One, the partition of hard disk



To the hard disk in your hand, the business that should do above all is divisional. The security of the convenience sex that after whether reasonable immediate impact goes to hard disk partition, works and data. We are the commonnest the most serious mistake that the divisional watch mistake that arrive also is hard disk, the degree of different mistake can cause different loss.



If be divisional without the activity mark, criterion the computer cannot be started. But after leading a system from soft drive or CD driver, can read to hard disk write, can pass partition of Fdisk replacement activity to be able to have repair. If be mistake of some partition type, what can cause some partition is missing.



After the hard disk that finish is usually divisional, can form the divisional state of 3 kinds of forms; Namely advocate divisional, patulous partition and blame DOS partition.



In partition of DOS of hard disk Central Africa (Non-DOS Partition) is a kind of special divisional form, it is hard disk a medium area differentiates alone come out to be used for another operating system, right advocate divisional operating system will tell, it is the storage space that is differentiated to go out together. Only the operating system ability inside blame DOS partition manages and use this memory area, the system besides blame DOS partition cannot is opposite commonly the data inside this partition has a visit.



Advocate partition is a purer partition, the foremost face that is located in hard disk normally in an area, make logistic C disk. Among them advocate the one part that bootstrap is it, this paragraph of program basically is used at detecting the validity of hard disk partition, certain activity is divisional, be in charge of a DOS that guides authority to turn over mobile partition or other operating system. Attaint of this paragraph of program will not guide from hard disk, but from can undertake reading writing to hard disk after flexible division or optical division.



And the concept of patulous partition is more complex, create hard disk partition and logistic diskette extremely easily promiscuous; The 4th byte of divisional watch is divisional type cost, the basic DOS partition that normal guidable is more than 32mb is worth for 06, patulous DOS partition is worth is 05. If basic DOS partition type instead cannot start a system 05 times, and cannot be read keep among them data.



If do not know 06 instead DOS,other type is like Efh, criterion DOS thinks to change partition is not DOS partition, cannot read of course write. A lot of people use this type to be worth those who realize individual partition to add secret technology, restore original right kind value to be able to make this partition returns to normal.



There still is other data to be used at record partition in divisional watch initiative or end an address. Confused or what the attaint of these data will cause this partition is missing, cannot undertake resumptive by hand commonly, only method is to use the partition of backup to express data to be written afresh, perhaps be the same as a type from other photographs and divisional state gets partition to express data on identical hard disk, will bring about other data to be lost permanently otherwise.
