Oneself start work deliver hard disk data
From;    Author:Stand originally

To save the data in hard disk effectively, besides regular the ground undertakes backing up working beyond, learn to be when hard disk occurrence breakdown even how hard disk of bring back to life, perhaps give useful data from the extraction in bad section, fall the loss to the smallest degree.
1, the system does not identify hard disk
The system cannot be started from hard disk, move from A Pan Qi also cannot enter C dish, the monitors a function automatically to also cannot discover hard disk presence in use CMOS. This kind of breakdown appears on join cable or IDE port mostly, the possibility of breakdown of hard disk itself is not large, can receive hard disk cable to perhaps change through be being inserted afresh IDE mouth and cable undertake replacing an experiment, with respect to the place that can discover fault very quickly. If receive the hard disk that go up newly to also be not accepted, a common cause is the principal and subordinate on hard disk jumps line, if facility of two hard disk is received on line of an IDE hard disk, be about to distinguish Hunan principal and subordinate to concern.
2, the trouble that CMOS causes
Use what the hard disk type in CMOS affected hard disk correctly directly normally. Present machine supports " IDE Auto Detect " function, can detect automatically the type of hard disk. When mistake of hard disk type, sometimes flat cannot start a system, can start sometimes, but can happen read clerical error by accident. For instance the hard disk type in CMOS is less than actual hard disk size, criterion the fan area at the back of hard disk will not be read write, if be much more divisional condition,individual partition will be lost. Still have a main breakdown reason, because current IDE backs logistic parameter kind, hard disk can be used " Normal, LBA, large " wait, if data was installed below general pattern, and the mode in other of the instead in CMOS, meet those who produce hard disk read write wrong breakdown, because of its map relation has been changed, will not read take place of original correct hard disk.
3, advocate the starting trouble that bootstrap causes
Advocate bootstrap is located in hard disk advocate lead fan area, basically use 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 after be being started from soft drive or CD driver, can undertake reading writing to hard disk. Repair the method of this breakdown is relatively simple, the FDISK that uses tall version DOS is most convenient, should take parameter / when Mbr moves, will change directly (rescript) of hard disk advocate bootstrap. Actually of hard disk advocate this program builds lead fan area, the bag contains complete hard disk in FDISK.EXE advocate bootstrap. Although DOS version is ceaseless newer, but of hard disk advocate bootstrap did not change all the time, arrive from DOS 3.x the DOS of Windos 95, should find a kind of DOS guiding to Pan Qi uses a system and run this program only can repair.
