Good day.

Some time ago I posted here a problem description.

========
I've encountered the following problem using Seagate STT20000A Hornet
Travan 20Gb streamer (IDE, Travan 5, connected to primary IDE controller
as slave), tape "Imation Travan5", under FreeBSD 3.3-RELEASE.

Performing
#dump -0uc -d 67733 -f /dev/rwst0 /
causes the following to be output by dump:
[...first portion skipped, it looks like normal dump work...]
DUMP: DUMP: 25933 tape blocks on 1 volume
DUMP: finished in 68 seconds, throughput 381Kbytes/sec
DUMP: level 0 dump on Wed Oct 11 16:51:37 2000
DUMP: closing /dev/rwst0

On this stage, IDE controller hangs.
The following is displayed on the console:

wst0: 26542080d total bytes transferred
atapi0.1: controller not ready, status=c0 <busy,ready>, error=c0
atapi0.1: controller not ready for cmd
atapi0.1: controller not ready for cmd
atapi0.1: controller not ready for cmd
wst0: Sense media failed
========

I found a workaround for this, yet I don't understand how to work with
this normally. The workaround is to create dump on filesystem like

#dump -0uc -d /usr2/dump /

and then copy it to tape with cpio

#echo "/usr2/dump" | cpio -o -F /dev/rwst0 -C 32768

Does anybody know what is the difference between dump and cpio in
their work with tape writer /dev/rwst0 ?

PS. I heard no response. Is this letter visible to others?
