This method can completely restore Seagate LM series without bad problem after getting well before backup firmware, in the feelings that no firmware backs up
Under condition, many original data reconstruction method modes are all invalid, and data can not be recovered completely or not restored not come out at all.
Data can completely be restored using our scheme.Can quickly handle simultaneously LM035LM007 it is preceding it is good after bad problem,
Without using traditional scheme for adding PBA one by one.The general common traditional scheme processing time is very long also not necessarily to be handled successfully.
This programme is can disposably to add thousands of up to ten thousand PBA to NG tables, bad problem after directly quickly processing is preceding well.
It is badly because LBA (logical block address) goes out with PBA (physical block) address after the hard disk of LM035LM007 is good before occurring
Caused by existing entanglement, what we to be done is exactly that their correct corresponding relationships are found out.Use one section of address PBA for falling block
This section of PBA for being added to NG table (in Hard Disk Defect table) addition NG table will be no longer accessed.
Three magnetic head series need by hand plus PBA to NG table can run semi-automatic program work.
Using m0,6,3,,, 22 instructions regenerate compiler, be allowed to LBA pair PBA rearrange.In Seagate LM
In the hard disk of this model use traditional instruction m0,6,3,,, 22 rebuild once at 3 minutes or more, so we before use
Mode PBA is added to G table one by one, then reuse m0,6,3,,, 22 turns of NG tables generate the mode of compiler with regard to not all right
?.Because one bad point PBA of the disk of Seagate LM series be it is very one section long, if still going to add one by one with pervious method
Add, needs more than ten month even more long time like that.So we add after having investigated this completely new scheme programming now
Add among program, can once enter plus hundreds of thousands PBA directly to NG table editor.
After load use m0,6,3,,, 22 generate compilers after, LBA can normally have accessed.Then we can
Restore to extract data to complete data.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the principle of the present invention, it can also make several improvements and retouch, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
