Hello-
I am running RH6.2 (kernel 2.2.18) and am trying to install an external
SCSI Plextor Plexwriter 12/4/32. I have only one other SCSI device (sda).
For the CDRW: termination ON, SCSI ID=4, connected to my SCSI card via
68male HD - 50male HD cable.
My problem:
When I boot up with the drive on, it hangs. My BIOS recognizes the CDRW
just fine but during the boot process, it prints in the upper left corner
"PRESS A KEY TO REBOOT". When I do (and the drive is still on) it gets
stuck in the same place.
When I boot up with the drive off, it boots up just fine but consequently,
my machine does not recognize the drive. 'cdrecord -scanbus' only returns
my hard drive.
I've tried other SCSI IDs but no dice.
Any suggestions? Feel free to respond via email.
thanks
dominic

I have two SCSI adapters: Adaptec 2940, Tekram DC390U2W(sym53c8xx)..
If I do a hot-swap of a drive, how do I get the system/card to
recognize the change?
Thanks!

I'm using a Dakota switch box which is really a rebadged Cybex. It's a
four port box that switches KVM. I'm using all four ports and then
routing the output from the switchbox into a Cybex "Longview" which is
an extender. I've got a 5m CAT5 ethernet cable between the two parts
of the Longview with my keyboard/monitor/mouse plugged into the far
end. This lets me have my four main machines in a different room from
the one that I work in - and given that those four boxes have 4 10k
rpm SCSI drives and 2 7200rpm SCSI drives plus 4 IDE drives and
assorted fans etc - it help keep noise to a minimum. I'm running
various video cards, all of them at 1600x1200@85Hz except the old ATI
card which can only manage 75Hz at that resolution. With this
combination there's the faintest touch of ghosting on some images but
I think that has more to do with the extender boxes than the switch.

You can try the scsiadd utility at http://llg.cubic.org/misc/, within
certain limitations. Heed well the caveats!
If you're trying to manage a JBOD, I don't know of anything better. If
you're trying to manage a RAID array, I'd suggest you get a hardware RAID
controller.

The people at http://www.reiserfs.org have been using a benchmark of their
own creation (the mongo benchmark) to measure performance/stability of a
filesystem. So far the mongo benchmark works only for ext2 and reiserfs.
There's also bonnie++, available at http://www.coker.com.au/bonnie++/ I
believe the ReiserFS developers have been using this benchmark as well.

Subject: IDE error rate
Date: Tue, 27 Mar 2001 20:59:15 -0800
Is there anyway to use hdparm or another program to determin if transfer
errors are taking place on a UDMA IDE drive?
I have two systems with soft raids. Both use the same 81G drives but
I have a transfer rate that is 50% faster over the network on the 4 drive
raid vs the 6 drive raid.
I know that the cable lenghts are at the edge and would like to see
if the promise Utra100 cards are having to resend data or if some other
mechanism is causing the slowdown on the IDE channels.
I found out already that the promise cards seem to be more critical of
cable lenghts than the Intel 815 chipsets IDE controller, I just need a tool
to get more data on it.
The system log showed CRC errors until I shortened one of the IDE cables
but is that the whole story? Can their be correctable errors going on that
the log does not report?
A host of other variables can cause this but looking at the construction,
this is where I feel I need to start.
Thanks

This sounds strangely like one of those subjects that comes out in
testimony years later, where Microsoft applied the right kind of
pressure and had it scrubbed. Try to find an IBM client loaded with

What caveats are there to consider? Both adapters say they are

(Repost. Sorry, the other newsserver died.)
Just bought a Sony 8/4/32 CD-RW unit which will write only at half the
rated speeds even though the media is rated higher. Best Buy won't take it
back after 30 days, I couldn't get a number for Sony CD-RW support (A
12-minute wait for a person in digital camcorders was the best offer I got,
so I hung up), and I didn't even get an acknowledgement of the email I sent
through their website, which has no concept of the term 'troubleshooting'.
If I finally do get through to warranty service (assuming it exists), am I
likely to be just as unhappy about it as I am about the unit?

