Esata port not working

[Rilex]

hi,
I connected my external HDD via the eSata port with esata cables on asus motherboard.but the problem is my external hard drive is not shown in device manager.but when i connect another hard drive it works.Everything is working fine except that my e-sata port doesn't seem to be working.

To get eSATA working on an Asus motherboard, you just have to enable "JMicron RAID Controller" in the BIOS. or click on the unknown device and try to update the driver (PCI controller)

Does anything happen at all when you connect it?

Does the computer try to think about it? or does it just not react at all? It is possible that the Port is not enabled. Try downloading the latest chipset driver for your mother board and installing that.

When you plug in the external unit (and power it on) prior to boot, is the drive recognized by the system? That'll tell you if it's an issue with the Sata port, or with the E-Sata config.

You also mentioned that an internal drive works using that port, but does it work as e-sata? (Do you have a "safely remove this device" icon?)
