SOFTWARE REVIEW: TUNE UP! by Eerk Hofmeester
No, we are not discussing a new program for car mechanics here,
nor a musical tool with the latest technology in earvastating ST
sound chip programming (of which the latter would be very welcome
by the way). 'Tune up!' is a so called 'Hard disk optimizer' with
which you can rearrange the files on your hard disk and their
structure resulting in faster performance and, most important,
disk access is sped up. It's a program by Dave Clemans and
released by Michtron Inc. in the UK (Marko software in the
Netherlands).
Before I really start with my comments on the above mentioned
functions, I would like to quote the manual to give an idea of
the makers reasons to make this program and to explain the way
'Tune up!' works:
"Initially the hard disk environment is wonderful. you can get to
your data much faster, and larger amounts of storage can used
more easily.
After a period of time though the hard disk becomes much less
'wonderful'. Seemingly the more you use the system the slower it
gets.
While a part of that 'slowness' is due to the amount of data on
the disk, typically that is not the major reason. Disk systems
can read or write contiguous groups of information much faster
than they can read or write information scattered across the
surface of a disk.
When a hard disk is new all free space on the disk is contiguous
and thus all files written to it will be contiguous. Thus when a
hard disk is 'new', you are seeing its maximum speed. As you
create and delete files while running applications, free space
starts to get fragmented. Eventually files will have to be
written to scattered hunks of free space. To read or write to
those fragmented files, the system will have to move the hard
disks heads back and forth among the hunks of the file. This is
typically the cause of hard disk 'slowness'.
Hard disk optimization
One way to give your disk system back its 'speed' would be to
make a complete backup of the disk, then reformat the hard disk,
and finally restore all the files from the complete backup. This
procedure does give you what you want: all files become
contiguous and free space becomes contiguous. This procedure is
time consuming, especially for large hard disk systems. It is
also difficult for any information about optimal locations for
files vs. free space to be applied.
This is where 'Tune up!' comes into the picture. 'Tune up!'
performs an optimal locations algorithm across the file blocks
and free space on the selected disk that gives the following
results:
A. All files (if at all possible) are stored in contiguous disk
blocks.
B. All free space is in one contiguous region on the disk.
'Tune up!' supports two algorithms for determining how to place
files and free space. If optimizing for read access is selected,
files are placed at the bottom of the disk partition, and free
space is placed at the top. This minimizes head movement when
reading existing files.
Alternatively, 'Tune up!' can optimize for read/write file
operations. In this case free space is moved towards the
beginning of the disk, and files are moved towards the end. This
makes it much cheaper to create and write to new files. If this
optimization method is applied repeatedly, eventually permanent
files will all be at the end of the partition, with temporary
files at the beginning. This makes it much harder for files to
get significantly fragmented."
Before I enter the complete text of the manual here it's better
to commence with the actual reviewing. To start with the most
important remark: reading the function list of 'Tune up!' makes
it look interesting enough for every hard disk owner. But, and
here comes out the so far carefully hidden 'but', a program that
is moving around with up to 10 Megabyte or more of your valuable
files must be absolutely bug free.
Testing the program on my hard disk (Richard Karsmakers, our
beloved editor of our even more beloved ST NEWS, at this moment
producing very cow-like noises next to me, happens to be in no
position of testing hard drives, not owning one of these
wonderful vacuum cleaner-like massive storage devices), I found
this last point (referring to the 'bug free' demands for this
kind of program) not absolutely satisfactory.
Being the cautious user I am, I backed up the partition I wanted
to tune up, before using the 'Tune up!' optimizer. Of course it
can be purely coincidental, but after tuning up (during which I
was warned a few times that 'Tune up!' needed a second try to
finish the job) the complete partition looked normal but acted
completely weird. A few folders couldn't be opened any more (if
you tried, my ST just 'exploded' with multiple bomb errors), a
few files were so totally crashed that I couldn't even erase them
any more and all in all my drive was far from tuned up. A
normally working motor was tu(r)ned into something looking like
the self made moped of my brother, before he put it together that
is.
After restoring the backup (completely erasing the partition
first) all worked normal again, so in this case no real damage
was done. To be honest to Dave Clemans, I have only tested the
program once; my hard drive is filled with hundreds of very small
data files; I can't tell for sure if 'Tune up!' has been the
'guilty party' in ruining my drive partition; the described mess
was not so big as my literary explanation suggests, but fact is
that important parts of the file structure on one of the
partitions of my hard disk were suffering from very 'file
organisation-like' diseases just after using 'Tune up!'.
The idea behind 'Tune up!' is very good and every hard disk user
could benefit from its functions. A thorough checking of the
product is necessary I think but it has the potentials of a very
handy utility.
