ASUS K8V-MX Motherboard recognizing 320 GB SATA harddisk. Why?

You can indeed mix IDE & SATA drives on a computer. If installing the OS (Operating System) to the IDE HD, you will only need to instruct the BIOS to boot the IDE HD drive first.

If you decide to install an OS on & boot the SATA drive first; you will need to instruct the BIOS to boot the SATA drive first and may need to provide a driver for the SATA controller - if the OS install does not recognize the SATA drive. The driver should have been included on a disk or diskette with the controller (or on the motherboard driver disk if a built-in type controller). You should see a prompt asking "If you need to install a driver.... press F6" (or similar). Press the F6 key and supply the driver disk - and follow the prompts.

Good luck!

you will need to go to asus website type in that model number to update your sata/ide drivers. BUT FIRST if its connected via a ribbon gray cable (ide) ther eis a white jumper on the back of the hard drive the jumper may be black anyway it needs to be set into slave mode it will be listed on the hd on how to do that LET ME KNOW IF THAT FIXED IT.

Hi,
Thanks for the details. I have used K8V-MX Asus motherboard and found it very reliable with quite reasonable performance. It definately supports 500 GB Sata drive and there must not be any issues after increasing just the storage. However, Operating System upgrade may result in sluggish performance. Drivers dont seem to be an issue to me either.
I suggest to review a few points detailed as under: -
- K8V-MX Asus Supports RAID, so, check for any RAID Drivers/ settings. (You dont have to use RAID for two Hard Drives of different make, capacity and speed). Try using one disk at a time having same Operating System (e.g. Windows XP) and compare the performance.
- Infact SATA Drives have better data transfer rate than IDE, which results in enhanced performance.
- Some Programs (that you may not be using with 80GB drive) Like antivirus may result in decreased performance.
- Please Review you Operating System environment and software installed. Make sure that the new drive & Operating System are free of any virus, which results in CPU Utilization upto 100%.
- Also, motherboard supports Max 2GB RAM, so you may consider adding more RAM.

Let me know if any further clarification/ assistance is required.
Hope it helps! Good Luck!

Yep ...the K8V-MX board has 2 SATA ports ....so no problems there :-)

Here's a link to the full specs:

Hi thun, Unplug the power cable from the PC.
Please reset the bios. This is shown in you're user manual on page 1-17. (If you no longer have you're user manual for the Asus K8V-MX MB you can download it from Asus by clicking on this link):

Remove the SATA data cable & clean both ends of the cable with a few drops of alcohol on to a cotton swab. Than clean both SATA ports on the motherboard using the same method.
Also clean the SATA power connectors in the same fashion. (Allow time for the alcohol to dry).
You can help it dry using some canned air.
Re-connect the SATA data cable & SATA power cable to the SATA drive. (Check all other connections within the PC for good connections before closing case). (SATA data & power connectors are easily knocked loose, so be careful).
Plug the power cord back into the PC & boot the PC. Enter you're bios. Check the main menu & make sure the bios has listed the SATA drive. Than go to Boot menu. Page 2-27, 2-28 in the manual. Make sure you see the SATA drive listed here. If you are sure the SATA drive was listed in the main menu than it must also be listed in the Boot menu.
If it is not listed in the Boot menu than there is a problem with you're bios. You're board is warranted for three years from manufactures date. Please call Asus tech at 1-812-282-2787.
M-F 9:00AM to 5:00PM EST. You will need the serial number printed on a white label located on the pink LPT port. You can see this only from within the PC. Asus will ask for that S/N to determine if you're board is still within warranty. If it is, make sure you get a case number & instruction before ending the call.

Good Luck!
Mike

i also need help
my motherboard cannot detect also my SATA harddisk
my Mother board is K8V-X but in boot options i see my harddisk
but in main menu no SATA..
so thats why i cannot reboot or reformat my pc

Yes, your board will support 320gb. I am not aware of a limit to how many gigabytes you can have per computer. I currently have 1.5 terabytes. 1500gb.
