Roland 24 bit Digital Studio Workstation VS-890 - Manual (Page 72)

Making a Multi-Track Recording
Checking Disk Reliability (Surface Scan)
When initializing a hard disk or other disk, you can confirm that the read
and write functions in all of the disk partitions are operating correctly. This
is referred to as
Surface Scan.
When Surface Scan is performed, it will require somewhat more time to
initialize the drive, but the reliability of the hard disk will be enhanced. We
recommend that you also perform Surface Scan when you initialize a drive.
1
Set Surface Scan to "On," and as described in "Initializing the
Disk (Drive initialize) (p. 69)", carry out the Drive Initialize
procedure.
^ After initialization of the disk is completed. Surface Scan
begins automatically.
3
When Surface Scan is completed, one of the following
messages appears in the display.
“File System Err”
A read or write failure has occurred in a location which stores basic data
used by the VS-890 for recording and playback. This disk drive cannot be
used by the VS-890.
“____ Defect”
The underlined portion will indicate the number of unusable memory
locations in this drive. The larger this number is, the lower the reliability of
this drive.
“™ Complete —”
This drive has no mrusable memory.
Press [YES (ENTER)]. VS-890 will restart.

Canceiinq Surface Scan
You may cancel Surface Scan by performing the following procedure.
1.
Press
[NO (CANCEL)].
"Cancel?" appears in the display.
2.
Press
[YES (ENTER)].
Surface Scan is new canceled. However, the
memory found to be unusable up to that point is not registered.
3.
The VS-890 restarts automaticallv.
Performing this procedure
deletes all contents saved
on the disk: Conduct this
check when initializing
newly purchased disks or
disks which previously
have been used with a
persona! computer or other
device. Be sure to make a
backup copy of any disk
you arepresently using on
the VS-890 before carrying
out the procedure on it.
If there are any places on
the disk where the reading
or writing of data catmot be
performed, the VS-890
registers this as unusable
memory. Recording and
playback then become
unavailable at the location.
The Surface Scan procedure
takes a certain amount of
time. Be aware that Surface
Scan requires some time.
This is not a malfunction.
For example, the time
required to conduct Surface
Scan on one Zip disk
(100MB) is approximately
10 minutes. The time it will
take to conduct Surface
Scan on your disk drive
should be based on the size
(capacity) of the disk. The
progress of the Surface
Scan procedure is shown in
the display.
