Samsung HD300LD sv_tbl erased but have backup

[TerraNova]

Hi guys please help.

I stupidly erased the Mod #5 SV_TBL on Samsung HD300LD, i have the original backup but i cant rewrite it back.

I have set the drive to safemode Master, Slave and CS, i tried rewrite but failed.

Any help much appreciated.

Hotswap?

Won't work. It will most probably click when init again or won't be able to write to the MC. I have just developed a solution to rebuild the tables - under test ! - and tools to gain access to the MC when usual ways like Pc3000 fail, but I'm on opposite side of the world...grunt!!

Tried today, hotswap didnt work out.

I told you

Let me just add another

If other less critical tables are missing or damaged hotswap could be an option, but not with critical modules that are always loaded when you wake up the drive !

what if u write the tables into the RAM, then try to write to the surface?

You can't write anything to the surface until the drive is "decently" initialized and of course the servo tables are loaded. It seems a dead end. I have a proprietary solution but is not applicable because of the distance. Wish I was near him :S

You can't write anything to the surface until the drive is "decently" initialized

that's why I think writing the tables into RAM (thus completing the incomplete initialization) we could restore the capability to write the SA itself

... and then how can you make the drive think it is correctly initialized ? It's not like Maxtor where you can jumpstart with LDR and/or RAM.
If you send SR the drive does not enter the operational state, it will problaly start trying loading the entire fw again/recal (click...click....click.....).
If one of the xLists is missing but you have the rest, you can do something, but if servo reference data is missing, the drive itself can't start. Not this way. Anyway your theory is worth a try : I'll recreate the TerraNova's environment on a PALO then I try your hypotesis.

He has the original tables. just cannot write them.
It is just an idea, there is much to do to get it work I think.
Like collect the info where these tables are loaded in RAM, what else must be changed to make the drive think they are loaded,
write some prog to write the proper data to the proper memory addresses...
and test the result.

not a one hour work... and I don't have the time to experience with it...
