As has already been pointed out that is not a Centos Plus kernel. Did you reboot after installing the new kernel? (You have to reboot for a kernel update in order to be running the new kernel). 2. 1 hour to copy 100GB sounds like a very good speed. Obviously the eSATA interface will be the fastest as it will the the same as having it plugged directly into the SATA controller. For reference I recently copied 73GB from an internal SATA drive to an internal (software) raid0 array (made up of 2 SATA disks), and that took 1.5hours. Regards Laurence
