WD Marvel is a cheap firmware tool that should do what you want. Otherwise you could use NazYura's freeware to retrieve your drive's firmware resources, or you could try HDDSuperTool.
Ddrescue is able to skip bad sections of the drive. Perhaps you could use it to image the bad area.

Have you seen a case, where a head survived a crash?

G-List is a list of defects that are found during the use of the drive. Those sectors are "swaped" by a spare.
It would be like this, LBA 1, 2 and 3 would link to physical location A,B and C. when you add LBA 2 to G-List then LBA 2 will link for example to physical location X, the first available spare. What you state doesn't make sense.
The drive wouldn't "skip" a section because of G-List. It would either be bad and couldn't be read (the area) or you might have translator/zones/firmware related issues that prevent access to an area/tracks but that is not likely at all.

i think your drive has only 1 head.

I've seen literally hundreds of cases where heads had crashed against the platters but still worked. In fact I'd estimate that half or more of the bad sector cases we see are a result of that. It could have just been a momentary bump that didn't mangle the head, but made a hairline scratch in that spot just enough to prevent proper reading.
I do find it odd that it's not letting you read any sectors in that area, but I suspect it's just due to the fact that you're software imaging. Could be that the sheer number of bad sectors in that area causes the drive to become unresponsive because you don't have the capability with a software tool to disable the read look ahead buffer.

Thank you very much for the information. I hope you're right

+1 ,
He is Damn Well Right Buddy .You Claim To Use a HiFi Sector Cloning Software ,I Sense in Your Posts That Do Not Have Much Knowledge About HDD's in General ,Maybe Its time To Try Something Better DDrescue With a Graphical Interface
