John,

My L20 didn't need anything specific done in order for my L20 to read 
barcodes.  As far as the write errors, are you sure that the drives
are set up properly?  Under Solaris I had some problems until I got
the OS configured to use the drives properly, enabling variable block
sizes.  Before that was done I could write but media would freeze upon
read.  Check the drive manufacturer's manual for the drive for OS-specific
instructions for drive configuration.

Also, ensure that your library has the latest firmware installed.  STK
support should help with that.

Take care,
