Ran fsck, now all files are in lost+found

[Bryant Eadon]

So, I moved a RAID5 device between a FreeBSD 6.0 machine to fresh FreeBSD 7.0 
machine.  When I attempted to mount the device the OS complained that the disk 
had not bee unmounted properly -- figuring it was probably correct, I diligently 
dropped to single user mode and ran fsck on the disk.

I ran 'fsck -t ufs -y'.  all seemed fine and dandy until I tried to remount the 
volume after bringing it back to multi-user mode.  The disk space was occupied, 
but it all resided in lost+found with names like :  #0000001   ,  #0000002 
etc... !!  Each file was multiple gigabytes worth of data without file 
structures (as far as I could tell)

Is there an way to recover from this problem ?   I would be losing quite a lot 
of data, any help you could give would be appreciated.

Help,
B
