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.
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.
