DVD drive read error while disk is detected / mounted correctly

Asked by Julien Ropé

 I installed Ubuntu Feisty Fawn from its LiveCD, and had no problem with it.
 Then, booting from the hard drive, I discovered that I could not access my CDs (even the LiveCD I made the installation from).
 Every file I try to access seems corrupted. Anyway : I can mount CDs and browse them correctly.

 Details about the configuration :
 - booting from a SATA hard drive
 - DVD drive plugged as Primary master on IDE (also tried Secondary master)
 - DVD drive is a SONY DVD DW-Q120A, having burning capacity

 I tried multiple modifications of FSTAB related to charset, filesystem and mount point. No success in them.
 I finally discovered that the only difference between LiveCD and hard drive installation is that the live CD considers the DVD drive as an IDE device, while the hard drive installation mounts it as a SCSI device. I understand that this is the correct way to make the burner functionality usable, but if this makes the CDs unreadable, I'd rather remove SCSI emulation, and use my DVD as readonly...
 So : my question is : how can I remove SCSI emulation so that my hard drive installation behave like the LiveCD ?
 Of course, if you find a way to ALSO burn CDs, I'm willing to listen :-)

 I run the dmesg command and found the following lines, wich may be usefull to you (I admit that I do not understand that) :

OK.
Anyway, I removed the faulty DVD drive/burner and put a simple DVD drive (not burner) instead, and it works.
It's just too bad that I can't burn anything with Ubuntu...
Thanks anyway.

Closing it since I'm stopping my searches - of course if anybody wants to help, you're welcome.

It could be a cable problem. Recent drives using Ultra-DMA can push data through the cable at high enough rates to expose cable issues.

Use an 80 conductor IDE cable if currently using a 40 conductor IDE cable.
If only using one drive on the cable use the connectors at the ends of the cable not the middle connector.

See this url for more info.

Thank you. Anyway, as I told : I removed the DVD-burner and replaced it with a simple reader.
Moreover, this DVD burner has always worked correctly on Windows, on the same computer, using the same connector... I really doubt it is a hardware problem.

I had this exact same issue in Gutsy, could not copy files from DVD to hard drive.

Solved by changing DMA mode for the DVDRW in the BIOS to UDMA2 (instead of auto)

almost two years later, problems with this drive persist to exist, already on Jaunty
anyone takes care, or ... ?

I agree that it must be a hw problem. I had serious problems with the cables, no matter what os i used. It reappeared now, i'll change the cable and get back.

Also have this problem in Jaunty.

Mine gets a bit weird in that on rare occasions it *does* decide to read DVDs, so I've managed to install some games. And CDs work without a problem.

Same problem on Lucid after ugrade from Karmic.

Strangely cdrom can read some files of the cd/dvd that i put in but, on others of the same cd causes troubles. The cd works fine on other machine with debian and read only drive.
