Drive: SONY AIT-4 drive SDX-900V series Ver.2.1
Media: AIT-4 (SDX4-200C)
I am using SCSI commands to try and create 2 partitions on a tape (done the same thing before on VXA & DDS drives). The product specification manual implies that this is supported. I have been using the standard Medium Partitions Parameter Page (11h) to try and do this.
BUT.. Mode Sense always reports 'Maximum Additional Partitions' (byte 2) supported by drive as 0. Tried ignoring this and setting IDP bit to 1, Additional Partitions=1 and a valid partition 1 size (as per manual), but this always fails (reports ASC/ASCQ - 2600h; invalid field in parameter list).
I am programmatically (in C++) writing my own data to one of the partitions and then adding a database of the content into the other. I need to know where I can find this database of content, which is why I would normally use a partition. I also want to be able to eject the tape part way through writing, which will cause the DB to be written and then updated later if more data is added.
-Does this drive support creating an additional partition or not?
-If it does then what should I be doing differently?
