CD-ROM drive
Optional PD drive
Hard disk drive
If you have problems accessing a CD, check that you have allowed a
few seconds for the disk to spin up to full speed, that the disk is the
correct way up in the drive, printed side upwards, and that it is a
data CD. Remember that with a conventional CD-ROM drive you
cannot write to a CD.
Check the type of media in the drive, CD or PD disk cartridge.
Remember that the PD cartridge needs the disk inside to be
formatted to allow it to be written to. There is also the write protect
tab to check.
Make sure that you are trying to access the drive by the correct icon
for the media in use.
If you encounter problems accessing the hard disk drive, use the
BIOS Setup utility to check that the drive is correctly specified, and
that the drive's controller is enabled. Check also that the disk has
been correctly formatted, and that the permission assigned by the
operating system allow the intended access.
