Re: [CentOS] DVR recorder how to resucue files
dd does not show partitions, fdisk does (or parted or ...). Sorry, my mistake. I used several disktools.

Re: [CentOS] DVR recorder how to resucue files
It looks like you've backuped an entire disk that might contain partitions. So first check if you have partitions inside: sudo fdisk -lu save.dd If you have partitions inside, use the start offset of the partition to create a loopback device (e.g. a partition starts at 56): sudo losetup -o $((56*512)) /dev/loop0 save.dd Now you should be able to use the partition. First check and than mount it: sudo fsck -fv /dev/loop0 sudo mount /dev/loop0 /mnt xxx Hallo, no partions are shown with dd. Found an article that some DVR vendors are using their own filesystems. I think that I ve no chane in this case to rescue anything. Thanks for all hints.

I'd try fdisk to see if there are partitions, first, then if you find anything that looks likely, try mounting that. Also, try the "disks" utility, which also may be able to tell you something about the disk. Good luck!

If this were a normal DVD, you'd have to specify the file system: mount -t iso9660 -o loop save.dd /mnt/backup But you say the DVD uses a non-standard file system, so this may not work. > Tools like parted don t show partions in the bckup-file DVDs don't have partitions, and I don't think parted would work on an image anyway. -- Yves Bellefeuille ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

Tell us what you tried (the exact command) and what happened (any error message). Ok, sorry. Our recoder device that stores all videos of several cameras doesn t work any longer. Before doing anything on the the device or the disk I made a full backup oft he disk with dd. Trying to mount this file simple with mount -o loop save.dd /mnt/backup fails. I found out that VDR are using non-standard disk-configurations and filesystems. So my question if there is a way to get access the files in the image. Tools like parted don t show partions in the bckup-file.

[CentOS] DVR recorder how to resucue files
Hallo, we've a DVD recorder from everfoces and problems to open files using the interface. I made a backup using dd without any problems but how can I mount this image. Normal loop options don't work. Thanks for hints. Ralf ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
