DVD and BlueRay disks are inherently "digital data" devices with the contents contained in files that are named according to strict standards. (This is very unlike audio CDs.)
this is true. yet, saying dvd distinguishes cd from dvd. plus, i would use *optical disc storage medium* instead of _devices_ for better description, and call what they are accessed in _devices_. :=)
There are a huge variety of wasy that manufacturers of DVD/BR discs use to try and prevent "unauthorized" copying of their products. The most common is the dvdcss encryption of file contents. Some try encrypting even the file names, and several use intentional errors in unused files or parts of discs.
very true.
dd-rescue is just one of many alternative commands to allow copying of such discs.
agreed. i have 3 different releases of dd-rescue that i will be using to try to recover boot tracks of 3 hdd's that that an attempted install of fedora 17 corrupted when i tried to install it. format instructions where pp, to be terse. i did make a 'dd' of each hdd's boot track. problem is that i was distracted before i copied them off to usb memory. and did not. :=( i also have releases of sysrescuecd, photorec, and another recovery prog that idnrc at this time. if you have some advice on such, i would greatly appreciate. you can write me _off_list_ or start a _new_thread_ so as not to ravel this thread. later. -- peace out. in a world with out fences, who needs gates. sl6.3 linux tc.hago. g . -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
