A solution for a case like this...

[smecca]

Well, assuming that g-list is lost in both A-B SA and that c is also corrupted in most of modules it will be a problem to me to get data back from this N40P family drive.
When it comes in my laboratory it went in ready status but sectors were unreadable.
So Downloaded fw from both A+B and the fw from donor drive ('cause a lot of bad-s were in SA), compared all and rebuild almost all modules except that of g-list corrupted in both areas. So lformat SA and uploaded modules. (firstly rescanned SA to update U-list and, as many sectors were damneged as more that U record can stands, i removed all records corresponding to non-critical modules addresses. So finished uploading all the fw and get back drive full functionality.
Now, inevitably, with an adapted g-list I got unstructured datas, and, at first scan, we recovered 3 % of datas in raw mode (( .
I go at the question:
Any Suggestions to crab this hdd ?

Clear glist and use virtual translator. Probably you have a lot of shifts.
