I've heard from some people that there was a 2TB limit on SCSI devices, but it wasn't clear to me if this was a limit of the SCSI implementation they were using, or if it arose from the SCSI spec. What's actually the case here?
The group 1 SCSI read/write command descriptor blocks have only a 32 bit field for the device address (block number).
2^32 * 2^9 = 2^41
The group 4 SCSI read/write commands defined in the not-yet-published SCSI Block Commands-2 (SBC-2) standard have a 64 bit field for the device address.
