lost external eSATA port

lost external eSATA port

[kenneth johansson]

After an error on the external disk the port no longer work with any disk.
When the error happened the /dev/sdx was removed. if I change disk its never recreated.
I get no log output from kernel indicating any type of action at all.

Is there a way to reset the port ??

I have a
Base Board Information
	Manufacturer: ASUSTeK Computer INC.
	Product Name: P5B-V
	Version: Rev 1.xx

board where  I think the eSATA port is controlled by 
IDE interface: Intel Corporation 82801H (ICH8 Family) 4 port SATA IDE Controller (rev 02)
or perhaps 
SATA controller: JMicron Technologies, Inc. JMicron 20360/20363 AHCI Controller (rev 02)
----------
kernel is 2.6.28.7

this is the last kernel log regarding the esata port.

The device seems to have checked out.  Is it a WD mybook?  Can you
please attach full kernel log including the boot messages?

the is no partition on the disk so this is expected.
