    I had issues with my wifi last week, it was really slow, but only on my macbook on yosemite. All my other devices worked perfectly.

    So I tried to create a new user on the macbook. On the new user account the wifi worked just fine.

    I logged back in to my old account, renamed it to "Name_Lastnameold" but not the user folder (I didn't know about that, then) and created a new admin account which I named just as the old one was named before, so I assume the new user folder had the same name as the old one.

    When I wanted to open my new account today to move the files over to the new account, one message after the other popped up, asking for passwords. Over all finder folders like downloads there was a red minus sign, I couldn't enter the folders.

    Then I activated the root user, through which I granted access to the folders, just to find out that they were empty. Then I checked the Macintosh HD Space and that only 50GB data is on it. Yesterday it had to be about 180GB-200GB.

    So my question is, is these data gone for good or is there any way to restore it? I ran data recovery 4 and Stellar Phoenix Mac Data Recovery, but it doesn't find anything.

    Thank god, I backed up my iphoto library, to move it to the new account, but still a lot of important things are missing now.

    I would really appreciate it, if somebody could help me.

    Putting out the fire with gasoline...
    You need to take care when renaming user accounts, Apple have a support document on it (below). In creating the new Admin account with the same name as the old one OS X will overwrite your data, as you can see by the dramatic change in available disk space.

    At this point if you don't have a full system/drive backup you have bigger problems than before. Personally I recommend SuperDuper. Others may have better advice for a fix, equally it will not come easily.

    What Queen6 said.

    I'll keep it short, but, I am anal retentive about backups. Even the best tools might mess up (read: miss a backup and or item, get corrupt, device fails), so, I do multiple backups, TimeMachine, SuperDuper!, manual, multiple HDs, flash drives, cloud. So even if I've messed up my system bad, it might take a while, but, I can recover my system back to as-was, or at worst, just maybe missing a couple of days worth of things.

    In the case of pictures, I always make a backup after processing a new batch of important to me pics. Again, multiple copies.