That's a review, but you should be able to track down the cases
from the info given there. Of course, I'm taking you at your

Subject: 2nd CD-ROM changer not recognized as such
Date: Tue, 27 Mar 2001 22:34:37 -0800
I'm using an old Compaq Deskpro 590 as a Linux-based (RH 6.1) fileserver
for the home. It has two IDE hard drives, and a Nakamichi 4-Disc
internal SCSI changer (ID 1) connected to an Adaptec AHA-1542CF. This
combination works fine, without any tweaking, right out of the box.
Each of the Nakamichi's disks are assigned to a different block device
file (/dev/scd0 - 3) and are swapped automatically, i.e. if I cd from
one mount point to the next, the disk changes.
So far so good. Now I have this Pioneer DRM-1804X 18-Disc changer on
SCSI ID 3. I've tried the selftest that Pioneer publishes, and it seems
OK. But Linux will not recognize it as a changer, and only assigns it
one device file (/dev/scd4). And if I try to mount that device, I get
an error message (something to the effect of "no media") and the Pioneer
doesn't make a peep.
Does anyone have any ideas what could be wrong here? I'm puzzled that
the first changer works without any effort, but the second not at all.
Thanks for any input.
Carsten

Yes. Heat changes fine tolerances. Heat will cause it to completely
crash and die, especially the 10k rpm or faster, but 7200 rpm also loses
life to heat. Fans can get dust in them and die or make noise as well,
be sure any fans in the area are not the real problem.

Hardware acceleration isn't what you want. The key phrase is
"hardware flow control". But you can always check the hardware
compatibility lists on individual models.

I always install LILO on the linux partition and put a third-party
boot menu in the MBR. REASON: third-party boot managers (e.g.,
OS-BS, BOSS, et cetera) can be installed from DOS, or from Windows
in command-prompt mode. So if Windoze wipes out your MBR... you
can fix it without using anything that's inaccessible until it's
fixed.
There's another option: if your Linux distro had you create a
boot floppy (as Mandrake, for example, suggests at install time)
you can use that to boot into Linux, and then you can reinstall
LILO (by running lilo) once you're there.
There may also be floppy diskette images out there that will
let you boot into a small linux with the ability to install
LILO, but I don't know where to look for them.

hdparm -t /dev/hdX give you the speed of your harddisk (IDE)
e2fsck /dev/hdX checks your filesystem
If you want LowLevel-test, then go to the homepage of your
harddisk' manufacturer and download their utilities (normally
they need plain dos). At least Seagate, Maxtor and IBM are
offering quiet good tools.

Subject: Frustrating basic printer service problems! :*(
Date: Wed, 28 Mar 2001 00:22:50 -0800
I posted earlier about trying to print to my Epson Stylus Color ESC P2.
Well, I'm still having this trouble, but I think the problem runs deeper
than just being this specific printer.
As earlier, I can redirect standard out to the device /dev/lp0, but I cannot
use LPR, or any other print function that takes advantage of the standard
print system. I really don't care if I use LPD or CUPS, but I would like to
get either to work period. I read through the chapter on managing print
devices, viewed and edited the /etc/printcap file and all pointers are fine.
Let me ask one thing first.
Should the LPR utility work with printing if your daemon is either LPD or
CUPS? Anyhow, when I try to direct a job to lpr (IE: lptest | lpr) I get
this error: lpr:error - no default destination available. The book goes
over killing and restarting the LPD daemon. What's really strange here is
when typing lpd, it returns to the prompt, but when checking the processes
(ps) it doesn't show up!! What's going on?! I can't kill it if it's not
active. I would expect this is part of the problem. My sd pointer is to
the right existing que /var/spool/lpd/fred.
I would really appreciate if someone here could give me their step by step
instructions for setting up and testing printer services for both LPD and
CUPS! That would help me a great deal to know I'm not doing something
insanely stupid (which wouldn't bother me in the least if I found out I was
doing!).
One other thing. I have the line in the /etc/printcap file for specifying
the standard err log (:lf=/var/log/lpd-errs:\), but why isn't this error
with LPR showing up there?
Thanks once again for all your help.
