Study Notes
- Organizations often donate or destroy old devices when upgrading, removing storage components to prevent unauthorized access to corporate data.
- Shredding is an effective way to ensure data is unrecoverable, involving large industrial devices or physical destruction with drills or hammers.
- Electromagnetic means, such as deguassers, can also destroy drives by removing their magnetic fields.
- Incineration is another option to ensure no data can be recovered.
- Many organizations have large numbers of drives to destroy each year, often outsourcing to third parties who provide certificates of destruction.
- Manufacturers provide a low-level format at the factory, followed by standard formats that remove data in varying degrees.
- Quick format only removes the drive index, leaving data intact and potentially recoverable.
- Regular format overwrites all data with zeros, making it unrecoverable.
- Secure delete functions, like Sdelete, allow selective overwriting of data while keeping the rest intact.
- Third-party utilities, like DBAN, offer secure delete options and multiple overwrite passes for peace of mind.
- A 2019 study found that 42% of used drives purchased from eBay contained sensitive data, including personal information and emails.
