This format is very resistant to error due to a garbling reply from another aircraft . To cause a hard error one pulse has to be cancelled and a second pulse inserted in the other half of the bit period.
7.
While most RAID levels can provide good protection against and recovery from hardware defects or defective sectors / read errors ( " hard errors " ), they do not provide any protection against data loss due to catastrophic failures ( fire, water ) or " soft errors " such as user error, software malfunction, malware infection.
