Unlike non-destructive tests, any data present on the media prior to the test beginning is lost. FDAT allows for enabling or disabling destructive tests, as well as specifying a range of destructive and non-destructive sectors on the tested drive. This is done through the configuration of the FDAT.INI. If destructive and non-destructive ranges somehow overlap, then the overlapped area is considered non-destructive. For example, if users specify both destructive and non-destructive ranges as the same, then the entire drive is tested as non-destructive. Quick and Full erase - hard drive The Diagnostics program offers two hard drive format utilities: v Quick Erase Hard Drive v Full Erase Hard Drive The Quick Erase Hard Drive provides a DOS utility that performs the following steps. v Destroys the Master Boot Record (MBR) on the hard drive. v Destroys all copies of the FAT Table on all partitions (both the master and backup). v Destroys the partition table. v Provides messages that warn the user that this is a non-recoverable process. 18 Hardware Maintenance Manual

the
