ReadError: Number of read errors detected by this
operation
If a disk error is found, it is possible to erase only the
data that was lost as a result of the error. I.e., the disk
can be restored to a correct operating condition while
keeping as much possible of the non-error data.
* This procedure does not correct the disk error. All error
locations will be erased. This means that depending on the
location in which the error occurred, a take that was
recorded may no longer be playable, auto mix data may be
lost, or even the entire song itself may be erased. If the
error has occurred in the system or song list, the probabil-
ity of this danger is especially high.

A confirmation message appears on the screen.
9-3. The message “You’ll Lose Data” will appears in
the display. Press [YES].
The Recover operation is executed. If you want to can-
cel the operation, press [NO].
9-4. When the recovery is finished, the results are
shown on the display screen. Songs that have
been partially altered are indicated by “Adj”;
deleted songs are indicated by “Del.” Songs that
have not been changed are not indicated. Please
check the display.

Clusters
These are the smallest unit of memory that the
VS-1680 uses to manage data on a disk drive. The
smallest physical units on a disk drive are called
either sectors or blocks, and depending on the
device, the size that is handled can be selected.
For example, the VS-1680 is designed to use disks
with 512 bytes/sector. When the VS-1680 man-
ages song data, it handles 64 sectors as a single
unit (cluster). This means that 512 (bytes) x 64
(sectors) = 32768 bytes (32 kilobytes) is one clus-
ter.
Cross Link
This is an error in which a cluster is detected as
being included in two or more songs. In such a
case, a completely different song may be heard in
the middle of a song. Such an error condition is
referred to as a cross link.
Loose Areas
An error in which clusters not included in any
song are detected as containing valid data. In this
case, the VS-1680 will not store data in those clus-
ters. A situation which causes this error to occur
is called a loose area.
Directories
The VS-1680 stores data such as audio data or
parameter values on disk in units called files. In
order to manage large numbers of files, the VS-
1680 keeps lists of file names and the locations on
disk in which the data of these files is stored.
These lists are called directories.
The “IllegalDIR” message will appear when this
list is incorrect. For example, this message will
appear if the data of a certain file is supposed to
be recorded in an area of the disk which does not
actually exist, or if the list itself becomes perma-
nently unreadable.
