A company is recycling old hard drives and wants to quickly reprovision the drives for reuse. Which of the following data destruction methods should the company use?
Low-level wiping is the best data destruction method for recycling old hard drives for reuse. Low-level wiping is a process that overwrites every bit of data on a hard drive with zeros or random patterns, making it impossible to recover any data from the drive. Low-level wiping also restores the drive to its factory state, removing any bad sectors or errors that may have accumulated over time. Low-level wiping can be done using specialized software tools or hardware devices that connect to the drive. Degaussing, standard formatting, and deleting are not suitable data destruction methods for recycling old hard drives for reuse. Degaussing is a process that exposes a hard drive to a strong magnetic field, destroying both the data and the drive itself. Degaussing renders the drive unusable for reuse. Standard formatting is a process that erases the data on a hard drive by removing the file system structure, but it does not overwrite the data itself. Standard formatting leaves some data recoverable using forensic tools or software utilities. Deleting is a process that removes the data from a hard drive by marking it as free space, but it does not erase or overwrite the data itself. Deleting leaves most data recoverable using undelete tools or software utilities. References:
