Hi all.

Another odd one.

WD1600BB..

Spins up OK.

Becomes ready.

ALL FW modules read OK.

Head test on (on cyl -25), all OK.

But will not read past LBA 392600(approx), all sectos give INF past this point.

Any suggestions on this one?

I have regenerated translator, formatted and re-written SA. No joy.

Did u try wiping that area some times it works .

Yeah, read all modules, wiped SA and re-written.

No joy

Wiping this area will never work. It's IDNF error. Those sectors are simply Not Found.
It's a static translator issue. Before regenerating translator make sure P-List(43) is original.
If you can't get original P-List try to get it from Selfscan logs - Defect lists->Defect lists editing->Defects log in PC3000. Then click Play button - write defect list into P-List of the drive. After that you can regenerate translator. There is a chance P-list was never changed since selfscan on the factory and this will work.

Great work Starling, that's fixed it.

Now running logical scan OK.

Hopefully P-List original will be OK.

If translator is not 100%, I guess to use Virtual Translator in DE to get data back?

Cheers

If there are no IDNF errors while imaging then translator is fine and there are no shifts.
No need in virtual translator in DE.

Well, so far so good 15,000,000 imaged so far with no reported problems.

Having to use DE to image, as my DeepSpar is busy with another job, so going slowly!!

Should be done by morning though.

Once again, many thanks for your help.

Sean

Hmm, logical scan up to 68,009,664 is OK, a few errors but not too many.

After that point, every sector is "Verification error 48-bit (INF)"

Aaaargh!

Sean

look for the original P-List then

I thought I'd done that by getting it from defect log

Where else can I get the original from?

Sean

Defects log has P-List formed on the factory after 1st calibration pass.
Sometimes there is something added after 2nd pass and that's why you got this error after 68,009,664. As I said, it works 50/50.

Original P-List was in module #43. Have you saved it at the very beginning by any chance?

Yes, i saved original in profile in the beginning.

Put that one back, now I am at step 1 again, all bad after 392,496

Sean

The saved P-list has 2942 entries, the defect log version has only 2818.

So, that means that 124 were added on a 2nd pass?

So, I have to manually add the defects from the saved one into the defect log version?

Sean

are U sure the ROM is original?
once I had a case, the drive went to another DR company before it arrived to me. I regenerated the translator and wow (I thought) I could read 1M sectors, then IDNF
I thought Plist was changed, but not, it was identical to the Log...
then I begun trying different ROM images for the same family and for my surprise each time I regenerated the translator with the different ROMs the number of good sectors was different.
Finally found a ROM that fitted and made the whole surface readable.

we respect u

u genius sir
