SYMPTOMS
CAUSES
SOLUTIONS
CD-R or CD-RW software cannot
detect veloCD.
(continued)
Writing error occurs.
Buffer underrun.
Does not record at max speed.
5. Wrong cable with jumper set to
Cable Select.
1. DMA is not enabled on your
computer.
2. Network is being used.
Mouse was moved or Windows
screensaver activated while
writing.
Other applications are running.
Power save mode is active.
3. Shortage of PC memory. If there
is insufficient main memory in
the PC, data may be swapped to
the hard drive, and this can
cause a buffer underrun.
4. VeloCD and other IDE CD-ROM
drive are connected on the
same cable.
5. VeloCD and hard drive are
connected on the same cable.
6. Automatic thermal recalibration
triggered. Some high-speed hard
drives are equipped with an
automatic thermal
recalibration function.
5. Make sure that a CSEL
compatible IDE cable is used if
you want to use the veloCD with
jumper set to Cable Select.
1. In Windows 95/98/ME, click on
Start button, then select Settings/
Control Panel, then double-click
on System icon, then click on
Device Manager tab, then double-
click on CD-ROM icon. Select
veloCD and click on Properties.
Then click on the Settings tab and
enable DMA. Reboot your system.
Make sure DMA is enabled on
your motherboard.
2. If problems occur when writing,
reduce the load on CPU resources.
Some ways to do this are:
•
Log off from the network.
•
Don’t use the mouse.
•
Disable the screensaver or
power save mode.
•
Exit all other applications.
3. Increase the PC’s main
memory capacity.
4. When writing from another
IDE device to the veloCD on the
same bus using on-the-fly
writing, the IDE bus is very busy
and it may cause writing errors.
This depends on your system
speed and configuration. Use the
image writing method for best
results (safe mode) or record at
lower speed.
Put the IDE CD-ROM drive on
the primary bus and veloCD as
the only device on the secondary
bus (Master).
5. Remove the veloCD from the cable
and re-connect it to a secondary
IDE port.
6. Use another hard drive in
this case.
