I have updated the storage controller choosing update driver within storage manager up to 10.0.0.1046m becasue on HP site I found some users reporting about missing disk with version 10.1.0.1008.

Did it update correctly?

No a 64 bit Windows 7

Fter installing the 10.1.0.1008 drivers the disk didn't even show in explorer so I rollback to driver 10.0.0.1046 and the disk showed up again, but always with same problem, if more than 2 Tbyte were full on reboot windows said that it have to check the disk and it deleted some files.

I have finally solved installing an old Promise SATA2 controller (TX2 Plus). Now the disk is showed as 4 Tbyte but on reboot windows says it was not formatted even if recovery tools find all the files. The GPT table is completely messed up.

I don't believe it's faulty because the new controller identify it perfectly.
There is only a problem about the file system index but I believe it depends because there is a mismatch between the 2 copy one up to 2 Tbyte and the other one up to 4. I will use gdisk to se if it can repair.

Doing some research on Internte I found a program that is able to decompress the HP Bios, is called HPdeco.

It extracts all module and I can find the Intel RAID Module, but I don't know how to recreate the BIOS

Maybe you understand how.
