I have an external NTFS drive from which I was trying to copy some files to my macbook pro 10.6.6.

I was getting error 36 so with disk utility I clicked on Repair Disk. Now all my data is gone!

What gives and how can I fix it?

By the way I was using Paragon NTFS as well.

Try plugging your drive into different computers (Mac and PC). If you don't see anything, you will probably have to send it to a data recovery service if you don't have a backup.
You can also try software to recover data, like DiskWarrior.

As for why DU erased this when you clicked Repair, I have no idea. Are you sure you didn't click Erase, Reformat, or Repartition?

No, I didn't click on erase, I have the log form disk utility. – Ayrad Feb 12 '11 at 16:23

Highly recommend Get Data's Recover My Files program. You can scan for lost files for free but must pay to save them. However, it's a LOT cheaper than paying for professional recovery service.

Get the hard-drive into an external enclosure. Preferably something with a fast interface, like FW800. Image the drive.

Then get yourself some data rescue software (I like Data Rescue 3 -- but there are many out there), and run your recovery software on the image.

Worst case scenario is you send the hard-drive (that you've manipulated very little since you've been operating from a disk image) to a recovery centre.

I had the same problem, and I resolved it with the chkdsk.exe on Windows. The drive mounted and I was able to recover my files.

Welcome to Ask Different! Could you add some detail to this answer? Where is chkdsk.exe found and how is it used? Since this is a Mac-centric site, maybe you could recommend a way to use chkdsk without access to a Windows computer? Please take a look at the FAQs for more info. Thanks. – Nathan Greenstein Apr 26 '12 at 3:57
