Atari 810 Disk Drive 233
If a diskette contains bad sectors, DOS will not format it. After
the initial discovery that the diskette contains bad sectors, DOS
will attempt to format the diskette two more times. Upon the
third unsuccessful attempt, error 173 (Bad Sectors at Format
Time)
will be displayed.
Be certain that you do not format a diskette that contains data
you wish
to retain. Formatting a diskette destroys any existing
data
on that diskette.
J. Duplicate Disk
The Duplicate Disk operation allows an entire diskette to be
copied. This
operation can be used with Atari systems with either
one or two disk drives.
When Duplicate Disk is specified, the following prompt will
appear.
DUP
DISK--SOURCE, DEST DRIVES?
The user should respond with the drive number containing the
diskette
to be copied , and the drive number which will contain
the diskette in which the copy is to be made.
If your Atari system has only one drive , you should respond to
this prompt with an entry of 1,1.
The
following prompt will then be displayed.
INSERT SOURCE DISK, TYPE RETURN
The user
should then insert the diskette to be copied in the sole
disk drive and press Return. A portion of the data stored on the
diskette
will then be read into the Atari's memory. The following
prompt will then be displayed.
INSERT DESTINATION DISK, TYPE RETURN
The user
should then replace the diskette being copied with a
blank formatted diskette and press Return.
