Hi,

I recently purchased a 300GB USB external HDD, However when I plug it into a Linux machine I am unable to mount it the /var/log/messages shows the following:

Jul 16 13:25:56 localhost kernel: usb 4-6: new high speed USB device using ehci_hcd and address 12

When I plug it into a Windows XP SP2 machine it says the device has been found and is ready to be used when I goto
"My Computer" I am unable to see the external HDD and when I goto the disk management utilitys I am unable to
see the external HDD.

It does look like the disk is bad, but the problem is that USB disks can't be properly diagnosed. It is best to remove the disk from the USB case and connect it to an internal connector of your PC as a 2nd drive. Then get the HD manufacturer's utility and use it to test the disk. Most of these tools are included on the UBCD.
