SAMSUNG problem
June 28th, 2008, 11:03
Need "urgent" help or better, advice.
I have a SP1203N 120GB (Palo) for data recovery. The system froze, after restart the PARTITION inside the drive could not be accessible again (the drive seems unformatted). The drive is correctly recognised by BIOS , BUT...
1) The data INSIDE seems to be SHIFTED because of errors in DLIST.
2) MHDD show a lot of errors but it's supposed to be like that.
3) I successfully "cloned" (forensic) the drive to another in order to try logical recovery, but with "knocking" (despite the fact the cloning is successful, 0 errors) and with many areas extremely slow in copying.
An in-depth analysis of the MC shows that , trying to SAVE the MC, I get a read error at sector 501 track 0 head 1 - DLIST (hope I remember correctly).
Some of the modules can't be fully read (i.e. DLIST, heads knocking).
Relevant modules are OK.
As a result, in the "imaged" drive I cannot find some of the folders needed.
I think it's like P-LIST problems in Maxtor, the data shifts and the drive seems to malfunction (slows, errors etc. due to incorrect handling of relocated BADs).
Any GOOD advice / starting point ? If the answer is too technical and don't want to put it here, please PM me.
Thanks.

Hello,
Did you try hotswap?
I think, this solution is close to a good.
You only loose the sectors in defect lists.

Yes but I don't have an identical drive... That's why I asked for advice! Thanks anyway, NC. Any other idea?

The shift is equal for the entire drive?
You can cut or past in the image to getting into the right place.
(I have looked into my stock, but i don't have this drive too.)
At this point this is my best suggestion.

Hi,
when 'plist' is gone, the shift is not constant, unless U have only one continuous area of bad sectors.
So the problem is that u have to regenerate the translator manually from the image.
As far as I know there is such option in DE, but I never used it, so I don't have many opinions about it, as I wrote mine own util well before I bought DE, so I usually use that one. (though I rarely need it these days...)
BTW does Dlist have problems on all 3 heads?

Hi,
Additionally, if the 'plist' works like only skipping bad blocks, the hotswap may not working with identical drive as well.
I have looked this issue before on N40P drive, but another matching donor drive for hotswap solved the problem for me.
