Sata is not detected

February 24, 2009 at 06:00:30
Specs: Windows XP, Intel core2 2.67GHz duo/2M
My computer was working properly until my AVG antivirus was automatically disabled and made me reboot the pc. (I beleive it was all done by a virus). From then on, my SATA 500G hdd is not recognized by the CMOS!
I flashed the CMOS but it didn't work.
Please tell me if there is any virus that can lead to such results? If yes, please let me know how I cam overcom. Else, what is the issue?
Please help

....one does not flash the harddrive unless it is the very last thing to do to repair a system....not the first thing.

Your problem is probably a bad harddrive. They will demonstrate symptoms that resemble a virus or trogen when they go out sometimes...really slow....lock-ups....auto reboots...not booting.

If you have another SATA drive swap it out and see if it shows in the BIOS. This will eliminate a bad wire issue and also help determine whether it is a bad drive or not!

Unfortunately I have no other SATA drive! Is there any other way you can suggest ?

go to the drive manufacturer's website and somewhere under support will show a installation utillity application that can be downloaded as a bootable CD or floppy diskette. Use whichever your computer will allow and follow the instructions for making the download bootable.

Reset the boot order to the computer BIOS and boot to the CD/floppy and have it check the drive. If it detects it then run the diagnostics and see what it finds and follow the suggestion for repair option if any!

Malware MAY disable AVG or other anti-malware programs but it it rarely causes a computer to reboot. You probably have something else going on.

What may cause a computer to reboot?

- if it went to a BLACK screen, not a BLUE one before it rebooted

- Failing power supplies are common and can cause your symptoms.
Check your PS.
See response 4 in this:
http://www.computing.net/hardware/w...

If the power supply is not producing enough +12v or +5v, your SATA hard drive requires both of those and it may not be detected if either of those is inadequate.

If there is no +5v, you also have no working USB ports, and your CD or DVD drives cannot work.

- A common thing that can happen with ram, even ram that worked fine previously, is the ram has, or has developed, a poor connection in it's slot(s).
This usually happens a long time after the ram was installed, but it can happen with new ram, or after moving the computer case from one place to another, and I've had even new modules that needed to have their contacts cleaned.

See response 2 in this - try cleaning the contacts on the ram modules, and making sure the modules are properly seated:
http://www.computing.net/hardware/w...

......

Sometimes under certain circumstances the computer will black screen AND reset the bios to defaults. In some cases that creates a situation where a drive with an operating system on it that booted fine previously does not boot, r because it's no longer the first hard drive listed in the default boot order settings, and/or default settings are not detecting the drive. Check the bios settings to make sure the drive with the operating system on it you want to boot is listed first in the boot order, and that the controller connection the drive is connetected to is set to Auto detect by the method Auto or LBA.
.....

Check your SATA data cables. The connector on each end should "latch" into the socket on the drive and on the mboard, or on the drive controller card - it should not move when you merely brush your hand against it near the socket - if it does, mere vibration can cause a poor connection of it - use another SATA data cable that does "latch", or tape the connector in place.
(There is a slight projection or bump on one side of the outside of the connector that "latches" it into the socket - it's easily broken off or damaged)

Also check the power cable connection to the SATA drive to make sure it's seated and it "latches" too.
..........


- if the computer went to a BLUE screen before it rebooted, that can be caused by a software or a hardware problem.

......

The mboard bios MUST recognize the hard drive in order for you to be able to test it with the hard manufacturer's or other diagnostic software. If the hard drive is not spinning at all it cannot be recognized - that's a lot more likely to be caused by a failing power supply or a dying mboard than the hard drive actually being faulty.

Oops - I mis-read your post - you rebooted the computer yourself.
However, if you have gotten black or blue screen reboots as well, or in any case, the same things I mention could be your problem.
I'm assuming you have a desktop computer, but some of these things can be a problem on a laptop too.

If the AVG icon in your taskbar lower right turned black/grey, that usually indicates you need to reboot the computer for changes made updating the AVG software to take effect, NOT that it has been disabled by any malware.
AVG 8.x updates itself in the background, and it and AVG 7.5 sometimes requires you to reboot in order to have update changes to the AVG software to take effect.
