My new 3tb WD25EZRX-00MMMB0 ATA is not working at all!

I bought a new caviar green 3tb WD25EZRX-00MMMB0 ATA from a seller through the internet.

I have a 400gb hitachi deskstar 7200rpm that I use as a startup drive with win 7 ultimate 64-bit installed  in it, and I want to use my new caviar green 3tb WD25EZRX-00MMMB0 ATA as a secondary drive. I’ve connected the wires (sata and power) properly and started my pc but the new hard drive didn’t appear in “my computer”. I opened “Disk management” and I looked for it in storage’s tab, and I found that my new hard drive was unallocated !!

I’ve tried “Initialize disk” but ended up having an error message.


And all other options are unavailable


This way I woldn’t be able to use my new hard drive…

My PC has:

-Intel core i5-2500 3.30GHz

-Inte Desktop Board DH67CL

-Gigabyte 550W Power supply

I looked everywere in the internet for a solution to my problem but failed to find any.

Any help would be realy appreciated.

Your Caviar Green is a SATA 6 Gb/s hard drive, try lowering the speed to SATA 3 Gb/s and check if it works. You can also try using another SATA cable or another SATA port on the motherboard. To lower the speed use a jumper on pins 5/6, check the link below for the steps.

Something else wrong-- the size is reported wrong.  Only shows ~2.3 TB.

Should show closer to ~2.8 TB.
