I have seen in a certain forum that one of the steps used in resolving the above problems (using Terminal) says: "To correct 0 LBA error, you'll need to do a quick format in order to regenerate the partition, just with m0,2,2 and the rest can be left blank by putting only commas or filling out with zeros. At the end you need to use a "ValidKey" code, or 22."

What is bothering me is the part that says "a quick format in order to regenerate the partition". Does not this step destroy used data ? If yes, how can the problem be rectified without destroying used data ?

Thanks for any info.

I followed the 7200.11 tutorial and was able to get Data. YMMV and I suggest reading very carefully and make no mistakes with commands. Also read up on the part where we discussed the correct parameter. There is my thread on HDD Oracle to look at.
cheers

It is a "poor choice" of wording if you will that leads to wrong interpretation of what exactly is happening.
The command "does not format the partition", it rather recreates the proper translation for the partition. There is a high degree of complexity behind those m0 2 2 etc. numbers within the command. They each have a specific purpose. Typing the "wrong number" within the command may/will likely screw things up, especially among other Seagate models and so on.

A different specific set of numbers does have the ability to destroy the data, hence what I mentioned above is dangerous when applied without deep firmware understanding/knowledge.

Thank you HaQue, labtech.

I am better informed now.

labtech,

What I have understood from your post is that different Familes (models) of HDDs can have the same UBA number for different modules or different UBA numbers for the same module in SA. Thus a certain command can be mistakenly applied to the wrong module in a different HDD and cause unpredicatble damage.

My question is, where in the hell can I get those UBA numbers ? Of course, apart from googling my @$$ out. Any help is greatly appreciated.

Thanks for usual help.

Advanced research in various forms, not just Google.
