Re: Not recognizing hard drives

This motherboard only supports SATA 1 and is not good at the step back feature that SATA 2 has for backward compatability.
If you have SATA 2 drives, see if the your drives have a jumper to set the to 150Mbps transfer rate for backward compatability with SATA 1.
If you have SATA 1 drives or PATA drives you may be dealing with the partition/format problem mentioned above.

Re: Not recognizing hard drives

It sounds like your hard drive might not be formatted.  If the hard drive supplied a utility to do this you might try it.  If not you can do it through windows xp.

There is a link to some basic instructions of how to format the drive in windows.

I am using K8S MX Motherboard with OS-Windows XP. but my hard disk is not working. i want to purchase a new 160gb IDE hard drive. please tell me if it supports 160gb hard drive or not

The specs for this motherboard say it has a Utra-DMA 133, and 2 SATA 3Gbs ports.
You can connect any IDE HD, and any SATA 3 or lower HD. These standards are backwards compatible. When it comes to size, there is a 2TB MBR limit.
I would skip IDE and go directly with a SATA 3 drive.

Check your AHCI (or ACHI, can't remember) settings in your BIOS. Turn them off, use "standard pata mode" even though you're using a SATA drive, and try again.

ASUS K8S-MX Motherboard, but when I connect IDE

How were the partitions created on the SATA? Are they RAID configured from the other system? Does the new motherboard have the same support for your HD as the other system? Check the setup in the BIOS screen on both systems to make them identical as much as you can. According to Tom's Hardware: "In the SATA port configuration place you have up to four "mode" choices: IDE (or PATA) Emulation, native SATA, AHCI, or RAID." Check this section.

this motherboard does not support your new Hard Drive. SATA is a connection type required for your hard drive. Your motherboard supports IDE connector. You probably can get a pci card that allows you to attach the hard drive.
