[opensuse] How do I mount a UDF CD?
All, A client gave me a CD written with a UDF filesystem (I think). I can see the contents of the CD fine via XP. With Opensuse 11.1 / Dolphin I get error messages.
From the command line I get:
mount -t udf -r /dev/sr0 /mnt mount: wrong fs type, bad option, bad superblock on /dev/sr0, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so dmesg in turn shows: UDF-fs: No partition found (1) end_request: I/O error, dev sr0, sector 173316 end_request: I/O error, dev sr0, sector 173312 end_request: I/O error, dev sr0, sector 173316 udf: udf_read_inode(ino 43329) failed !bh end_request: I/O error, dev sr0, sector 173316 udf: udf_read_inode(ino 43329) failed !bh UDF-fs: No partition found (1) What should I try next? FYI: I already have the data accessible by moving it to a thumb. I would still like to know what is going on.

Well, it says there is a read error, and that is probably true. You could try dd_rescue to get a file-image, and then try to mount that instead. Someone commented here a better tool to recover data from recalcitrant cd/dvds, but it seems I forgot to take a note of it. - -- Cheers, Carlos E.

Hi Carlos, While there might very well be a media error in this case, I have also run into the UDF mounting problem. I eventually had to use a Win-XP box to mount the CD, then used Samba to transport the data to Linux. This was more than a year ago and I was probably using a 10.3 system.

Maybe it is a media error. When I try to make a iso via dd, I get Feb 6 13:04:00 tiger3-64bit kernel: end_request: I/O error, dev sr0, sector 1248 Feb 6 13:04:00 tiger3-64bit kernel: __ratelimit: 1 callbacks suppressed Feb 6 13:04:00 tiger3-64bit kernel: Buffer I/O error on device sr0, logical block 156 Feb 6 13:04:00 tiger3-64bit kernel: Buffer I/O error on device sr0, logical block 157 Feb 6 13:04:00 tiger3-64bit kernel: Buffer I/O error on device sr0, logical block 158 Feb 6 13:04:00 tiger3-64bit kernel: Buffer I/O error on device sr0, logical block 159 Feb 6 13:04:00 tiger3-64bit kernel: Buffer I/O error on device sr0, logical block 160 Feb 6 13:04:00 tiger3-64bit kernel: Buffer I/O error on device sr0, logical block 161 Feb 6 13:04:00 tiger3-64bit kernel: Buffer I/O error on device sr0, logical block 162 Feb 6 13:04:00 tiger3-64bit kernel: Buffer I/O error on device sr0, logical block 163 Feb 6 13:04:00 tiger3-64bit kernel: Buffer I/O error on device sr0, logical block 164 Feb 6 13:04:00 tiger3-64bit kernel: Buffer I/O error on device sr0, logical block 165 I don't care that much, so I'm going to let this go as defective media.

Readom which is part of the devd+rw-tools package does seem to be pretty good at recovering data from damaged media. I would after doing some tests, suggest it as a better option for optical media than dd for copying or recovering a damaged image. It is possible to recover usable info from an sector crc check failure which dd does not really handle very well (it seems to just blank the failed sector which makes sense for magnetic media but is problematic for optical media, and there is no obvious way of over riding this behaviour). Optical sectors contain integrity checks. failing such a check does not mean all the data is bad. Different rules apply for magnetic media. BTW I would expect cdread from the original fork which the author claims to be more regularly maintained to be equally useful. - -- ============================================================================== I have always wished that my computer would be as easy to use as my telephone.
