.

What we need is just unformat software, and normal "undelete" utilities will probably not work. Here professional unformat software EaseUS Data Recovery Wizard is what we need.
