Dear all I just updated the kernel of my SuSE 8.1 (from 2.4.19 to 2.4.21). All went well. Verifying the boot messages I saw, among the others, these lines: ... ... hde: task_no_data_intr: status=0x51 { DriveReady SeekComplete Error } hde: task_no_data_intr: error=0x04 { DriveStatusError } hde: task_no_data_intr: status=0x51 { DriveReady SeekComplete Error } hde: task_no_data_intr: error=0x04 { DriveStatusError } ... ... hdf: drive_cmd: status=0x51 { DriveReady SeekComplete Error } hdf: drive_cmd: error=0x04 { DriveStatusError } hdf: cache flushing failed. disable write back cacheing for journalled file systems hdf: drive_cmd: status=0x51 { DriveReady SeekComplete Error } hdf: drive_cmd: error=0x04 { DriveStatusError } ... ... My two HD are on third IDE channel (hde-> third master - hdf -> third slave). What do those lines mean? The system seems to work fine, however. Bye emilio
