External hdd undetected after plug in

Hi,

I've just bought a SATA external harddisk. The harddisk was not detected once i plugged into my computer or show an icon in my Computer. But I've try with other computer, it works.

Is my computer missing something to perform the detection?

 

And lastly is it partitioned and formatted?

 

Plug unit into computer > Right-Click on My Computer > Click Manage > Click "Disk Management" (May take a minute to load)

Do you see the drive listed here? If so what is the status? Before you continue and tinker here - let us know...

 

Under "Disk Management" The external hdd is not detected. When i bought brand new i'm not sure the guy got partition it..
But I've checked it with other computer under "disk management" and under it's Layout. It says there partition.

 

ANybody help?

 

Crj I would assume it's esata because he says it's an external sata drive but the real question is how is it connected? Do you have an esata port or card and is it turned on in bios if it's on the board and have you tried the pci card if used in another system to be sure it works. You also need to have the right cable for the esata card you know.
