>Description:
Incorrect standby timer values are sent to the disk. According to t13, the values should be:

1-1200 seconds: (seconds / 5)
1260 seconds: 252
1800-19800 seconds: (minutes/30) + 240

Currently a timeout value of 1800s (30 minutes) is being programmed as 242, which will cause the drive to go into standby after 60 minutes.
>How-To-Repeat:
Compare the code on line 4315 of src/sbin/camcontrol/camcontrol.c with table 19 in T13 1532D Volume 1.
