Recover files after a 1 pass zero erase

Specs: WinXP, 2gb
Is it possible to recover files on a hard drive that has been erased using Active Kill Disk (free)?

I used a 1 pass zeros (low security) but now i need to be able to try and recover these files.

Try RECUVA enable deep scan before starting to scan.

After files have been overwritten there is no possibility of recovery them with any software. The only hope, and not a very good one, is a commercial data recovery service. This is very expensive.

Try the Ultimate Boot CD (UBCD). Just create the disk, boot off it, then try one of the recovery options.

1 - One Pass Zeros or One Pass Random

When using One Pass Zeros or One Pass Random, the number of passes is fixed and cannot be changed. When the write head passes through a sector, it writes only zeros or a series of random characters.

This suggests that your data is NOT recoverable by any means.

This is because it writes something to every sector. That something being zero or a random set of characters thereby corrupting anything that was in any sector.

What chance is there of recovery thereafter?

When everything else fails, read the instructions.

In theory possible by reading out of track with narrow heads. NSA or a forensics lab.

In theory it is possible to recover data after it has been overwritten. But it cannot be done with the normal drive access methods, the only kind available to software recovery utilities. To even attempt such recovery you need very specialized hardware and software. The only organizations with such capabilities would be law enforcement, high level security agencies, military intelligence, and commercial data recovery companies.

There has been debate about how much data has actually been recovered this way. The organizations best equipped to do this consider it desirable that the public not be informed.

For practical purposes, data that has been overwritten is not recoverable.

Unless of course you have a backup of your data. And if you don't - why not?
