Ubuntu – get ‘HDIO_GET_IDENTITY failed’ message when booting with external usb hard drive


I've installed Ubuntu 11.10 on an external USB (2.0) Hard Drive (/dev/sdb1) but when Ubuntu starts I get a message that says:

ata_id[279]: HDIO_GET_IDENTITY failed for '/dev/sdb': Invalid argument

where I made a mistake? The first HD contains Windows 7 (the official OS of my packard bell notebook).

This is a warning from hdparm as it can have problems communicating with external usb hard drives, so you can ignore that warning.
