Hi,
I installed my knoppmyth system with an old cd-rw drive and everything was working fine. Then, I wanted to replace the old cd-rw drive by a new DVD player I bought but it doesn't seem to work. When I put a cd or dvd in the new drive it doesn't mount and I can't access it with mythmusic for instance.

Also I can see these errors in the system log:

Nov 1 22:56:41 mythtv kernel: hdc: command error: status=0x51 { DriveReady SeekComplete Error }
Nov 1 22:56:41 mythtv kernel: hdc: command error: error=0x54 { AbortedCommand LastFailedSense=0x05 }
Nov 1 22:56:41 mythtv kernel: end_request: I/O error, dev hdc, sector 0

I think that Knoppmyth is detecting the hardware and configuring the system only while the installation process. Is there a way I could rerun the hardware detection to install my new dvd-rom drive without reinstall the complete system?

The DVD-ROM drive should work without changing anything (exept maybe an extra symlink of /dev/dvd to /dev/hdc, but that's optional).

Perhaps the new drive is faulty, doesn't accept DMA (or requires it) or the master / slave / cable select jumper is set incorrectly.

The last is the most likely. It's worth double checking it and set it properly. I would avoid using cable select and only use master / slave.

Yeah, if you didn't connect the new drive so it appears in the same "place" as the old one that could be it. Try running the cd_link.sh script as root and see if that fixes things for you.

Hi tjc,

I alway seem to jump in questions you have to answer. (Should I stop asking you?)

I have the same problem the thread describes (upgrade from old CD to a DVDROM - remember? I am the guy with the PC without onboard-modem.) My z25...cd.rules only shows the CD entries.

I cannot find the cd_link.sh-script in my R5E50 installation.

Hi,

Just as a stupid question, did you check the rom drive jumper and cable connector? I would think it should be on second port, probably connector closest to mother for hdc and end one for hdd with jumper set for master.

HI Mike,

mother says, there are no stupid questions. But the cables and jumpers are ok. Strange things are going on betwenn heaven and earth.

Hi

You are being kind It could be a defective drive although I do doubt it. I did have one situation where hardware things just didn't work, then as a last shot I popped on a new 80 conductor cable and suddenly all was right with the world. I can only assume it needed the shielding.

What is yur hardware line up? Maybe it will ring a bell with someone and help provide the magic plug.

A collegue was at the CEBIT yesterday. He is not hardware pro or even semipro, but maybe it was inspiring

Did I already write, that the DVD device is recognized as /dev/CDROM? I can mount the filesystem. I just can´t play DVDs.
