IBM's position on treatment of MAM when the volume is write protected is 
that if a cartridge is write-protected, Write Attribute command is 
rejected as write protected, 7/27/00.  The sense key should be DATA 
The proposed text ", except for WRITE ATTRIBUTE (see SPC-4)," should not 
be added and Table 5 should list DATA PROTECT instead of MEDIUM ERROR for 
"Processing a WRITE ATTRIBUTE command that would result in alteration of a 
write protected medium."
