SATA drive visible ONLY after reset?

[loboom]

Hi all,

I've got Epox 8KRAI motherboard. I recently bought a Samsung SpinPoint P120S 250 GB (SATA II, 8MB cache, NCQ) hdd.
I installed Win XP on that drive using the SATA drivers from the floppy disc that comes with the motherboard.

And now here is my problem:

When I power up the system the bios didn’t detect any SATA hard drive.
If I hit reset, then the bios detects the hard drive and everything goes ok.
This happens every time I power on my computer. After a reboot the drive is always visible without any problems... However at the first boor after the power on, my sata hard drive is never detected.

In my bios configuration I've got VIA SATA IDE RAID option enabled. When I disable it SATA drive is not detected even after a reboot.

Anyone have a clue?

Best regards.

can it be jumpered to sata 1

some via raid controllers cannot cope with sata 2 drives

at the initial negotiation bit

Sounds more like a weak or failing PSU; if its possible see if the problem with the hdd reoccurs in a different machine.

wonkanoby was right.

VIA8237 chipset doesn't support SATA2 3Gbps hdd, so I limited transfer speed to 1.5Gps and it works fine so far.

Thanks guys.
