• Scratches on Hard Drive Platters:

The platters inside a hard drive, which store data are extremely sensitive and susceptible to damage. Even minor scratches or contamination on the platter surfaces can lead to permanent file loss.

When the read/write heads attempt to access files on a scratched or damaged area of a platter, they may be unable to read or write accurately, resulting in file corruption or loss. It’s impossible to restore files if the platters have severe scratches or rings.

• Data Overwriting:

When data is overwritten, the original files are permanently lost and cannot be restored. This is because the new data overwrites and replaces the previous data at the physical level, effectively erasing it from the storage medium. Once file have been overwritten, there is no way to retrieve the original data.
