My hdd is maxtor 4D040H2. not detected in bios, when hdd detection (in bios), it spend a long time to detect (about 1 minutes) but undetected too.

I have some question :
I heard that upgrade HDD firmware can fix it. Do you think so?
I heard that upgrade bios firmware can fix it. Do you think so?
I heard that upgrade HDD mobo can fix it. Do you think so?
What is HDD mobo?

Thank's for your answer and helping.

HDD Firmware? Short answer, NO. Longer answer, very slim chance it might fix it, but all this depends on WHAT'S WRONG.

BIOS? Short answer, NO. Longer answer, not unless if there was a SERIOUS bug in the BIOS. Forget that one.

MOBO is short for Motherboard. If you have another computer, simply test the hard drive there. If you have another hard drive, you can test the BIOS and 'MOBO'. If you have none of this, take it to a computer repair place. If you are unable to diagnose properly, you'll spend more money replacing random parts than if you took it to a professional, and you still might not have a working computer. The key to fixing any problem is to properly diagnose and understand the problem first.

Sorry, I didn't realize you were the person from the other thread. Give a Firmware upgrade a try. The worst you can do is break a broken drive. The rest of my above advice holds.

Thanks.... I would try it.
