SCSI tape data loss

[Matthew Jacob]

Of course linux has async && buffered. Linux has to copy the data from
user space to kernel buffers and *then* write them. This leads to an
obvious desire to overlap such writes. The same feature was available in
Solaris 2.5 as well.

'Buffering' as we talk about here typically means the device buffers
themselves. You don't want to turn this off. You don't want to turn this
off. You don't want to turn this off. The only device that I know of
that really *has* to have this off is the old M4 1/2" reel drive because
it would discard buffered data when it saw the early warning marker.

I have a longer answer to the previous mail about to go out.
