/dev/disk/by-id/has entries mapping to the drive as well as partitions: 1021% ls -l /dev/disk/by-id/ata-ST3750330AS_9QK0X03V* lrwxrwxrwx 1 root root 9 2010-08-16 10:44 /dev/disk/by-id/ata-ST3750330AS_9QK0X03V -> ../../sdb lrwxrwxrwx 1 root root 10 2010-08-16 10:44 /dev/disk/by-id/ata-ST3750330AS_9QK0X03V-part1 -> ../../sdb1 So you should be able to point hdparm at a udev-managed symlink. -- Brad -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
