What do you mean by a zeroed hard drive?
Zeroing a hard disk drive is a process to permanently erase all data from the hard disk (i.e. formatting the hard drive). This technique involves overwriting of data with zeroes on that drive. Writing zero “0” to a hard drive location causes the magnetization power of that particular spot on the hard drive to be almost zero. (But not exactly 0. It might be around 0.0001). This minute value of the magnetic disk goes undetected by the general hard disk drive software as it is only equipped to decide if the value is closer to high or low i.e. 0 or 1. So the normal hard disk drive software reads 0.0001 as 0 itself as it is close enough to 0 and hence the data is said to be permanently deleted on that drive.
So, can data from a zeroed drive be recovered?
Technically, normal hard disk drive softwares are unable to detect or read any data from a zeroed drive. The data is almost irrecoverable because it has been overwriiten many times using data shredding patterns.
Remo Recover tool is a powerful and efficient data recovery tool that can effectively recover all data in extreme data loss situations but recovering data from a zeroed drive is sadly not possible. Although this superior data restorer tool can recover deleted or lost data from a formatted / reformatted / partitioned /repartitioned drive with ease. Remo Recover is built to scan, detect and recover more than 300 types of file formats (this includes almost all major digital data stored on any drive) from an external / internal hard drive memory. So, better you keep a copy of your data before you perform such an action.
