Restoring Backup File & warning message

nicole

Recently had to reformat the hard drive and start from scracth (system files
were corrupted). We have our personal files backed up on an external hard
drive. When I use the Backup Utility to restore the files to their original
location, I get a warning:

"warning: the target file system does not support some of the features of
the original file system. Some data may not be restored as a result."

After pressing OK, the computer processes the restore, but no files actually
get restored. I can see the files while in the Backup Utility on the ext.
hard drive but I don't want to have to manually restore things

Our desktop is now operating with SP3; i can't remember what SP was on the
computer before we had to reformat. Please help! Thanks in advance!
