Hi, just in case this helps anyone, wanted to share my experience getting this Toshiba external eSATA/USB drive to work using the eSATA interface with Ubuntu Linux 10.04 Lucid Lynx.

I had to go into the BIOS of my DELL e6400 Latitude laptop and enable the AHCI feature of the ATA, and then it worked perfectly, even auto mounted on boot.

The Toshiba HD is the 2Tb model PH3200U-1EXB (GEN2)

HTH, Gil
