We often see the following statements in Hard Disk Partitions: System partitions, startup partitions, active partitions, primary partitions, extended partitions, logical partitions, MBR, pbr, DPT, and primary boot sectors. In particular, when I see a lot of misleading information, I will be confused. Now I try to clarify the relationship between several people in the most concise language. If any error occurs, please leave it blank. First, each indepe

Previously designed, the hardware circuit is valid for 5 V by default, and the 12 V power is invalid. Then, the system drives 12 V power, which is equivalent to 5 V first and 12 V later for the disk, this method is applicable to most disks, but for Hitachi hgst disks, cold start (or reboot after 12 V is not enabled, so that reboot after 12 V i

Ghost Win7 flagship disk partition and disk partition table restore recovery method by the Windows7 system home first share to everyone! A partitioned table is a large number of small subsets of data that are grouped into sections called partitions. If the hard drive loses the partitioned table, the data cannot be read and written sequentially, resulting in an inability to operate. If the hard

first, the main control algorithm is not the same SSD is a special algorithm, this algorithm is different from each manufacturer, and is encapsulated in the main control chip. With this algorithm, the data can be distributed evenly to each flash on the SSD, while the speed is increased, the life of the flash is greatly prolonged. More efficient algorithms can be high speed data compression read and write, especially the reading speed can be achieved very high, more efficient algorithm may be f
