Download and launch the iPhone Data Eraser on the computer first. Then connect iPad to your computer. And the program can automatically detect it .
You will see the window pop up. On the catalogue, "Erase All Data" is proper when history needs deleting.
"High level", "Medium level" and "Low level" are provided for you. "High level" is suitable if you have previously saved any private files like bank records, password etc. on your device. "Low level" can ensure deleted files irrecoverable by overwriting all of them with zeros. "Medium level" is the common choice, which will overwrite the memory space with junk data to ensure that the files are not recoverable.
Click "Erase Now". All data will be completely deleted.
It won't take too much time to clear them all. After the process is finished, iPad works much more quickly, and you do not need to worry about what and when will happen caused by full storage.
iPhone Data Eraser can make your iPad always clean and efficient because it ensures delete history, reminders, photos, caches, contacts, call history, ect. irrecoverable. Thus, I also remind you that the data, deleted by iPhone Data Eraser, is impossibly retrieved, no matter you use what kind of recovery software.
