I just forgot that INQUIRE is not the correct SCSI command. These are the MODE 
parameter (MODE SENSE & MODE SELECT). For NW cdi_get_status is  the right 
command. 

Here is the example (of course you must load a cartridge first):

D:\>cdi_get_status -f \\.\Tape2147483645
CDI_GET_STATUS returns:
DRIVE_STATUS_READY
current density code = 44
position is absolute block number 1

D:\>

Now you may ask EMC about the density codes ;-)
