NEW INFORMATION I've tried the same command dd conv=noerror if=/dev/cdroms/cdrom0 of=family.iso on x86 (different machine) and I was able to copy 2.6Gb to iso file; so it stopped in different location. However, in one of your previous email you suggested I try: # mkisofs -o mydvd.iso /mnt/dvdr/ so I did and the system stopped (on amd64 machine) with Input/output error. can not read from '/mnt/dvdr/video_ts/vts_01_0.bup' Following you suggestion ----quote--- Just to flog a dead horse, I suspect that there is indeed some error on the dvd and that it is in the file video_ts/vts_01_0.bup It may be that the error is insufficient to matter on playback (after all, whats a few frames of video between friends, the eye hardly notices it ), but when the computer actually needs a bitwise copy it barfs? ---end qutoe--- That was good suggestion, so I rebooted the amd64-machine (just to make sure not process is left running from previous operations), mounted the DVD: # mount /dev/hdc /mnt/dvdr and I've tried to copy that file 'video_ts/vts_01_0.bup' and I could not, I got Input/output error. # cp: reading /mnt/dvdr/video_ts/vts_01_0.bup': Input/output error However, when I repeated the same process on x86-machine it copied just fine: # cp /mnt/cdrom/VIDEO_TS/VTS_01_0.BUP . # ll total 2759652 -r--r--r-- 1 root root 126976 Mar 16 10:34 VTS_01_0.BUP It copies the same file without any problem The strange part is that when I mount the same DVD in amd64-machine all directory and files are listed in small letters (and I know they should be all CAPS). # ll /mnt/cdrom/video_ts/ total 4211042 -r-xr-xr-x 1 root root 12288 Jan 27 12:37 video_ts.bup -r-xr-xr-x 1 root root 12288 Jan 27 12:37 video_ts.ifo -r-xr-xr-x 1 root root 114688 Jan 27 12:37 video_ts.bob -r-xr-xr-x 1 root root 126976 Jan 27 12:33 vts_01_0.bup ... But when I mount the same DVD on x86-machine it list the directory and files in CAPS as it should # ll /mnt/cdrom/VIDEO_TS/ total 4211042 -r--r--r-- 1 4294967295 4294967295 12288 Jan 27 12:37 VIDEO_TS.BUP -r--r--r-- 1 4294967295 4294967295 12288 Jan 27 12:37 VIDEO_TS.IFO -r--r--r-- 1 4294967295 4294967295 114688 Jan 27 12:37 VIDEO_TS.VOB -r--r--r-- 1 4294967295 4294967295 126976 Jan 27 12:33 VTS_01_0.BUP ... Though, I don't see what difference it could make, but why one machine list the files and directories in small letter and the other one in caps. -- #Joseph -- gentoo-user@gentoo.org mailing list
