Windows 7: External Hard Drive Not Recognized in eSATA

External Hard Drive Not Recognized in eSATA

I have a Fantom Green Drive II, 1TB eSATA/USB as one of my back up drives. I purchased a SATA to eSATA plug for the back of the computer but the drive is not recognized when I connect it up with the eSATA cable. Once I pluged in the USB cable it was regognized and working. Is there something I have to do for it to be working as eSATA, the bus speed is 1500Mbits/sec vs 480Mbits/sec for USB.

Sometimes the eSATA port has to be enabled in BIOS. And some eSATA ports require that the drive be attached and powered on when booting the system. This is particularly true if you aren't running your hard drives in AHCI mode.

To further add to Mellon Heads excellent reply, DELL is definitely one that needs the BIOS set up to activate the eSATA port then once the PC has booted plug the eSATA drive in and it should then be recognized, this is how it worked on my DELL 435T.

The computer recognizes the eSATA port, it even gave it a letter but when I plug the drive in it asks me to insert medium. I think it's either the cable or the drive that's causing the problem. I only use it for backups so the USB will do. Thanks for the help.
