2tb SATA drive compatibility

HI Experts

I have a PC with a Gigabyte GA-MA78GM-DS2H motherboard

currently installed is a 1tb SATA hard drive.

I have purchased a 2nd HD for additional storage it is a

Western Digital WD20EARS 2TB Hard Drive SATAII 64MB Cache

now, I have a problem..... the drive does not appear in BIOS, or windows...

I remove the existing 1tb drive and have just the 2tb drive connected, and still nothing....

I contacted WD, and was told to contact gigabyte about drive compatibility... unfortunately gigabyte are not as easy to contact as WD, and I had to use their email form on the website.... 1 week later and still no reply....

I can't imagine that the motherboard is not compatible with the HD, any ideas where I go from here?

You'll have to look at the mobo specs, but don't forget that there are now 3 different speed settings for SATA.   If your HDD is hardwired to SATA2 speed (3Mbits/sec), but your controller only supports SATA-1 speed (1.5Mbits/sec, or 150MB/sec) then the controller won't see the drive.  So I would check out and make sure my motherboard supports the higher speed, if not see if here is a jumper on the HDD to slow it down to 150MB/sec (same as the 1.5Mbits/sec)

Thanks

the motherboard states that it supports 3MB

"5 x SATA 3Gb/s connectors supporting up to 5 SATA 3Gb/s devices"

It could simply be a bad drive.  Do you have an external USB enclosure you could stick it in?  THis will eliminate both power and your SATA controller.

you can try it on other sata connectors, or on another pc to test
(it can also be the cable - so try another one too)

Thanks guys

I don't have an external housing for SATA drives,

The MB has 5 SATA ports, and I have tried it in a couple.... taking the cable from existing drives which do work (bluray and main HD) but still no joy...

I am thinking it's a dead drive.... (it does power up though)
