YES data can be recovered from a zerofilled hard drive but it is extremely difficult and costly process. To recover data from it one has to use a special equipment that has the ability to detect What new zeros have been put on the magnetic plates of hard drive. The process involoves detecting and separtating older magnetic field from the newer one. Let me explain it by an example: Consider a piece of data: 10110101 When you will zero fill the data will become 00000000 As the drive is formated all ones are converted to zeros. In this process new zeros replace the older ones but the older zeros remain "in place". This causes magnetic fields of slightly diffrent intensities on the surface of the disk i.e., the magnetic field of older zeros is of lesser intensity then that of the newer zeros. This change can be read by special equipment under special conditions . This is how FBI recovers data from a ZERO-FILLED hard drive. Hoping this will answer your question. Awais Rauf.

How do you fix your hard disk after its failed and data has already been recovered?
As you have recovered data from the failed hard-disk, it would be best to buy a new hard-disk.

How to recover a lost disk?
The simplest way to recover a lost disk is first to determine if the disk can be recovered from the hard drive or the recycle/trash file. If this is not possible, data recovery programs can be purchased to recover the data.
What are the functions of a hard disk?
A hard disk acts as a storage device for data. Data is also retrieved from the hard disk. The data that is kept in the hard disk is not erased even when the computer is switched off.
What is collection of related data stored in a hard disk?
collection of related data stored on a hard disk
How much old data can be recovered from a working hard disk?
All of the "old data" that has not been overwritten can be recovered in Windows and MS-Dos. When a file is deleted in Windows / MS-Dos the first character of the file name is changed to a question mark. This releases the allocated disk space of the deleted file to the free disk space. The data itself is not touched until a program overwrites the data in that allocated space. This is not true of most other operating systems.
What is it called when one Randomly writes magnetic ones and zeroes to a hard disk?
It is known as overwriting, in which a program is used to write zeroes and ones on the hard-drive. Several passes may be made to ensure the original data has been completely overwritten. Simply formatting a hard-drive is no good, as the data is still on the hard-drive, only the links to the data is removed, and the data can be recovered.
Where the formatted data go from Hard Disk when you format the Hard Disk?
The data is still there. When you format a disk you're just telling the hard disk controller that the disk is effectively empty and it's okay to overwrite any data that may be on it. This is why "undelete" programs work.
Cost of hard disk recovery?
There is not a single answer for this. It all depends on which system you have and how much data needs to be recovered. Most sites will quote you a minimum of $40 to a maximum $3500.
Where data can be stored?
Data can be stored on floppy disk, hard disk, memory stick, CD or DVD.
How could one recover data from a dead hard disk?
One way of recovering data from a dead hard disk would be to get it repaired at a computer shop and buy an external hard disk enclosure that is compatible with the hard disk. Then you can mount the hard drive and transfer data across to the desired computer.
