That's READ DISC STRUCTURE, an inspection command for DVD and BD media.
It has a long list of Format Codes which request various info sheets.
Many of them applying only to some particular DVD or BD type.

Other than with the command 0xbe READ CD, the sts code is a valid reason
to issue an error message and it is plausible to appear with a CD medium..
"sts 3" is SCCMD_SENSE which indicates that req.sense contains valid bytes.
I'd guess that KEY is 5 = "illegal request". ASC, ASCQ might be 0x24, 0x00
meaning "Invalid field in cdb".

Have a nice day :)
