Quota Entry Weirdness !!!! Help !

I just cannot figure this one out. Users have been Migrated from one file

server to another, and I get these wierd quota entries on the new server

The amount used for one of the users is 8.5GB but the limit is set to 2GB.

I checked all files owned by this user on the new server - and the only data

on this server with him as owner amounts to only 1.3GB. So where does the

other 7 odd GB come from ? I cannot find any other files for him that amounts

to this size.

Can anyone please shed some light ?

Thanks
