My freebsd partition changed by Windows chkdsk

[Leslie Jensen]

I've replaced my dual boot hard drive with an SSD.

My hard drive had one 100 GB windows partition and one 300 Gb Freebsd 
slice with five partitions (/, /usr, /var, /tmp and /home).

In order to move my Win7 partition a Norton Ghost program was supplied 
with the new disk.

When trying to clone that partition the process couldn't finish because 
it needed a chkdsk command to be executed before cloning.

I ran a chkdsk c: with the choice of correcting errors.

Somewhere in that process the chkdsk program touched my freebsd 
partition in a way so that it now is recognized as NTFS.

That I trusted the chkdsk program to do what I told it to do was in 
retrospect a bit naive ;-) I do have a backup although it's not as 
recent as I would have liked.

Can you think of any way to perhaps recover the data from the freebsd 
partition?

Thanks
