Abstract
The invention discloses the methods of bad failure after being got well before a kind of reparation Hitachi hard disk, belong to hard disc data and restore field, 01 obtains firmware chorography module, and parse the buffer address of P tables；02 reads the P tables position of 0, if there is bad track just skips bad track and records；The P tables position of 1 is read again, if there is bad track just skips bad track and records；Finally the data by 0 and 1 reading are combined, and repair out a complete P table；03 reads content and preservation of the ram data lengths for 512 sectors；The complete P tables that step 02 is repaired are loaded into hard disk cache by 04, and hard disk is made to establish correct compiler.Beneficial effects of the present invention are as follows：It is backed up present invention utilizes the hard disk P tables of 0 and the P backups of 1 has been reassembled into a complete P table, then pass through the loading to P tables, you can the reparation of bad failure after good before realization Hitachi hard disk.
Description
Technical field
The present invention relates to hard disc datas to restore field, the side of bad failure after being got well before more particularly to a kind of reparation Hitachi hard disk
Method.
Background technology
It is put when the P epitopes in hard disk firmware area of Hitachi and bad track or damage occurs, it is impossible to the situation for normally being accessed and being loaded
Under, the data field of Hitachi's hard disk just can not normally be accessed, that is, will appear it is preceding it is good after bad situation.The specific form of expression is,
The data of the previous section sector of data field, can normally access.The data of the higher value LBA positions of data field, can not be normal
It accesses.Bad failure after being got well before the appearance of such case, referred to as hard disk.The reason of causing this failure, mainly hard disk firmware area
P table modules there is bad track or damage, can not normal load when hard disk itself is caused to load P table modules so that hard
Disk data field can not normally access.
Invention content
In view of the deficiencies of the prior art, the present invention provides the methods of bad failure after being got well before a kind of reparation Hitachi hard disk, realize
Before Hitachi hard disk it is good after bad failure reparation.
To solve problem above, the technical solution adopted by the present invention is as follows：Bad failure after being got well before a kind of reparation Hitachi hard disk
Method, include the following steps：
01 obtains firmware chorography module, and parse the buffer address of P tables；The label PSHT of P tables deviates 12 backward
The content of four byte records after byte is the buffer address of P tables, four byte records after buffer address it is interior
Appearance is the valid data length of P tables；
02 reads the P tables position of 0, if there is bad track just skips bad track and records；The P tables place of 1 is read again
Position, if there is bad track just skips bad track and records；Finally the data by 0 and 1 reading are combined, and repair out one
Complete P tables；
03 reading ram data lengths are the content of 512 sectors and save as L；It is looked into ram data contents after the completion of reading
The value N of matching " 4FF07042801A71F1030103D202484078012800D000207047 " form is looked for, after matching value N
The contents of four byte records be to need the address value M that changes, M is saved as into A4A3A2A1；Finally it is displaced in L
OxA4A3A2A1, then read the content of two bytes and the address of two bytes is written；
The complete P tables that step 02 is repaired are loaded into hard disk cache by 04, and hard disk is made to establish correct compiler.
As preferred：If step 02 cannot repair out a complete P table, directly exit.
As preferred：After being got well before reparation Hitachi hard disk before bad failure, first judge Hitachi's hard disk with the presence or absence of bad after preceding get well
Failure.
As preferred：Judge that Hitachi's hard disk is as follows with the presence or absence of the specific method of bad failure after preceding get well：Directly access sector
Data；The position of LBA before, during and after access；If preceding-OK, in-OK, rear-NO, be it is preceding it is good after it is bad, otherwise exit.
Beneficial effects of the present invention are as follows：It is backed up present invention utilizes the hard disk P tables of 0 and the P of 1 backs up group again
A complete P table has been synthesized, then has passed through the loading to P tables, you can the reparation of bad failure after good before realization Hitachi hard disk.
Specific embodiment
To make the objectives, technical solutions, and advantages of the present invention more comprehensible, referring to embodiment, the present invention is done
It is further described.
The method of bad failure, includes the following steps after being got well before a kind of reparation Hitachi hard disk：
01 obtains firmware chorography module, and parse the buffer address of P tables；The label PSHT of P tables deviates 12 backward
The content of four byte records after byte is the buffer address of P tables, four byte records after buffer address it is interior
Appearance is the valid data length of P tables；
02 reads the P tables position of 0, if there is bad track just skips bad track and records；The P tables place of 1 is read again
Position, if there is bad track just skips bad track and records；Finally the data by 0 and 1 reading are combined, and repair out one
Complete P tables；
03 reading ram data lengths are the content of 512 sectors and save as L；It is looked into ram data contents after the completion of reading
The value N of matching " 4FF07042801A71F1030103D202484078012800D000207047 " form is looked for, after matching value N
The contents of four byte records be to need the address value M that changes, M is saved as into A4A3A2A1；Finally it is displaced in L
OxA4A3A2A1, then read the content of two bytes and the address of two bytes is written；
The complete P tables that step 02 is repaired are loaded into hard disk cache by 04, and hard disk is made to establish correct compiler.
Further：If step 02 cannot repair out a complete P table, directly exit.
Further：After being got well before reparation Hitachi hard disk before bad failure, first judge Hitachi's hard disk with the presence or absence of bad after preceding get well
Failure.
Further：Judge that Hitachi's hard disk is as follows with the presence or absence of the specific method of bad failure after preceding get well：Directly access sector
Data；The position of LBA before, during and after access；If preceding-OK, in-OK, rear-NO, be it is preceding it is good after it is bad, otherwise exit.
