Hi, all.
Has anyone had any experiences using these tape drives? I have one that
works fine under NT, but the following comes up in dmesg, and similar errors
in /var/log/messages when I try to access it. Am I missing something?
I'm using RedHat 6.0, with a 2.2.5-15 kernel.
Thanks

Post the exact error message, not a paraphrase. There are a number of
things that could be going wrong, but without exact info, I'm shooting
in the dark. Anyway:
Have you compiled IDE-SCSI Emulation, SCSI Support, and SCSI Generic
Support as modules or directly into the kernel?
Are those modules loaded? (if you made modules) "modprobe ide-scsi sg"
Did you boot with "hdX=ide-scsi" as a kernel parameter? If you don't do
this and you have IDE CD-ROM support enabled, the IDE CD-ROM driver
will grab your CD-RW and won't let go.
Try those things. If still no luck, post again, giving the exact text
of the error messages you get, as well as your kernel version and the
distro you're using. HTH,

It can. (If my ancient P-150 laptop can handle it, your machine can!)

The shorter the better. UDMA/66 operation requires the dark gray cable
with 80 wires and colored connectors (blue/gray/black). Linux can do
UDMA/66 if your board can; you just need a recent kernel and you may
have to apply a patch + use -X68 as an argument to hdparm.

hdparm -m16 -u1 -c1 /dev/hda works very well for me. I noticed no
benefit to using -d1, but -m16 and -u1 speed things up by about 30%.
FWIW, the 2.4.x kernel speeds disk I/O up by even more than that, from
13.5 M/s to 18 M/s (hdparm -Tt benchcraft) on my system.

Courier can be a disappointment partly because USR has not kept this
great modem updated for late technology. As of today, it still has no
drivers that make it work properly with Win Me (per their tech support).
The price of this modem nowadays, does not equal it performance.
What are you people who have recently purchased Courier modems think?

If I had recently bought this Courier, I would be pretty darn upset,
because as I mentioned in my initial post, my dad's Sportster 56k beats my
Courier, no contest.
If they released new firmware for the modem, it might be pretty decent.
However, I can't complain too much---I got mine pretty cheap years ago
direct from USRobotics when they had their "SysOp deal." Before the
internet took off, and Bulletin Board Systems (BBS) were huge, USRobotics
practically gave their Courier modems to legitimate BBS operators (the
price was less than half of retail I think... $200 maybe?)
Oh well.

Subject: CDD2000 with 2.2.14 -> PC deadlock
Date: Fri, 22 Dec 2000 03:15:24 +0100
Reply-To: [EMAIL PROTECTED]
Hello,
since my last upgrade 2.2.5 (Suse 6.1) to 2.2.14 (Suse6.4)
I can't any longer burn CD's. cdrecord invokes a full
linux-deadlock within about 25 seconds. After keyboard,
mouse, remote login, .. all is dead! I have to turn off
my PC by electric current.
In these 25 seconds I have the chance to logout
from KDE and reboot, that my hd won't
damage. Its very funny: in this case I can reach the
last message of linux shutdown "unmounting /proc"
- an linux is completely locked. But very often
the shutdown is stoped by the deadlock before unmounting
the HD :(( - or I give up shutting down an join the freezing
PC ...
I have tested cdrecord 1.6.1 from suse 6.1 in Suse 6.4. I have
tested the latest cdrecord (cdrecord-1.9a05) - but
all was in vain: cdrecord locks linux totally after about 25 Seconds
I have tested a ATAPI-Writer (Freecom 32x8x4) and cdrecord (Suse 6.4)
works fine.
I use Adaptec-SCSI-Controller 1505. With Suse 6.1 (2.2.5)
all worked well (I just re-installed Suse 6.1 on another
partition an on works well on the same PC).
I compiled SCSI-Support as module or added it directly to the
kernel. Nothing changed.
I can use the writer as CD-ROM by mounting the device.
Okay, it seems to be a software bug within 2.2.14. But
in other newsgroups an mailing-lists I got no help.
I think there is a timout somewhere in the hardware,
because Linux can shut down as fast as normal during
the 25 seconds after starting cdrecord.
Has somebody an idea why Linux locks totally?
Perhaps because of the very old AHA1505-Adapter ?
BTW: WinOnCD (Win95) works fine ...
The writer ist recognised correctly

I just acquired one of these modem cards for a ThinkPad 600X on which I
am running RedHat 6.2 with version2.4.0-test11 of the kernel. The
ThinkPad has a Lucent modem built in, but the binary only driver does
not work in kernel versions about 2.2.14. I am wondering whether anyone
could provide me with any links or advice on configuring this card -- I
have not come across much on the web. Thanks in advance.

The modem's volume control does not have any effect on the volume of the
high pitched sound, unfortunately. Another poster said the noise could be
a result of noisy phone lines. We live out in the country, quite a ways
from the phone company, and our phone lines are horrendous.
However, since my dad's Sportster modem works okay, I am assuming the
phone lines are not the problem here.

We're rural, probably five or more miles from the phone company, and our
phone lines are awful. Five or six years ago I was big into bulletin
board systems, and I was lucky if I could maintain a connection to half
the BBSes I called.
I used to call the phone company daily to complain... one day they
"teased" me by saying that they could install some coils or something to
improve the signal over long distances such as mine. So later when I
asked if they would do that, they said, no, that's too much work, you're
out of luck. Apparantly our phone lines meet the bare minimum quality
standards, i.e. they're good enough for voice conversations, but they
stink for modems and such.

I put this in a previous post, hopefully it should provide some insight!
Thanks a million,

Yes! I forgot to mention that in my original post. The "ARQ" light does
in fact flicker quite a bit. The flashing usually gets pretty intense,
with longer periods of off than on just before a disconnect.

I think that's what I'll end up doing, is disabling v90. I just sent an
email to my ISP's tech support to see what kind of modems are stocked in
their dial-in pool.
Thanks for the info!
