That program was on my "famous list of recovery tools for futile attempts". :-) I may say that I have the same problem (of unclear origin). Files have been removed, but the assumption that the data could still be somewhere is alive. In such situations, you would usually have two choices: 1. money Get as much money as you can. You'll need it. Several 1000 euro / dollar / local currency will buy you service at a company specialized in recovery. There is no guarantee they will be successful. 2. time You invest time in learning how UFS works. There are many excellent articles (especially the authoritative one by M. K. McKusick). You try out different tools (with different scope). If you are lucky, you get your data back. (I was lucky once, got my data back!) There are _many_ good tools around. Most of them are free, so you don't need to invest massive amounts of money in a repeating "trial & error" process. Allow me to repeat my list (which gets a little bit modified each time I post it to this list): OS tools: fetch -rR <device> recoverdisk Ports collection: ddrescue dd_rescue <- use this to create images to work with magicrescue testdisk <- restores content recoverjpeg foremost photorec ffs2recov scan_ffs tsk <- The Sleuth Kit fls dls ils autopsy There are some commercial tools worth mentioning: "UFS Explorer" can be run in wine. It probably won't restore your data, but it can be used to determine if there is something to restore. Also consider "R-Studio" and "R-Studio Emergency" (live CD). Those offer free versions that can be used for testing. Finally, I'd like to mention The Sleuth Kit. It's one of the most powerful toolsets, also used in forensics and investigation. As I said, I ran into a similar problem (files deleted). Maybe you can find this discussion thread in the archives and gain some more inspiration from it. A massive data loss (meanwhile cured!) brought me to this list, so I continue to spread my experience about recovery when needed. :-) Good luck! -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
