Yes, agree with all.
I think there is some problems with the terminology the OP is making. Hopefully those can be cleared up.
In post #6 the OP says "The drive is an IDE".
The "drive" (physical HDD) is most likely a modern SATA drive. I can't imagine a PATA drive ever made at 4TB.
In post #3 the OP says: "It is a SATA drive"
Also notice in post #6 that OP says: "Because my pc is AHCI"
Which would indicate that the BIOS is set to AHCI and Windows was installed in AHCI.
THe OP says the HDD is seen in BIOS, just not in Windows (Post #3)
I think this is all causing some confusion, thanks to the Google IT department.
I think we can assume this is a standard SATA HDD connected to a modern motherboard with standard SATA power and data cables, and it is recognized in BIOS, and work from there.
