I have a ASUS P5RD1-VM Mother Board and i am install a new 500gb sata hdd so when i install xp a error message appear hdd not found how to solve this problem

You need the original cd from this product to install... i have it when i buy this pc (not new/second)

I have been there too...
But i heard from Indonesian people, they use cloning (clone OS) using Norton Ghost...

Have a nice day ;)

Yes, it's compatible with the motherboard, no, it's not compatible with the XP install disk because it doesn't have SATA support. And since Asus doesn't provides it special driver needed (one that must be put on a floppy) it means that you simply cannot install XP on this disk.
All you can do is to obtain another PATA hdd what ever its size and install XP in it. Then put the new SATA disk in and use it to store all the installed programs and all your files on it. As a bonus you won't lose them if the new PATA disk fails or XP gets corrupted.
Or install Vista or 7 instead of XP, the have support for SATA disks

It's likely a problem with your connection cable from the HDD to the motherboard. The bios shouldn't have to be set up for the HDD to be recognized through a sata port.

The Windows XP installation CD does not include a SATA driver.

If you're using a scsi card and connecting the hard drive to the card you need to have the scsi set-up floppy disk. When the blue screen starts during windows installation watch the bottom of the screen. It will tell you to press F6 key then to insert the floppy disk.
If you're using a sata drive connected directly to the motherboard (not in a raid configuration) you shouldn't need anything but the windows disk. The motherboard drivers and utilities disk should have the files to create the scsi install disk.

Hi
You should find the drivers you are looking for on the Asus website.
Here's the link to their download page,

The motherboard will support this drive.

I will assume you simple need it as additional storage set up as an additional drive?

If you do not see it in My Computer after connecting power and SATA cables, you will need Activate the Drive and Format it

To do this go to Control Panel - Adminstrative Tools - Computer management - Storage - Disk Manangement

You will see the harddrive here, right-cick it, Activate as a simple Partition and then format it.

You will now see it in My Computer and will be able to store on it.

In the motherboard CD, there's an option to create a raid diskette on the tabs above.

Do you have previous Seegate Harddisk or SATA one?

If the SATA is installed previoulsy then it is not to much difficult to install a new SATA HDD. But if you are trying to install Sata on Seegate HDD or in combination then it can not be done.

Let me know in either case, with more detail as you can provide here (For OS, Hardware Specification etc)

Thanks

Things need to be turned on in your bios patrohi. This is why windows didn't boot to the SATA. You need to use your manual & make sure the, Serial ATA Controller is [Enabled]
Within the Advanved menue under SouthBridge Configuration.
At the Main menue the SATA drive should be listed.
Boot settings need to change as well. At Boot Settings Configurations. Make sure your SATA drive is listed.
Boot order should list like, Floppy 1st, CDROM 2nd, SATA 3rd. The SATA will not list as a SATA but the model number of the SATA drive. Once all these settings are set save & exit. Your drive should show up for work & the windows CD should load.
