    Sorry I'm posting this again, I think this thread needs to be in OSX rather than in MBP:

    WOOWWW!!!!! I really don't know what to do now! My external HD disappeared after I installed lion recovery disk assistant to it with all my information on it! I just can't believe this recovery erased everything I had on my HD!!!! I know I'm freaking out, but this was my backup external HD close to 1TB personal info on it, I stored all my files there to keep my MBP hd clean!!!!! HOW CAN I UNDO IT? I hope there is a way!!!! :confused::confused::confused::confused:

    I'm pretty sure that's what it's meant and expected to do.

    Whoa. You took a disk that wasn't junk and ran the recovery partition utility on the thing? Big oops. I would recommend picking up a $15 8GB usb stick and running the recovery partition creator on that thing, not a 1TB disk full of stuff you care about. At this point, you might be able to get some of your stuff back using disk utility on the USB drive. Whatever you do, slow down and take your time. You might get support from Apple on this one since you just bought Lion you get 90 days of phone support. See if Apple support tells you there is anything you can do (in terminal or disk utility) to get your stuff back. Then use a disposable usb stick and not your important data disk next time.

    Thanks for quick answer. If I only knew it before!!!!! I was thinking that it will put a folder in my HD that will be bootable just in case. But it completely changed my external and all my information on it is hidden now. Disc utility won't even recognize it.....

    Quote from the Apple Support KB article ( http://support.apple.com/kb/HT4848 ):

    How to use Lion Recovery Disk Assistant

    The Lion Recovery Disk Assistant will erase all data on the external drive when creating the Recovery HD. You should either backup your data before running the Lion Recovery Disk Assistant, or create a new partition on the external drive.



    Take this as a lesson going forward - *always* make sure you have a backup of your data.

    You might try a data recovery program but I am willing to bet that most of it is gone. Defo lesson learned....

    Don't tell me you didn't read the red text next to the yellow exclamation mark?

    You can probably use disk recovery software to get back most of the lost data, since it didn't get overwritten. Try TechTool Pro or something like that!

    Not to sound like a jerk, but it's always best two have two external backups. I have one external drive that I use to backup regularly, and the other I use to backup like once every month. I have so many photos(that can't be replaced), documents, music, videos, etc: that I don't want to take any chances. Believe me, I've learned the hard way before too. One time it was when I was messing with a Linux install and the other was when the external drive just failed on me.

    I understand your frustration, but why did you post this in two forums?

    Crap... I wonder why the assistant doesn't check whether you're installing on a USB thumb drive or on a proper hard drive. It should have a security check, not allowing you to easily install it on anything larger than an 8GB partition...

    But ALWAYS read everything, especially red letters!

    If that was the only copy of your data then it was not a backup. To have a backup you would have to have at least two copies of your data. Hopefully you learned a very important lesson on what a backup is and how to properly maintain backups.

    The recovery assistant only wrote about 600MB to your disk. It definitely may have overwritten some of your data, but the rest should technically still be present on disk, although not readily retrievable anymore. You would need some kind of data recovery tool to hopefully get at least some of it back. You may even want to contact professionals about this, if the data was truly important.

    Yeah,,,,now I have 1TB of nothing with lion installer!!!!
    I don;t think it erased everything on it, it would take long time to erase, but it installed lion recovery in 10 seconds or so....is there a way I can uninstall or erase it so I can see my HD again?

    I would try a partition recovery software.

    Quoted for emphasis. A "backup" is another copy of your data. If you put everything on an external drive and erase the originals, then you no longer have a backup.

    The point of a backup is if *either* media gets damaged, the originals or the backups, either one can be restored fairly quickly. If you're in a position where losing a drive means losing data, then you don't have a good backup strategy.

    The best strategy out there is something called 3-2-1 backups. Three copies of everything, two different forms of media, one of those backups offsite. I know this doesn't exactly help the situation right now, but use this lesson going forward to make sure you don't get bit by this again. We've all lost data, and we've all learned the hard way.

    You're data has been erased. That's what the Lion Recovery Assistant Tool warned you what would happen (in bold red letters with an exclamation symbol as well). There's no way to "uninstall" the recovery partition and revert back to your old drive. It's already reformatted it. It's done.

    The best bet you have is to first *disconnect* that drive and don't write anything onto it. Then, find some sort of file recovery tool out there that works with Mac formatted disks. You *might* be able to recover your files from the drive, you might not.

    Again, I want to stress this so that you wise up and never let yourself be in this position ever again - you did not have a backup. If your external drive is your only copy, then it's not a backup anymore.

    Well, second partition of another 1TB on same external HD is Time Machine. So I do have second backup to it...first 1TB was my main partition where I copy all files manually and then erase from computer to free up HD.

    Thank you, will try right now!

    You have your "backup" on the same drive as primary data????!!!!...unbelievable! Whether you do something or the drive just fails, how did you THINK you would save information? Unplug it. Get a data recovery program. If that fails and the information is critical, there are oodles of data recovery companies that will charge you a bundle to get back recoverable information.

    An expensive lesson learned: have a rational, workable backup plan BEFORE it's needed.
