Installing 2 SATA Drives

Hi,

I have an Intel D865Perl Motherboard with 2 serial ATA connectors.

I have 2 serial ata disks, one WD of 80 gb and a maxtor of 120 gb

I want them to be treated as 2 different disks, so I just plug each of them to a different conector in the mother.

Lets call them WD to the western digital disk, MA to the maxtor disk, C1 and C2 to the 2 different connectors

If I connect WD to C1, it works just fine.
If I connect WD to C2, it works just fine.
If I connect MA to C1 it works just fine.
If I connect MA to C2 it works just fine.

If I connect MA to C2 and WD to C1, it appears just the WD one.

Any ideas of why this can be happening?
Note: I've read about plugging them together and using them as a RAID, but that's not what I'm looking for.

Thanks in advance

Check the size of the reported drive.  It may well be that indeed Raid is being used without you selecting it and the drives are being combined into a 200GB JBOD array!!

There is no reason whatsoever why you would not be able to run seperate drives on separate channels.  If you are unable to do this and either 120GB or 80GB is being reported as total usable drive space then you must have a dodgy M/B or the Bios is not configured correctly.  I take it you have tested both of the cables and drives also.

Good Luck

Mike.

Yes, I had tested both cables........

And the problem is that when y plug them both, only the WD drive is detected in the bios.

Any ideas?

Either the bios, but certainly sounds like a faulty motherboard to me.

I have built tons of PC's without any problems, the only problems I have encountered similar to what you mention is motherboard fault.

Are the drives S-ATA or IDE drives with an S-ATA adapter. This could also be the problem if the jumpers are set incorrectly

To tell you the truth Mike, I have no idea what happened.

I unplug all the other ide drives I had and also both of the SATA ones, both energy and data and plug them again (just the SATA ones) and it started working.
I guess it may have been some kind of too many drives for the power source to be able to handle them.

Thanks anyway

No problem, I was just going to suggest that, when I read your post above about the extra IDE drives.

For a modern system with several drives running, I would advise you to run a 350w - 400w minimum PSU.

Anything less could quite well result in problems.

Regards.
