The command is as follows: [Root @ qy ~] # Yum installsmartmontools-y Start SMART # Smartctl -- smart = on -- offlineauto = on -- saveauto = on/dev/sd

-effective bit corruption can generally also be enforced with FDISK/MBR override resolution. Partition table corruption is troublesome, because the partition is not recognized, the system will treat the hard disk as an unpartitioned bare disk, resulting in some software can not work. There is also a form of partition table corruption, which I would like to call "Partition mapping", which shows the same partition as the active partition. The same incl

The fourth byte of the partition table is the partition type value. Normally, the basic DOS partition value larger than 32 MB is 06, and the extended DOS partition value is 05. Many people use this type of value to encrypt a single partition and restore the
