Discs and disc drives
The contents of the disc will be displayed in a directory display:
Write-protecting a floppy disc
If you write-protect a disc, it means that you cannot change anything on the disc,
delete anything by mistake, or save any new files to the disc. You should write-
protect discs containing any information you don't want to lose (and don't want to
change at present).
To write-protect a disc, move the plastic tab (on the underside of the disc) towards the
edge of the disc with your finger nail:
Remove write-protection by moving the tab back again.
Floppy disc storage sizes
Floppy discs are a bit like audio cassettes–they both store (or record) information. Some
audio cassettes hold more information than others (for instance, a C90 holds more than
a C60) even though they are the same physical size.
This is the same for floppy discs – the discs your computer uses are all 3.5" in
diameter, but are available in different storage sizes. You can use the following sizes
of floppy disc with your computer:
• double density floppy discs, holding 800 kilobytes (800KB) when formatted (
Acorn ADFS 800K (E) format)
• high density floppy discs, holding 1.6 megabytes (1.6MB) when formatted (Acorn
ADFS 1.6M format).
