Add sata HDD

You cannot use a SATA (serial ATA HDD in this machine. You need a PATA (parallel ATA) HDD, also known as IDE, ULTRA IDE, ULTRA ATA. This has a 40-pin ribbon connector & a 4-pin power connector.
Sizes generally available would be 80GB up to 250GB, although very few PATA drives are now sold since SATA is the new standard.

there was wrong in the set up of jumper in your 80gb hdd. Look closely to the 80gb harddrive, in between the ide cable terminal and the power supply connector you will see 8pin terminals paired together and a jumper use to short the paired terminals. It is most likely that the jumper was configure to detect your hdd as master. If the ide cable you use for the 80gb hdd was also use for the dvd/cdrom drive then it will conflict with it if both jumper setting was set to master. See the description of jumper settings in the sticker of the hdd. Position the jumper to slave.

Reboot your system again and see if the 80gb finally appear in your system. When system boot upon detection of hdd, the primary master should be 250gb while your primary/secondary slave will be read your 80gb hard disk.

4 pin moles connector to SATA power connector are available.

845 chipset dont support sata devices and this is common problem that if unsupported device is forcefully bieng tried to work its goona happen sata support started from865 chipset u are lucky that ur hdd is getting detecting

I will advice you to exchange the HDD with someone or with brand new one as it seems to be problem with drivers of the sata.

1. If your system running Windows in SATA HDD, this will not support SATA External HDD
2. Better you try low capacity HDD such as 80GB, this will support and work with your system

thanks

You could try flashing to the latest bios and disabling SATA RAID, disabling IDEs including bus master if u dont use any.

Have you checked in the bios setup of the motherboard if your SATA ports are enabled?

Let me know if you need further assistance.

Change the settings of you IDE drives in your BIOS. Set your secondary boot device to HDD1. Also make sure that your primary HDD is set to master and the secondary HDD is slave. The jumper is found at the back of the hard drive where you connect the power and IDE cables. Try this and post back as to how it went..

Hi LP,
I’ am very familiar with ASUS motherboards. I am thinking you have posted two questions or more referring to the,
ASUS K8V-MX board. When you sign into you're FixYa account you than need to click on you're profile. Within you're profiles are the questions you have posted. Click that question to add or see the expert's answer. If you need another question (about the same item) re-post within that same question. You can even copy the link to an older post & past that link into you're next question. (Than I can read you're last question & my responce).
LP you have me all mixed up. I'll answer the question you have posted above. In the future please provide you're old post so I understand better.

There is nothing wrong with IDE 250GB drive or the SATA drive.
The problem you are haveing is setting the correct settings.

The ASUS K8V-MX can support two serial ATA SATA drives. The SATA drive's can only run at 1.0 version. 1.5GB transfer speed & not SATA II, the 3.0GB speed.

How to setup the SATA drive?
Please disconnect any other drives (IDE) & a second SATA drive that may be connected to the system. Except the CDROM drive.
Using you're manual the SATA drive should be connected to SATA1 port. Page 1-24 in you're manual.
Put you're windows CD into you're CD-ROM drive & boot the PC. You will see, Press any key to boot from CD... (press any key on your keyboard). Windows will start to install. Durring installation of windows the system will restart. You will again see, Press any key to boot from CD... (DO Nothing)!
Just allow windows to conintue on its own. Windows will continue to install it's self. This will happed once again, & again do nothing. Windows will finish installing it's self.
After windows has finished, load the ASUS CD into you're CD-ROM drive & install it's driver software. Restart the PC.
You must register windows. Do so.
Than update windows through windows update service. (This will take some time to complete). (Do not install service pack 3).
If you have an IDE drive 250GB in size & you installed windows on it. You must erase the drive or it will conflict with you're new installation on the SATA drive. To do this, look on the IDE drive & you will find a large white sticker. Printed on there is instructions of how to set the drive pin. Set the drive up as a slave drive. (This is only temporary).
Power off the PC & unplug the power cord. Connect the 250 IDE drive's power cable & data cable. Plug in the power cord to the PC & turn on the PC. Windows will load. Right click once on the start button & slide up to & left click on Explorer.
Find the 250 IDE drive, it should be drive letter D or E. Right click the proper drive letter & format the drive.
( Do Not format, Local_Drive C:\ ). Once the format is complete, power down the PC by clicking on the start button & click turn off the computer. Once off, unplug the power cord. Change the pin on the 250GB IDE drive to Master with a slave. Take the 40GB drive & change it's pin so the 40GB drive is a slave.
Connect the 250GB drive to the end of the IDE data cable & connect the 40GB drive to the next connector of the same IDE data cable. Re-check all power cables & data cables for good connections before closing the case. Plug the power cord in & power up the PC. Everything should run just fine.
Setting the pin for you're IDE drive's can be very confusing. Click on the link below. This will give you an idea of how to set you're pin for a master drive, master with a slave drive. If you post the name ST****** of you're two drives I can post the correct pin locations from Seagate's web site.
