Hello Friends,

Googling about process defect list error, i found it is releated to sys file 1B problem. i need data. Can someone repair or rebuild 1B file. I attach important sys file as attachment.

Thank You.

"repair or rebuild 1B file"
It is impossible to fix. In both copies the beginning is erased with zeros.
And the most important thing is 512 bytes of the beginning of the factory P-list.
This is assuming that the T-list was empty at the beginning from the factory.

Any hope to retrive the data?
it is erased with zeros automatically or by someone?

I don't have any. Maybe someone does.

can you rebuild 1B file wuth the help of 1F file?
I read 1F file also completely without error.

it is perfectly unnecessary if that 28 is native. do not regen.
what tools do you have?

i haven't any expensive tools.

pepe sir did you download my original files.rar? are you found any problem in 1B file?
if not, why error message come when regenerate the translator?

[pepe]

i checked your files after my first msg, then i saw there is 028 in perfect condition, that's why i can't get why you want to regen it.
as SWM said, 01B is corrupt, first part seems to be erased, it cannot be repaired but it is not necessary.
With tools and knowhow this thing should be easy. without tools it is a bit though, without knowhow you better outsource it... :s

Pepe sir basically hdd have partial access problem so, how I solve this problem? Is 1B File is not essential for data recovery?

[SWM]

I don't know how easy it will be... Of the tools, only the terminal is visible - it is visible by the file format.
In 35 there are only three entries at the end of the LBA. How "native" 28 is - one can only guess.
Apparently, everything that was found on the Internet (A>P and even 6F) has been done with the disk.

Dear SWM sir,
Can you guide further me regarding A>P and 6F

[SWM]

Dear kagzizaid80 sir,
These commands only do harm. Especially to data recovery.
As well as recalculating the translator without a backup of system files.
And it is impossible to restore erased P-list records. They are unique for each disk.
For your level of knowledge - listen to the pepe:
"without knowhow you better outsource it..."
