I have just bought a second SATA HDD to add to my PC. I need it to run as an extra drive alongside the existing one.

Basically i connected the new drive up, plugged it into the 2nd SATA slot on the MB but the PC does not pick it up - in the BIOS or anything.

I did this with 2 IDE drives once and apart from the fact they need jumpers they just worked straight away.

Any ideas why the SATA isnt being recognised, or even noticed?

Is the drive sata 2 and plugged into a sata 1 connection, if so there could be a jumper setting on the drive to restrict it to sata 1 depending on the make of the drive.

I know maxtor has this jumper.

If you disconect the original sata drive, then connect the new drive to the first sata connection, is the drive found then?

ive tried that. i took the old drive out .. and put the new one in on its own (into the first SATA port) and it still isnt found.

The new drive is a "Hitachi 250GB T7K500 HDT725025VLA380 SATAII 7200rpm 8MB Cache". There are no (obivous) jumper features on the drive whereas my old "Maxtor 6Y160M0" has jumpers.

So its quite possible your motherboard only supports sata 1, if this is the case and the drive has no jumpers then think about a sata 2 pci card.

That could be it. But i have been told by many people that SATA2 drives are almost always backwards compatible, and the HItachi's are the most so.

I just looked at a few specs of the Hitachi Drives and it suggests the whole 7K series is backwards compatible with SATA1 :

Purely depends on the motherboard, my mobo accepts sata 1 and sata 2, a friends only accepts sata 1, his maxtor sata 2 hdd has to be jumpered to sata 1.

so what do i do if the HD has no jumper slots?

Says right at the top that SATA drives operate without jumpers.
