Problem
solving
Computer
problems
can
be
caused
by
hardware,
software,
or
user
error.
Using
the
information
in
this
section,
you
might
be
able
to
solve
problems
yourself
or
gather
helpful
information
that
you
can
pass
on
to
a
service
technician.
You
might
also
need
to
refer
to
your
computer,
operating-system,
or
sound-adapter
documentation.
Review
the
following
list
for
any
problem
description
that
might
fit
your
situation.
Transporting
data
with
DVD-RAM
Media
DVD-RAM
Media
can
be
read
on
any
ThinkCentre
DVD-ROM
drive
which
has
RAM-read
compatibility,
but
certain
requirements
must
be
satisfied.
Your
system
either
must
have
a
2.0
compliant
UDF
reader
or
you
must
finalize
the
media
before
it
can
be
read.
If
you
do
not
have
a
2.0
compliant
UDF
reader:
After
data
is
written
to
the
DVD-RAM
media,
it
must
be
finalized
before
it
can
be
read
in
an
ThinkCentre
DVD-ROM
with
RAM-read
drive.
Finalizing
the
media
does
not
prevent
the
user
to
write
more
data.
The
DVD-RAM
media
may
be
finalized
more
than
once.
It
is
impossible
for
the
ThinkCentre
DVD-ROM
with
RAM-read
drive
to
read
the
media
which
has
not
been
finalized.
If
you
have
a
2.0
compliant
reader:
Unfinalized
DVD-RAM
media
can
be
read.
Obtaining
a
2.0
compliant
UDF
reader:
Free
third
party
UDF
reader
software,
such
as
VOB
InstantRead,
can
be
downloaded
from
http://www.vob.de/us/Downloads.htm
Third

software
is
not
supported
