smartctl not providing disk information

[neilms]

My hard disc is definitely /dev/ada0. If I run [CMD="smartctl -i /dev/ada0"][/CMD] I get: Error sending CAMIOCOMMAND ioctl: Inappropriate ioctl for device'
Then there is a message about specifying device type with -d option.
I have tried everything but can't get smartctl to work. Does this program only work with certain drive types?
Any help is sure appreciated.

Use
# smartctl -a /dev/ada0 | less -S

Are you sure that you have updated smartmontools after some system update?
