No. It's a broken bridge that replies to _everything_ with page 6 and doesn't return a header at all - not 4 bytes for MODE SENSE(6), not 8 bytes for MODE SENSE(10), *zero* bytes. Just the page 6 contents. So in place of block descriptor length (offsets 6 and 7) you get the part of page 6 body. Which is going to be bits 31..16 of size in blocks. And that's going to be 0x17bd in his case (203928MB/0.5KB/65536). - : send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
