2 SATA ports not reading device

i have a new Dell 531 that i didn't even realize was SATA until i just added a second HD - i'm not familiar with this type of MB (not sure what kind i have, actually) but i have a problem, i think. the original HD is a Western D and the new one is a 500G Seagate; the generic DVD=/-RW is also connected SATA, and i'm only able to get my MB to see 2 devices, in ports SATA0 and SATA1 (it sees my two HDs as Masters 3 and 4 ??? if they're in 0 and 1 and if i replace one HD with the DVD ROM then it sees the HD and the DVD...).

There's no info in the Seagate docs on how to place the jumpers, but i don't think that's the problem since it's the ports 2 and 3 that are not being seen.

there's no reason to think that the MB has gone bad...

can anyone please help?

This sounds like the SATA IDE Emulation issue.

In reply to: 2 SATA ports not reading device

No jumpers on SATA save that one the cuts the speed so don't waste your time on that.

But are you aware that in today's machines they emulate IDE when you connect with SATA to make it easy on today's techs and builders? That is you may have to catch up with what your motherboard is doing.

Many BIOS's have this feature and some limit to 2 devices in the emulation. Some do 4 but it all comes back to the BIOS, motherboard and OS drivers.

thanks much - my MB is an ASUS M2N61 - what do you mean "catch up" with my mb? what would i look for in the BIOS? i've looked through it once and didn't see anything obvious.

there are only 4 SATA xtions, no other means of connecting devices - surely i'm not limited to 2??? (they're colored Blue, Black, White and Black from 0 to 3, incidentally... for some reason...)

By catch up...

In reply to: thanks

I mean that the knowledge we had for IDE is almost worthless here. Time to catch up to what SATA is.

-> Look in you motherboard's manual about enabling those other ports and if you have elected to run without the SATA drivers for your OS you'll have to see if all the SATA can be IDE emulated.

I don't duplicate manuals or web content but note the issue or topic so you can dig in the right spot.
