Not TalkingLikeWindows is by definition problematic ...
I hear Windows buffers all the data of each command and never exceeds 64KiB per
command ...
But I too would like to understand where/how the T13 spec requires a drive to tolerate
an indefinite number of arbitrarily placed STOP's.

Subject: [t13] DMA terminate
This message is from the T13 list server.
Hi,
I have a question regarding UDMA protocol.
When a host terminates a UDMA transfer in progress by asserting
STOP, does the IDE drive treat that as termination of command
or does it consider that as a termination of that dma cycle?
In other words after STOP_ assertion will the drive assert a new
DMARQ? Or will it assume an error and update the status register
with the appropriate value.
I will appreciate it, if somebody could point out where in the specification
this scenario is covered.
Thanks,
Steve
