Undelete on untouched partition
I have a disk with one single slice and one partition: ad1s1d. I used move to move ALL data on this disk to another location and after that has the disk been unused. Is there a way to get the content back using a copy of a FAT or similar? ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

Thanks for your answer. Is anyone aware of an approach to get some kind of soft deletion functionality on freeBSD. I mean, it's not extremely unique to be able to get files back after a deletion, even windows has features for this since long time. ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

Thanks for your answer. Not true. There are utilities available, and I've seen more than one HOWTO on this subject. Use google. Is anyone aware of an approach to get some kind of soft deletion functionality on freeBSD. I mean, it's not extremely unique to be able to get files back after a deletion, even windows has features for this since long time. CVS, or other version control system. Backup. Intelligent file management. It's rather interesting to note that the Windows world focuses on recovering from mistakes _after_ they happen, whereas the Unix world focuses on working in such a way that mistake recovery will be trivial. Windows - Oops, I screwed up, let me publish the crazy things I had to do to recover from my mistake. Unix - I'm going to do this important stuff. Before I start, I'm going to assume that the fact that I'm human means there's a good chance that I'll make mistakes and corrupt or lose things, so I'll take steps from the get-go to make it easy to backtrack when that happens.

I mean, it's not extremely unique to be able to get files back after a deletion, even windows has features for this since long time. the easiest thing to do would be to prepare for the 'next time'. 1) create a 'garbage' directory wherever you believe it would make the most sense. 2) create an alias within your .cshrc (or bash, or zsh, etc) which, when 'rm' is invoked, uses 'mv' to move the file to your 'garbage' dir. to my knowledge, this is pretty much the same approach used by windows, gnome, and kde. this link should get you started: http://www.cee.odu.edu/uclhd/uclhd_unix_undelete.php hope this helps. cheers, epi __ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED] ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

They should be able to recover some files. -volker ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

| In any event, I can tell you the first thing to do is dd the partition | into a file so that you can make backups before you start attempting | to undelete. i.e. dd if=/dev/ad??? of=/some/part/diskimage, then | cp diskimage workingimage. | | Then you can 3 things: | 1) Start using the computer again if you like | 2) Work on workingimage in an attempt to restore the lost file | 3) Feel confident that if you screw up something on workingimage, |you can just copy diskimage again and give it another go. I'm just running TCT after a suggestion from another writer on this eminent list. For the record this url may help other people that searches in the archives for recover deleted file or undelete file: http://www.fish.com/tct/help-recovering-file I don't have any result yet though. | Why not a filesystem that takes care of that for me? | | Why not a filesystem that keeps itself defragmented, instead of | requiring you to do it every so often? I am in the strong believe that UFS2 is self-defragmenting, atleast I don't have any problems with fragmentation on my freeBSD iron, as opposite to our windows machines then. Point taken though, but it would be nice to have the ultimate filesystem with both some built in user tolerance AND security AND de-fragmentation logic AND smart allocation AND etc etc. | Why do I always | need to do everything by myself, why can't a computer year 2004 be | more fault tolerant, my car is, and so is my CD and my stove. | | How much did you pay for your computer? I think this goes back to | a common misconception that the general public has (which I blame on | MS and Apple) There is no computer available today that is smarter | than a human, even the stupidest human is smarter than the smartest | computer. If you expect the computer to know better than you what | data is good and what isn't, you're about to be repeatedly | disappointed. Yes, you are right, and especially if I choose to run from command line there is no security net between my stupidity and the computers logic. I guess all user tolerant tools must be but between me and the filesystem, atleast that's what's done on Windows. (There's no trashcan in dos ie). | Besides, computers are not remotely like your CD, stove or car. For | example, the fault tolerant systems in your car never have to wonder | if you're doing something you shouldn't or not. | | Your car never has to determine if you really want to hit the brakes | or not. If cars were fault-tolerant on the level that you are expecting | your computer to be, we'd have few or no accidents. I'm really in a | state of mystery as to what kind of car you have that has fault | tolerance such that it protects you from human error! I'd like one | that doesn't let me pull out in front of other people even if I can't | seem them (VERY helpful in Western PA!) Well, today when I panic brake my car helps me not to lock the wheels, to increase the retardation efficence. There are cars that change the power balance between the left and right rear wheels during heavy movements from side to side, to help the driver from forcing the car off the road. So, yes, the cars today certainly helps a bad driver to some extent.
