7. Drive check will begin.
8. When drive check ends, the following display will
appear. Rotate the TIME/VALUE dial.
To stop during the procedure
To stop the drive check during the procedure, press [CAN-
CEL(NO)].
If the display indicates “No Err”
9-1.The entire disk could be read correctly. Press [YES].
You will return to Play condition.
If the display indicates “___ Err”
The underlines portion will display the number of times
that a read error occurred. Rotate the TIME/VALUE dial.
The display will indicate ÒErrÓ for locations where an error
was found. Locations for which ÒOKÓ was displayed have
no problems.

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.
< Clusters >
These are the smallest unit of memory that the VS-880
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-880 is designed to use disks with 512 bytes/sector.
When the VS-880 manages song data, it handles 64 sectors
as a single unit (1 cluster). This means that 512 (bytes) x 64
(sectors) = 32768 bytes (32 kilobytes) is one cluster.
< 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 complete-
ly 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-880
will not store data in those clusters. A situation which
causes this error to occur is called a
Loose Area.
< Directories >
The VS-880 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-880 keeps lists of filenames
and the locations on disk in which the data of these files is
stored. These lists are called
directories.
The
Illegal Directory 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 permanently unreadable.
