cygwin1 troubles

[Adam Shepard]

Hi,
 
I'm trying to use 
cygwin1 with tape/tar support with a SCSI Quantum DLT tape drive running under 
NT 4.0.
 
tar tvf 
/dev/rmt0
 
will list 
the contents of the tape (a tar archive), but when I try to extract or list 
specific file names, as in 
 
tar xvf /dev/rmt0 
file1.bz2
tar tvf /dev/rmt0 
file1.bz2
 
for files that are 
on the tape, the tape just reads to eot and then rewinds.
 
output of mount 
is:
 
Device           
Directory           
Type        
Flags tape0            
tape                
native      
text!=binary Tape0            
/tape0              
native      
text!=binary tape0            
/mnt/tape           
native      text!=binary \\.\tape0         
/dev/rmt0           
native      
text=binary d:               
/d                  
native      
text!=binary c:               
/c                  
native      
text!=binary C:               
/                   
native      text!=binary
 
Any ideas as to what 
I can do to get the files off this tape?
 
Thanks.
