chkdsk /f erased my entire hard drive

I have a Maxtor oneTouch4 500GB external hard drive which I use for back up purposes.  Yesterday I finally decided to make the complete move from Windows to Linux and I installed Ubuntu on my main hard drive (not the maxtor in question).  I installed Ubuntu and when I tried to access my Maxtor external hard drive where I had all my files Ubuntu told me that the drive couldn't be mounted.  Bad sectors existed in the NTFS partition.  The message said that I should run chkdsk /f on Windows.  So I took my maxtor HD and hook it up via USB to my laptop running Windows.  I tried to access the drive from Windows and it said the drive was corrupted.  I ran chkdsk /f and it went through no problems on the C drive, then when it got to my Maxtor drive it fixed thousands of things.  I then rebooted the computer tried accessing the drive, and I was able to, but all my files have disappeared. Are my files completely lost?  I see that the hard drive is still using 10GB which is about the size of all the files I had in it.

Please let me know.  I don't want to think all my pictures were lost

Your data is most probably not lost, but you'll need to get a good recovery software to get it back. The most important thing you can do right now is: don't touch the drive! I mean, don't copy data to it, run chkdisk, defragment or anything else - the more the drive is used, the more data may be lost.

I'll have a look around for a good recovery tool I once used.

Thank you.  I was able to save some of my pictures and even some files I had deleted in the past that now I needed.  Thank you.
You're most welcome, I'm glad I was able to help!
Just read your question again, all this started when you mounted the disk in Linux? I'm an avid linux user and I've mounted NTFS partitions time and again, I've never experienced such behaviour.
My guess is the disk was allready damaged before it was mounted, perhaps it was unplugged without disconnecting properly? Some disks are more susceptible to that kind of errors than others.
