Doing a "hdparm -I /dev/hdc" (without a disk/with a ISO disk/[u]mounted/music CD):
Aug 14 19:14:33 sleipner kernel: hdc: drive_cmd: status=0x51 { DriveReady SeekComplete Error } Aug 14 19:14:33 sleipner kernel: hdc: drive_cmd: error=0x04 { AbortedCommand } Aug 14 19:14:33 sleipner kernel: ide: failed opcode was: 0xec "hdparm -i /dev/hdc" does not interfere (hdparm v6.1) and normal access like copying, burning, playing etc works without that message emerging. Though I have seen it once... During a session of quick mount/umount/play video file of several disks, there it was. I attributed it to bad media. This is a VIA motherboard (AMD64 equipped) and I run without any desktop: root:sleipner:~# cat /proc/pci PCI devices found: Bus 0, device 0, function 0: Host bridge: PCI device 1106:0204 (VIA Technologies, Inc.)
