Correct.

Quote:I ask because that would explain why I'm seeing status 01 reported - it's read one sector (and the iSCSI side of the logging and tracing suggests this is all fine as well), but for some reason the carry flag is being set, triggering reporting as an error. I'll have to dig into the iSCSI hook to see why that would be...

Try adding "scsi" to your DEBUG= list.
