WD400BB-00CAA1

Hello, I'm having trouble with this old drive. I can't use full capacity. The nominal capacity is 40GB but I can use only 36.8GB.
I use this setup:
ASUS P4P800-VM with Pentium 4 2.4GHz
Drive is connected to Primary IDE with 80 core cable on master position with no jumpers. In BIOS in IDE Configuration I tried to select both Compatible Mode and Enhanced Mode.
The drive works otherwise normally. I can format it, move files and so on.

Here is what I tried:
hdat2:
In security menu are all options red - this command will be aborted.
In Hidden areas menu no option available which would allow me to change anything.
It allowed to dump a module 42. (In attachments above SMART data photo)

MHDD:
NHPA - ends with fail.
CONFIG - ends with fail.

ZU (to delete ATA password):
command zu /P
says NO PWD.BYE! --> this message it showed only when the IDE Configuration was set to Compatible Mode. In Enhanced it was only measuring time.

Thanks for your help with helping me to solve this problem!
