- Atari 520ST Disk Utilities
- by Ravi Kulkarni
-
- The Atari ST comes with a basic set of utilities integrated into the
- desktop to copy files and disks, format disks, etc. However, if you have
- the basic one-drive system, you will quickly find that it becomes quite
- inconvenient to do simple things like copy files and impossible to
- correct mistakes like accidently deleting a file. To make some of these
- tasks easier and also provide additional capability to fix and learn
- about internal system functions, many companies have come out with a set
- of disk utilities. We review here the products by Michtron, Holmes &
- Duckworth, and Haba Systems.
-
- All three programs provide the basic utilities to examine and modify
- disk sectors and to recover deleted files. All three also use the GEM
- interface with menus to provide a user-friendly front end. The programs
- differ however in performance and in the number of features.
-
- The MichTron disk utilities are nice in that they are integrated in
- one program. There is also an optional separate program to enable fast
- copying. Michtron seems to have adopted the policy of unbundling their
- software including their ramdisk and printer spooler. Taken together
- they are an attractive package. However split apart they are less so.
- The disk utilities are nicely done. The disk sectors are displayed in
- both HEX and ASCII and the update is very quick in moving to different
- sectors. To modify a particular location one simply points with the
- mouse and types in the new value. The disk can be accessed by
- track/sector as well as by file. One can search through the file for a
- specific string. The file recovery is nice in that it displays the
- deleted files and gives you a choice of which to try and recover. There
- are a few bugs, namely if there is an error reading the disk it displays
- the old track/sector information while indicating that it is actually
- displaying the new track/sector. One missing feature is the inability to
- display and edit memory. This feature is helpful if you want to poke
- around and look at the ST's memory. The copy sector feature is available
- and is useful to create bootable double-sided disks.
-
- The H&D utilities are separate programs so if you want to do several
- things, you have to exit and run a different program. One useful utility
- that it has is a directory print program so you can avoid screen dumps.
- The H&D programs have the basic features of the MichTron program plus a
- memory editor. However the screen update of different sectors is much
- slower than either the MichTron or Haba programs. Also one has to enter
- by hand the sector and track no. desired. The editing of the sectors is
- also inconvenient in that one can only edit in ASCII or HEX at one time.
- A plus point is that the menu allows a HEX/ASCII dump of the current
- sector which MichTron does not have.
-
- The Haba disk utilities are nicely integrated like those of
- MichTron, but it is copy protected which is ridiculous for something as
- commonly used as disk utilities. Also there are a few fatal bugs that
- can cause the system to hang. The documentation is online but is so
- painfully slow to peruse that it quickly becomes frustrating. The basic
- features are similar to the MichTron utilities with the additional
- feature of memory editing. The screen update of different sectors is
- fast, but one can only address the disk by the absolute sector no. and
- not by track/sector. The fatal bug is when you are merely viewing the
- disk and you perform some function that makes the program try to write
- out the sector. A dialog box appears with a cancel box, but the mouse
- arrow disappears so one can only continue to retry. Some plus features
- are the ability to save sectors to a file to be printed later or to merge
- with another file or disk. Also one can set the default drive wheras
- with MichTron or H&D one is stuck with the drive that you started out
- on.
- All three programs provide useful features with the MichTron and
- Haba programs having a better user interface. However when one compares
- these programs with those available for other computers such as the MAC
- or the IBM PC, the quality of the programs is a little disappointing.
- The IBM for example has a print formatter, memory and disk testing, ASCII
- and HEX dump, directory check for checking the integrity of the file
- system and so on. The user friendliness of the ST programs is without
- question superior. One can only hope that the second generation of
- utility programs provides the quality of features as well.
