Have the same issue with Lucid on Lenovo Thinkpad W500 with external Hitachi HTS72101 0G9SA00 hard drive when copying data from the external drive to local hard drive and vice versa.
This issue highly depends on the hardware combination.
1. other external hard drives like Lenovo secure hard disk 160GB do not show this issue
2. same Hitachi HDD attached to a Lenovo Thinkpad T61p does not have this issue.
