I have an old PC here and I want to check the HDD. I want to read it once completely into /dev/null. While doing this I want to see the speed.

Because the PC is old I couldn't boot a recent Debian version.

But I got Knoppix running. There is a lot of stuff on the CD but unfortunately dd does not support the status=progress option (because it's old) and pv is not installed. Any ideas?

Knoppix version is 3.2.

  • Try sending signal USR1 to the dd process: kill -USR1 $PID – Panki Feb 21 '23 at 16:28
  • @Panki Yes that works. – zomega Feb 21 '23 at 16:35
  • Lots of Debian and other distros archives on the net: you could simply download a dd/pv binary and run it. Also, if I remember correctly Knoppix contains GCC which allows to compile applications. – Artem S. Tashkinov Feb 21 '23 at 17:06
  • @ArtemS.Tashkinov Of course. But sending signal USR1 to dd is much easier. – zomega Feb 21 '23 at 17:11
  • pv -petrab looks/works so much nicer :-) – Artem S. Tashkinov Feb 21 '23 at 17:14
  • @ArtemS.Tashkinov It's not that easy. When I download a binary for pv it won't run because Knoppix is too old (libraries + kernel). And when I download the source I can't compile it because my system is too old. I'd have to find a version which runs on Knoppix 3.2 and that is not an easy task. – zomega Feb 21 '23 at 17:17
  • If your version of Knoppix has badblocks you might find that more useful to check your HDD. – Stephen Kitt Feb 21 '23 at 17:18
