CDROM Power Issues

John,
We are seeing exactly this issue with a Samsung CD-RW disappearing
when running RedHat Enterprise 3WS Linux on a Dell Precision 650n
workstation. The service tag of this configuration is J3LQG41. We
have already gotten a replacement CD-RW and cable from Dell service
but unfortunately this doesn't solve the problem. The problem manifests
itself as an inability to eject the cd-rw tray after the machine has
been booted for some hours. We also see entries in /var/log/messages
of the form...

where the cd-rw is on /dev/hdc and the ATAPI Zip-250 is on /dev/hdd.
Oddly when the cd-rw disappears and stops ejecting, the Zip-250 drive
still functions properly. So far we have always noticed the disappearance
of the cd-rw to occur without media in the drive however we typically don't
leave media in the drive. As to power management settings we are using
whatever the default RedHat Enterprise 3WS Linux settings are and whatever
the BIOS factory defaults are. If there are any changes we should try to
those settings please let us know.

ps I believe the scsi-ide driver is in use for the cd-rw since /dev/cdrom
is a symlink to /dev/scd0. I mention this because all the kernel errors
refer to /dev/hdc instead. Also early in the message log at boot I see...

Lastly I would note that the drive is initially fully functional and can burn cd-r's
but that only after a few hours does it disappear.

John,
I believe we finally have a resolution of the CDROM Power Issues
on our Dell Precision workstation. Dell support sent us two different
Samsung SW-252S CD writer drives to try and neither unit resolved the
issue of the drive disappearing. Both had the same firmware, R901,
as the original drive however. Finally we were sent a replacement
Hitachi CD writer instead and that seems to be working fine. Sure seems
that Samsung has some severe problems with their drives.

Here are some more specifics from one of the machines:

Svc tag: 70Z9R41

Optiplex 170L

Mandrake Linux 10.0 (2.6.3 kernel)

This occurs with the power management set on either S1 or S3 (the only available settings)

The drive is the only drive (the master) on the secondary IDE bus.

It's been occuring with no CD in the drive (though we haven't been leaving CDs in the drive to see if it happens with).

The drive cannot be ejected (with soft eject or the eject button) and cannot be accessed by the OS.

Here are typical system logs:

Jun 4 09:12:37 #### kernel: hdc: irq timeout: error=0x00

Usually the above is all we see, but on at leqast one occasion, we got this immediatly after:

I forgot to mention...

This can occur after being idle for as long as a day, but I've seen it happen as soon as 15 minutes after rebooting.

Tom

Jack,

I'm so glad to see your post. We have the exact same issues with Optiplex 170L machines and these SW-252S drives running Mandrake 10.0. Our system logs (the IDE timeouts etc) are almost identical.

We have 80 of these here. Of the 30 or so we've set up, all the drives have done this.

Tom

Hello all. I have a Precision 360 that my company purchased less than 2 months ago. I have started to notice that after I've had it on for a while, the dvd player and the cd burner both will stop working. It always seems to be when I'm using Internet Explorer that it happens. I get the unplug or eject hardware box popping up and says that the following 2 drives are no longer available. I'm almost positive Samsung appears in the box. I'll have to reboot and verify. The timing is random. It may happen in 15 minutes, or may be ok for several hours. At first I was confused, but now I see that I'm not the only one having issues.

If anyone has any suggestions as to what my next step should be, please let me know. I haven't called Dell yet, but I suppose I should sometime today.

 

Thanks

Russ

If you look towards the end of this thread:

http://forums.us.dell.com/supportforums/board/message?board.id=oplex_cdrom&message.id=4105

...you'll see a link to new firmware R902 for that SW-252S drive. According to it's description, it's supposed to address this issue.

Tom

We have the same problem with a Precision 360 and a Samsung 252S cd-r/rw drive.

We use a screen saver without any other power management. The drive disappears and the eject button doesn't work.  There wasn't any media in the drive when it disappeared.

I downloaded the firmware upgrade for the samsung,as suggested, and it worked. I haven't had any issues since. When you go to use the patcher tho, it's a little tricky but easy to figure out. I'm sure it'll solve your issue.

I removed the drive from a Precision Workstation; installed it in a Dimension 2400 and updated its firmware. Since then,  I haven't had a problem.

So does this R902 driver update fix things or not?

http://support.dell.com/filelib/format.aspx?releaseid=r79594

Does it void warranty?

 

Update 7/27/04

The PC has been on with no problem for 5 days straight after the driver update.  The driver update seems to have fixed it.

I am having the same problem with a Sony CD-R/RW CRX160E on a Precision 530 (DR7NR01.)

I don't have any power managment settings set, the time varies, I haven't tried it with media in the drive and I have one other NED CD/DVD ROM and it goes out when the Sony does (if I remove the Sony the NED works fine.)

When it first started happening (this morning) I was getting the improper ejection of hardware mesage for both CD drives.  Now, it just stops working.

I saw the fix for the Samsung models, is there something similar for the Sony?

 

 

1. What is your Service Tag? 52dcm41
2. What system type are you having this issue with (350, 360, 450, 650, etc)  Samsung SW-252s CD-RW and DVD-ROM drives.

3. Are you using any power management settings?  NO
4. How long do you leave the system on before the issue is seen? Immediately upon boot (WinXP, uninstalled SP2 to see if that was the problem but it's not)
5. When this happens is there media in the drive? Not anymore
6. What extra hardware have you installed? NONE
7. If the drive is no longer seen in the operating system are you able use the ejection button? Yes. 

Drives would disappear randomly after the PC being on for awhile, but a reboot would fix it. 

Now, it happens immediately upon reboot.  Drives show in Device Manger, but with "!" and they cannot be used.  Tried uninstalling/Hardware search, same thing, immediate "!" 

When I try to run the Firmware pasted in this thread, it tells me "Drive Cannot Be Found."
