One disk shown as two in gsmartcontrol

[Leslie Jensen]

I'm configuring smartd on a newly installed system, 9.1-RC3

The message below is in my /var/log/messages


Nov 15 14:39:49 blj01 kernel: ada0: <Maxtor 6B300S0 BANC1G10> ATA-7 SATA 
1.x dev

Nov 15 14:39:49 blj01 kernel: ada0: 150.000MB/s transfers (SATA, UDMA5, 
PIO 8192
bytes)

Nov 15 14:39:49 blj01 kernel: ada0: Previously was known as ad18


Using the GUI gsmartcontrol shows two disks but it's the same disk shown 
as ada0 and as ad18.

I use the following string in /usr/local/etc/smartd.conf

/dev/ada0 -a -o on -S on -s (S/../.././11|L/../../6/15) -m name at mail.server


Is this normal behaviour?
