I currently have 3.o sata mobo. I have 2 other 3.0 sata hd installed working fine. I am trying to add a 3rd. The new one is a segate 6.0. Will this work on a 3.0 mobo. I installed the new hd, device manager pops up and says this device installed correctly with a green check mark. Windows does not recognize it. Bios, and disc management does. It is a 2tb, but disc management only shows it as 3.86 gb. status says not initialized, and unallocated. If I right click on it to initialize it, it is grayed out (not an option). In EASEUS Partition Master, it says read only. Any ideas. Thanks.

It appears that your new drive may be DOA. :-(
If the drive spins up but cannot read its hidden Service Area, then it will identify itself with a factory alias (eg ST_M13FQBL) and a reduced capacity.
