There are standard SATA host controller interfaces available today which have the capability of reporting different port capabilities/limitations (external/internal, hot pluggability, etc...). With that understood, it should be rather straightforward to understand (through SW) what capabilities are available on a port which a device in question is connected to.

This message is from the T13 list server. Some of the issues do exist today, but eSATA HDD can just make them even bigger(like security). Some of issues are controlled by OS today, for instance, you can not boot from a USB device. But, It will be absolutely unacceptable if we can't boot from a (e)SATA HDD since there is no standard way to tell which port is a internal or external SATA port on a SATA controller chip today in the spec.

Why is an external SATA (aka eSATA?) any different than an external USB or 1394 hard disk drive? -- Hale Landis -- [EMAIL PROTECTED]
