|  |     I recently moved my files from an RZ23 to a RZ24. Prior to moving the
    files all the partitions on the RZ23 had been defragmented using 
    QuarterBack Tools. After the move QBT reported 1350 files fragmented
    out of 1790 . I think it did say there were two free sections of disk.
    I went out and defragmented the partitions on the RZ24. Now the RZ24
    was freshly formatted in AmigaDos, and the RZ23 was pretty clean. I
    don't know how the fragmentation is happening but I was dissappointed
    to say the least. I haven't bothered to restore a partition with
    QuarterBack yet, so I don't know how well the defragmentation holds up
    with backups. I would hope it keeps the files defragmented. Aside from
    defragmenting QBT will also make an effort to place your .info files
    on the disk for better workbench performance. I use some 700k+ files
    with imagine so I try to keep them defragmented as much as possible.
    	Aside from using QBT I never save data to the partitions that hold
    my OS, and Application software. It often takes a second longer to save
    data(specify a different partition) but then I figure it helps to keep
    the partition clean.

    Bill,
    
    I ran into some disappointments in the area of backup.  I "assumed"
    that the sequence of doing a Quarterback backup, deleting all files
    in the partition, and doing a Quarterback restore, would give me
    a dfragmented partition.  Wrong!  And the folks a Central Coast
    said this should work.
    
    I then did another variation of the experiment.  I first defragmented
    using QBTools (so I know my starting point).  Then I did the Backup,
    Delete, Restore operation and sure enough, QB tools says I'm fragmented
    all over the place. 
    
    I was disapointed and don't know what to conclude.  Central Coast
    initally said it would work.  Is it really fragmented or is there
    something funny in QBTools that makes it "think" it's fragmented.
    I've called a couple of times, but since Central Coast became part
    of New Horizons I've not been able to contact anyone that knows enough
    about this software to answer questions.
    
    Assuming that both Quarterback and QBTools are working correctly,
    I can only guess that the AmigaDOS I/O system does nothing in the
    way of disk organization to minimize fragmentation (even on an
    empty media you get it).
    
    I try to keep my partitions no more than 1/2 to 3/4 full and I can
    honestly say I don't notice any difference in performance whether
    they're defragmented or not.  I also believe that there are probably
    zillions of ways files can "technically" be fragmented and not be
    costing you performance, there are to many other considerations in 
    the system.  I wouldn't exactly call my A2000 a "balanced system"
    when it comes to performance.
