Haha. I solved the problem. The error is because I set the wrong major/minor device id for /dev/hde.
Follow the result given by /proc/partition major minor #blocks name 33 0 2000880 hde I create nodes /dev/hde, /dev/hde1.2.3.4 by setting majorid=33. This time: # fdisk /dev/hde hde: dma_timer_expiry: dma status == 0x61 hde: DMA timeout error hde: dma timeout error: status=0x58 { DriveReady SeekComplete DataRequest } ide: failed opcode was: unknown hde: DMA disabled PDC202XX: Primary channel reset. PDC202XX: Secondary channel reset. hde: applying conservative PIO "downgrade" ide2: reset: success Command (m for help): m Command Action....
