SYMPTOMS
CAUSES
SOLUTIONS
VeloCD drive has read errors, may
not respond to a DIR command or
cannot run a program.
Cannot use other CD-ROM drives to
initialize or discs written by veloCD
.
1. Defective CD-ROM, CD-R, or
CD-RW disc.
2. Fingerprints, contaminants, or
scratches on the disc’s surface
may prevent the drive from
reading or writing data.
3. Bad connection between
the veloCD drive and
the motherboard.
4. CD-Audio disc in the drive.
Audio CDs do not have computer
data, so typing computer
commands in DOS while an
audio disc is in your drive gives
an error message.
5. Disc is inserted upside down.
6. Blank CD-R or CD-RW disc is
inside the drive.
1. Trying to read a CD-RW disc in
a CD-ROM drive that does not
support it.
1. Clean the disc as detailed on
page 19.
Try a different disc.
2. Try a different disc.
3. Inspect the IDE cable and drive for
recessed, broken, or bent pins.
Inspect the IDE ribbon cable
for any signs of distress, such
as kinking.
4. Use a data CD in the veloCD drive.
5. Eject the disc and load it with the
label or text side up.
6. Remove the disc from the drive
and test it by using another disc.
1. Use the veloCD to read CD-RW
discs or use a different CD-ROM
drive. Only CD-ROM drives
manufactured after 1997 can
read CD-RW discs.
Cannot use other CD-ROM drives to
initialize or discs written by veloCD
.
(continued)
Excessive noise.
Excessive vibration.
Slow read performance.
2. UDF reader is not installed on
the system to read CD-RW or
packet written discs from a
CD-ROM drive.
3. Session was left open on a CD-R
disc and does not have a Table
of Contents.
1. CD is poorly balanced. Poorly
manufactured discs or discs
with poorly distributed ink on
labeling cause significant
vibration at high speeds because
they are out of balance. Read
errors may also occur.
If the disc label (especially
adhesive labels) adds more
weight to one area of the disc
than another it can also cause
the disc to be out of balance.
2. Refer to your packet writing
software manual for how to obtain
a UDF reader and install it on the
computer where you need to
access these discs.
3. Place this disc back into veloCD
and use the same software
originally used to write to it.
Then close the session/disc.
1. Carefully remove any adhesive label.
Clean the disc as detailed on
page 19.
In Windows 95, 98 and NT 4.0
use CD Blender to lower the
drive speed.
If there is no foreign substance
on the disc, contact the disc
manufacturer for a replacement.
