install problems from a newby

[LANCE ASHENHURST]

What package:?  The install program tries to read the cdrom and returns screen dumps of "hda media error (bad sector)  Drive Ready Seek Complete Error, Buffer I/O error  error=0x34  status=0x51".  Is this a cdrom package or install package?  At first I didn't even know what was meant by "package".  Tis is to let you know my limited knowledge about debian.  Thank you for your help.
