Too short SCSI commands?

Came across this interesting filesystem on Aminet and decided to try it out with diskimage.device:
http://aminet.net/disk/cdrom/CDDA-FileSystem.lha

But as can be seen from this screenshot it sends out a READ CD MSF (0xb9) command that is only 10 bytes long while according to MMC standard this command should be 12 bytes:


Is this a bug in the filesystem or should I handle it in the device in some special way (like treat the last two bytes that are omitted as zeros?)?

is only this filesystem affected?
is there anything other commands affected like this?

I would definitely ask more questions before writing a workaround
any workaround may introduce an unwanted bug...obviously?

It's the only filesystem that I know of that sends malformed READ CD MSF commands like this with HD_SCSICMD. The AmigaOS 4.x CDFileSystem sends correct READ CD MSF commands and works perfectly with diskimage.device.

This is pretty much why I started this thread. Would be nice to get an answer from someone who is more experienced than me with SCSI command interface.

Probably should not be replying. Not my forte.

Since the program caters to 5 file systems, are you sure you are looking at ATAPI?

Or, do any of the other file systems use 10 bytes for
the b9 command?
