Yes, I know Linux and of course I know dd with it's options, moreover that was the first thing I tried (after I went out of "panic mode" :) > Does R-Studio copy the entire disk including GPT specific parts, or does > it copy partitions of disks? I've been working with R-Studio for many years and absolutely sure that it does complete copy of the drive as it is, no matter what the file system is. > When you say a disk "failed", > what does that mean? First, ZFS showed the drive unavailable. Second, the disk has a bunch of bad sectors and took forever to copy first 500MB both with dd (conv=noerror,sync) and R-studio > I feel bad for you losing precious family history. Thanks for understanding, i appreciate it! As I already said earlier, I was in the middle of my backup server build, when it all happened :( > Anyway, have you asked for help on any OpenZFS list yet? No, I have not, but if you could direct me somwhere, it would be much appreciated! The Best Regards, Evgeny.
