We allow only a subset of standard commands to be issued by unprivileged applications. We don't strictly enforce transfer sizes and its arguable on SCSI transports this doesn't matter one iota. On ATA it perhaps matters a bit more. Note btw - the reset sequence cased by excess data off these drives is something we jump up and down and trigger. For PIO draining the bits is fine, for DMA pretty much all controllers will clean up happily enough. Its also nothing like the problem you might think as most drives told "send me 150 bytes, oh and the transfer length is 40" will in fact send 40.
