Setting The Disk Unit's Functions - Sony RMO-S561 Bedienungsanleitung

Setting the Disk Unit's Functions

Use function switches (A – H) on the rear panel
to select the disk unit's functions in accordance
with the host computer and software you are
using. Be sure to turn off the power before setting
the switches.

■ Write Cache Precautions
This disk unit is equipped with a write cache
function. When the write cache is enabled, never
turn off the disk unit power without making sure
that all data has been written to the disk from the
cache memory.
Data will be lost if you turn off the power before
all data in cache memory has been written to the
disk. Before turning off the disk unit power, be
sure to eject the disk, as this writes data from
cache memory to the disk.
Further, even though the drive will periodically
flush data from cache memory periodically to the
disk, data may be lost in the case of a power
failure.

■ Ultra SCSI Precautions
Using the Ultra SCSI function requires that an
Ultra SCSI cable be used to connect the disk unit
and the host system. It is recommended that the
cumulative cable length be minimized, and that
the cable length be kept under 3 m in length
when connecting up to four SCSI peripheral
devices. In all other cases, the total length of the
cable should not exceed 1.5 m. Further, the SCSI
bus termination should be well maintained.
■ Precautions for Handling the 1024
and 512 bytes/sector
Note that this drive uses a sector size of 4096
bytes/sector. If you insert a disk with a sector size
of 1024 or 512 bytes/sector, the drive internally
converts the sector size of software to emulate a
sector size of 4096 bytes/sector.
Further, data already written to the disk may be
lost if the power is accidentally turned off while
data is being written to the disk.
Be careful when operating the power switch.
