programs improve access times to the hard drive, which will help
improve system performance while writing to and reading from the
CD-Writer Plus drive.
■ A small number of older hard drives are designed with a built-in
interrupt loop that may cause a buffer underrun. If you are unable to
resolve buffer underruns by any other means, contact your hard drive
manufacturer to find out if this is the case for your hard drive.
Buffer underruns could also be caused by an unsupported parallel port
(standard mode SPP). See “Minimum System Requirements” on page A-
1. Try the following:
■ Write data to the CD at 1x speed if you are given the choice within
the software.
■ Disable any printer status monitor software (page 3-7).
■ Change the parallel port settings to EPP or ECP in CMOS, if your
computer can support the change. See the manual that came with
your computer to find out how.
■ If the previous suggestions don’t work you may want to consider
installing a new EPP or ECP parallel port card.
Unable to read a second session reading from a CD-ROM drive
■ Eject the CD and reinsert it.
■ Refresh the screen. Select the My Computer icon in Windows
Explorer and press F5.
■ CD-RW (ReWritable) discs can only be used in CD-ReWritable drives
or newer MultiRead CD-ROMs.
■ If you are trying to read your CD from Windows 3.x: Multi-session CDs
created with Direct CD cannot be read in DOS or Windows 3.x. If
your multi-session CD was created using some other program, verify
that you are using version 2.23 of the MSCDEX.EXE file. First, restart
your computer and when you see “Starting MS-DOS...” appear on
your monitor, press F8. Each line in your CONFIG.SYS and
AUTOEXEC.BAT file will load one at a time. Press “Y” until you see a
line containing “MSCDEX.EXE”. Then press “Y” and the version
number of your MSCDEX file will display. The number must be 2.23
or greater. Call Microsoft for an updated file if you need it.
■ See if the CD-Writer Plus drive or other CD-ROM drives can read the
CD. If so, the problem is probably with the CD-ROM drive. Contact
the manufacturer of this drive for updated drivers.
