Abstract
The invention discloses a method for repairing a front part normal and rear part abnormal fault of a Seagate hard disk sector. The steps comprises the steps of S1, clearing NG-LIST when a hard disk in a disk recognized state; S2, scanning defective pixels in the hard disk sequentially, and adding each scanned defective pixel to a G table and carrying out reestablishment; and S3, determining whether the entire hard disk is searched or not, finishing if the entire hard disk is searched, otherwise going to the S2. The method has the advantages that the defective pixels in the hard disk can be quickly and accurately scanned, both an 512Kb hard disk and a 4K technology hard disk can be repaired, the problem that the hard disk cannot be recognized can be solved, a repairing success rate is high, the repairing speed is fast, and the repairing efficiency is high.
Description
Technical field
The present invention relates to field of information security technology, bad after getting well before repairing hard disk sector, Seagate particularly to one
Method.
Background technology
So-called Seagate hard disk " front good after bad ", refers to that the most a part of sector can be read, but a part below
The situation that sector cannot access.When damaging occurs in Seagate hard disk, it is impossible to access the bigger LBA value in data field
Data, fault bad after having some technology to get well before can repairing hard disk the most on the market, but exist the most several
Point problem:
1. can not repair the hard disk of 4K technology；
2. repair speed the slowest, and have to professional person's operation；
3. can not solve the situation of the nonrecognition hard disk caused because of defect confusion.
Summary of the invention
The present invention is directed to the defect of prior art, it is provided that a kind of repair good before hard disk sector, Seagate after bad side
Method, can effectively solve the problem that the problem that above-mentioned prior art exists.
In order to realize above goal of the invention, the technical scheme that the present invention takes is as follows:
A kind of repair good before hard disk sector, Seagate after bad method, comprise the following steps:
S1: hard disk, under recognizing plate-like state, removes NG-LIST；
S2: scanning hard disk bad point in order, sweeps to a bad point and bad point just adds G table, and rebuild；
S3: judged whether the lookup of DISK to Image, if complete, terminates, and otherwise forwards S2 to.
As preferably, the detailed step of described S1 is as follows:
S101: judge that hard disk praameter state is the most ready, if ready, perform S102, if the most ready, hold
Row S105；
Described judgement parameter state need to call function:
Bool isbusy=ChekDiskStateBusy ()；// detection disk state
If (isbusy==false) exit；// exit
S102: judge whether can with access hard disk No. 0 LBA, if could; would perform S105.Otherwise hold
Row 103；
S103: after electricity left by hard disk, enters T level pattern, enters back into 1 grade of pattern, removes SMART table.
S104: return to T level pattern, removes G table；
S105: return to T level pattern, initializes decoding table；
S106: return to T level pattern, removes NG-list.
In described S106 particularly as follows:
Search NG-list table position；
Search NG-list table and need to call function: FdNGlist ()
Front for NG-list table 2 bytes are revised as 0, preserve and cover original NG-list table address.
As preferably, the detailed step of described S2 is as follows:
S201: scanning hard disk, uses binary chop algorithm, searches hard disk bad point and then performs S202；
S202: obtain cache information, find Default Diag Rd Buf position, it is judged that Default Diag Rd
Whether the BytesPerBlk of Buf is 1040, if then performing S203；Otherwise forward 204 to；
Described acquisition cache information need to call function:
S203: the value obtained by S202 performs S204 after 8；
S204: the LBA numerical values recited that record obtains；
S205: enter 2 grades of patterns, LBA numerical value scanning obtained conversion hexadecimal, use 2 grades
Perform F instruction under pattern, add G table.
S206: use m instruction to carry out hard disk rebuilding decoding table.
Compared with prior art it is an advantage of the current invention that: bad point in hard disk can be scanned quickly and accurately, can
The hard disk repairing 512Kb can also repair the hard disk of 4K technology.The fault of nonrecognition hard disk can also be solved
Problem；Reparation success rate is high, and repairs speed soon, and efficiency is high.
