1.2.2 Disk Formatting
New disks are preformatted from the manufacturer. This process is called
“low-level formatting”. It is only useful after having cleaned a disk that
had numerous defective blocks. Low-level formatting will then re-check
every bit on the disk for validity, which can take up to 40 minutes.
In order to start recording, the D424 only has to add the basic system files.
Building up a DOS system and installing the basic D424 files is called
“high-level formatting”, or simply “formatting”. This process takes only a
few seconds.
After inserting a new, empty disk for the first time, the D424 will auto-
matically ask for formatting. Any prerecorded disk may be re-formatted at
any time. This is a fast and direct way to delete the whole contents of a
disk.
