Must be:
Primary IDE chanel :Hitachi HDT725032VLA360;V54OA73A.
And Windows not start , - no HDD.
I have "Hirens Boot CD" , but all programs in "HDD Tools" says "no hdd".Only "Gateway GwScan" wiew my hdd ,then i reboot , and everything is fine.

It appears that your drive is Powering Up In Standby (PUIS).

Here is one solution:

Recently my hdd Hitachi was sounding as "click-click-click..." (I may send you a mp3- recording of this sound) and didn't determined by the OS at the same time, while I was leaving the PC turned on for a day, for example, to upload media content, or defragmentation.
shutdowning the PC and booting PC again solves the problem, but the problem was reappeared from booting to booting. I've check the hdd by program HD Tune Pro 5.00 - it shows "All is OK".
See the SMART:

Then I set the Enabled (was Disabled as default) parameter "HDD S.M.A.R.T. Campability" in CMOS for both hdd-drives, connected to PC.
After that the hard drive Hitachi began to work normally and more quite for 6 months, but after that the problem has returned. I've removed bottom electric plate and cleaned it with an eraser. Have changed the SATA cables and connection ports - No results. I've plugged a new Seagate for backup to the same port - it operate normally. Should I check my troubleshutting Hitachy by MHDD? On what parameters I should pay attention in this case?
My motherboard - Gigabyte GA-P35C-DS3R rev 1.1. BIOS ver F2, I have n't updated its since 2007. Should I Update the BIOS of mb or Hdd's?

Name of drive Hitachi HDT725032VLA360 (320 GB). It was bought in 2007. But worked since 2010. operating time of 3300 hours use. resource? Maybe less of 50%

Can anybody help me?
