command line utility for linux to decode SCSI CDB
Solution 1:
While over a year has passed hopefully this information will help others like me. I dont have a command line utility but I do have specifications which can help.
If your posted CDB is correct then 0x2a is the Write (10) command which means the length of the command is 10 bytes according to Seagate and this is what you have posted.
