WD 1TB Green drive - blank sectors

[mscotgrove]

I have a WD10EADS-00M2B0 1TB drive.

The first 66,000 (approx) sectors read correctly. Almost all of the rest are filled with 0xFF. They read, but very slowly.

The PC the drive was in was affected by a lightening strike. I feel the data may still be present, but not accessible.

If I edit a sector, eg 4,000,000,000 the edit is remembered

I have tryed to regenerate the translation module, (from P and G lists). I have cleared down G and P lists, recreated translation table etc (in all combinations) but no time do I get any data other than 0xFF, and the start of the disk goes to 0x00.

Any sugestions - I have PC-3000 UDMA

The main data is JPEGs so an approx recovery would be fine as data carving would process most of the data

I hope you saved the original modules

This is why professionals are called professionals and newbies are called newbies...

Assuming you have rebuilt your translator "in all combinations and also after clearing P-list, you have very minimal chance of recovering the data in its native file structure.

The first 66,000 (approx) sectors read correctly. Almost all of the rest are filled with 0xFF.

This could be representative of a further problem. Is 0xFF the real value of these sectors, or simply the value returned in case of unreadable sectors? What do you use to view them?

What software/hardware you used to clear defect lists and rebuild translator?

PC-3000 UDMA - and yes I backed up all modules and tracks first, so I can, and have gone back to the original condition.

I am not too worried if original file structure is not 100% valid, I just want to see sectors with data on.

PC-3000 does display an error if a sector is not readable, so I assume this is what is being read.
