DISK DRIVE HEAD CLEANING
After a prolonged period of use, disk save and load errors may become frequent due mainly
to dirty disk drive heads, indicating that the disk drive head may need cleaning. This can be
done using a good-quality fluid-type head cleaning kit for 3.5 inch (double-sided) disk drives.
Do not use a cleaning kit intended for single-sided disk drives.
1. Moisten the cleaning disk with cleaning fluid.
2. Insert the cleaning disk into the disk drive.
3. Execute a load function. An error message will appear. This is normal.
4. After approximately 10 seconds, eject the disk.
NB. Do not use the disk drive for about 5 minutes.
PRECAUTIONS TO OBSERVE WHEN USING WK2 DISKS WITH A COMPUTER
As occurs with the MS-DOS operating system, WK2 assigns file names not longer than 8
characters, plus an identifying extension of three characters.
In the Macintosh, OS/2 and Windows 95 systems, a file name can be longer. When a name
is modified on these types of computers, the following rules should be observed:
• do not change the file extension because it identifies the file type and therefore, the
relative structure.
• do not write names longer that 8 characters.
Furthermore, owing to some limitations of the MS-DOS and Atari systems (which other
systems do not have), it is essential to bear in mind the following advice:
• do not insert spaces within a file name (e.g.: «MY FILE»). MS-DOS is not able to
recognise file names containing spaces. To separate a name into two parts while re-
taining the MS-DOS compatibility, you must proceed as follows:
separate two parts by the “underscore” symbol (e.g.: «MY_FILE»).
• do not assign two files the same name, one with uppercase letters and the other with
lowercase (e.g. «MYFILE» and «myfile»). MS-DOS and Atari make no distinctions
between uppercase and lowercase characters.
