Linux Dd Dvd Input/output Error

2008, 10:57 PMI bought a DVD Movie (Dark Knight) and I want the iso on my computer. I can play the movie in dd copy protected dvd vlc but when I run # dd if=/dev/dvd of=/home/user/Desktop/Bat.iso dd: reading `/dev/dvd': Input/output dd: error reading ‘/dev/sr0’: input/output error error 720352+0 records in 720352+0 records out 368820224 bytes (369 MB) copied, 77.214 s, 4.8 MB/s Since dd is a dd: error reading ‘/dev/cdrom’: input/output error low-level operation, it makes no sense to me that the DVD plays but dd cannot simply read the 1s and 0s from the dvd. jbrown96December 13th, 2008, 11:02 PMThat's a strange device for

your dvd player. Mine is /dev/scd0. Use the same device as listed in fstab cat /etc/fstab I can't remember if dd needs the device mounted or umounted, but you should try both ways. You can always try using Brasero; I'm pretty sure it can make iso's. I prefer using command line tools, but it may be easier to go with GUI app. JohnGalt131December 13th, 2008, 11:05 dvd block size PMThat's a strange device for your dvd player. Mine is /dev/scd0.

It stopped at the same place (369 MB) Also, brasero was the first method I tried.

They purposely "corrupt" the data so it cannot be easily copied to reduce piracy. insane_alienDecember 13th, 2008, 11:09 PM/dev/dvd and /dev/scd0 will be the exact same device, just under two different aliases. /dev/scd0 will be the actual device /dev/dvd is mapped to it because its detected that there is a dvd there. jbrown96December 13th, 2008, 11:17 PMIf I remember correctly, that error comes up when you try to duplicate encrypted DVDs.

I even threw some video DVDs at it to make sure it wasn't the disc. Code: [pickens@acer1 Videos]$ dd if=/dev/sr0 of=POTC.iso dd: reading `/dev/sr0': Input/output error 5088+0 records in 5088+0 records out 2605056 bytes (2.6 MB) copied, 1.67727 s, 1.6 http://forums.fedoraforum.org/showthread.php?t=241604 MB/s [pickens@acer1 Videos]$ I am getting the same thing on my laptop running Mandriva, oddly enough. Two different drives, two different computers, two different distros and multiple DVDs. What could be the problem?? __________________ Desktop machine: Zotac MiniITX MB / Pentium Dual Core E2200 (Soon to be Core 2 Duo), 4GB RAM, 640GB SATA, nVidia integrated GPU.

You will probably run into trouble if you try to install from it. –Rinzwind May 17 '12 at 6:51 Check dmesg for more detailed errors. And if it is a copy protected video dvd then you will need a program to decrypt and unlock it. –psusi May 17 '12 at 14:00 | show 1 more comment 2 Answers 2 active oldest votes up vote 5 down vote accepted If you feel like going terminal you could try this: dd if=/dev/dvd of=/myiso.iso bs=1024 There are other examples here: http://digitalsanctum.com/2007/01/26/how-to-make-an-iso-image-using-dd/ s
