I would do this.

0.  What OS are you using?
1.  load a tape into the drive
2.  run `mt -f /dev/nst0 status`  What does this output?  Does it say 
ONLINE?  We need to know this to make sure the Wait_For_Drive() function 
is working correctly.
3.  Instead of sleep, I would increase the wait time in the 
Wait_For_Drive() function from 300 seconds to something higher.  My 
VXA-172 drive can take up to 20 minutes to load a tape. 
 You may want to 
contact the manufacturer, and to determine the maximum load time for you 
drive.
