And english is not my native language... Completely reboot your system. The Adaptec SCSI controller will give you a chance to enter its configuration menu and/or its SCSI disk utilities by pressing Ctrl-A. The utilities allow you to scan your disk and to remap the bad sector(s) to good ones. One nice feature of SCSI disks is that they are able to hide bad sectors. UNIX systems are not strong in working with uncomfortable disks ... K.
