I've read many articles in this forum where folks have written data to drives that have known corruption. There seems to be a misunderstanding in general about data corruption senerios and data recovery that I'd like to see clarified for the benefit of all concerned.
If corruption appears to exists anywhere on a drive, it should be considered unsafe to write to the drive. Particularlly if the goal is to recover data. Not only is there a distinct chance the new data will be corrupt, there is also the possibility of overwriting existing data. This includes the following operations on a corrupt drive;
1)Installing data recovery software.
2)Reinstallation of operating systems.
3)Surfing the web (writes chache files).
4)Booting the operating system. Page/swap files are, by default, dynamic. Which means they shrink (create free space) and grow (write data) based on demand.
5)Saving modifications to any file.
Ideally, when data corruption is identified, the drive should be removed from an active environment and installed as a secondary drive in a computer that already has data recovery software installed. This will reduce the potential of writing data to the corrupt drive causing further corruption.
