Hard disk problems, Clicking disks. CAN the Disk Configuration information be restored on hard disk ???

I ran into, multiple disk 'crash' problems (different systems) where the boot process often could not find the disk any more and the device starts Clicking(Click of dead).
I know the only sollution is a "Backup". But investigating the problem I remarked something odd. And I'm looking mainly for knowledge, and possibly a way to recover more data.
So you can eventualy refer me, But please only to relevant info not the genereral stuff.


As I consider non BIOS connecting disks(no info in startup) as trash, I have a whole stack of them by now IDE/sata/scsi ....
I noticed, every once and a while You can still see them connecting to the BIOS. Esspecialy after trying the refrigerator solution.
I often noticed, an odd Device name, as I'm using information maagement programs is see corrupted data in the information management part of the disk.

Device name = corrupt
device configuration ( sectors/blocks ....) being corrupted as 0 or -1 or ....)

with those configuration values it seems only logical, to me, that the device starts clicking(goes to the impossible location... hits a boundery and reset's)
As this resetting process takes for ever there is no time to look at the host bios and report anything to the Bios/hosting PC.
As i get through, the data on the disk itself seems fully accessable intact and read /writtable (block edit tool) so electronicaly and physicaly nothing seems wrong.
eccept for the configuration information....

All the symthoms seem to be explained by this theory. BUT: I can not find a way to reset the configuration to reset the situaton.
Is there anyone who can help me on how/tool/possibility? .... to reset that information clearly stored somewhere on the disk.

as general programs can read this data; is this a per supplier setting ??? can it be rewritten or is it to be baked from the factory only.
is it located on a commenly agreed location ? can it be altered ??? where is it ?

restoring the info completely or partualy would at least give me insight, potentialy help myself and others to recover more disks
All remarks welcome!

If you consider the clickers to be trash then feel free to open them up and have a look. The click is usually the head resetting because the drive was unable to ready is system section of the platters. Sometimes this is because of a bad head or two or a stuck head. Resolving the head issue may give you enough time to recover the data.

Correct , right ..... please reframe from the general stuff iknow.
But this was not the question.
It seems that the Config setting on the disk is wrong all the rest seems readable....

if I could reset these device parameters,... I would be able to recocer I think?
But the forum is more experienced in this ?
-is my theory about the config block acceptable ?
-Are there tools to actualy address these config information on the disk
I seem to be able to handle a lot (smart/ noise/ landing zone (some tools) but never the config blocks.

"If you consider the clickers to be trash then feel free to open them up and have a look"

I suspect the Manufacturers config declaring size and ..... is corrupt

This of coarse (invalid values) forces the disk into repetivly resets....

I'v ton's of passive tools (herin/ universal boot)that can read all kind of parameters on the disk.
I can even edit the blocs on random positions.....

Is there a tool or a way a procedure .... to somehow restore that manufactering Block
or do I ALWAYS need to throw away the disk ....??
