Things look quiet here. But I've been doing a lot of blogging at
dan.langille.org because I prefer WordPress now.
Not all my posts there are FreeBSD related.
I am in the midst of migrating The FreeBSD Diary over to WordPress
(and you can read about that here).
Once the migration is completed, I'll move the FreeBSD posts into the
new FreeBSD Diary website.
My thanks to Pav Lucistnik for his help in understanding the problem and working with
me to get things running.
It was a holiday Monday in Ottawa, when it was decided that it was time to move the rack to the other side of the basement.
The goal was to make more usable space. It difficult to get the rear of the rack, and to the shelves behind the rack.
The idea was to swap the rack and the shelve, rotating both 90 degrees in the process. I knew I'd have to move some
cables. When it was first suggested that I move the rack, it was about 1:00 pm. I said it'd probably take 5 hours to move
it. I wasn't wrong. There's still a few things that need to be set up, but for the most part, the LAN is up and running
and everything is in much better shape than it was before.
I took the opportunity to give each machine a thorough cleaning, getting rid of all the dust inside and on the
fans and power supplies. It was then that I [re]discovered that one of my lesser used machines contained a CD-RW.
I moved it from that machine to polo and removed the dead[?] DLT drive that had been sitting there unused
since I started having trouble with it and moved to an external DLT drive.
How FreeBSD sees the drive
The machine named polo is my work horse. I do all my FreeBSD Diary, FreshPorts,
FreshSource, BSDCan, etc, work on that computer.
It is running FreeBSD 4.11 STABLE. That sounds old, now that FreeBSD 6.1 is out.
When I first booted up the box with the CD-RW in the system, I found this:
Pav said I should now be able to see the CD-RW as a SCSI device. I started searching:
# camcontrol rescan all
Re-scan of bus 0 was successful
Re-scan of bus 1 was successful
Re-scan of bus 2 was successful
Re-scan of bus 3 was successful
Re-scan of bus 4 was successful
# camcontrol devlist
<QUANTUM DLT7000 1E48> at scbus0 target 8 lun 0 (pass0,sa0)
<ADAPTEC RAID-5 3A0L> at scbus1 target 0 lun 0 (pass1,da0)
I have highlighted the BURNFREE in bold. The drive supports it, so I'll add it to the command line.
The first burn was with this command:
# cdrecord speed=52 dev=6,1,0 driveropts=burnfree 6.1-RELEASE-i386-disc1.iso
cdrecord: No write mode specified.
cdrecord: Assuming -tao mode.
cdrecord: Future versions of cdrecord may have different drive dependent defaults.
cdrecord: Continuing in 5 seconds...

Turning BURN-Free on
Track 01: Total bytes read/written: 529784832/529784832 (258684 sectors).
That was very fast! You'll notice that I used speed=52. The drive has
52x24x52x written on the front of it. Hence, the writing at 52x.
I took that CD and booted from it using another system. Up came the FreeBSD 6.1 install,
no problems! This is good! Now I have two CD-RW drive I can use.
I bought my first CD-RW back in October 2000, I was advised to buy SCSI because IDE could often not keep up with the
burn process. Obviously, things have changed since then. Not only are IDE CD-RW cheaper, they appear to work just fine.
