The six floppies only provide a way for a user whose system cannot boot from
a CD-ROM drive to begin setup by booting from the floppy drive. Ultimately,
you would still need to access the CD-ROM drive. There is a means of
starting the recovery console with the floppy disks but that function when
begun from the floppies is quite limited.
You might try using System Restore, it can be invoked from a command prompt.
In other words, you would boot the system, start tapping F8, when the menu
appears, you would select Command Prompt and press enter, then follow the
directions in the Knowledge Base Article for beginning System Restore and
see if it can take you back to a time before this began:

Are you quite sure the issue is Easy CD Creator, what version did you
install? Problems with this software should not prevent booting from the
CD-ROM drive as this is outside the XP environment. This issue and error
you describe can be any number of hardware related issues. Also, booting
from a DOS boot floppy is useless if your system is using NTFS as opposed to
the FAT 32 file system as once booted from that disk you cannot read an NTFS
partition.
Given the things you have tried and failed, you are getting close to either
needing the help of a shop or formatting and starting over and because the
error is indicative of some hardware issue, formatting which in this case
would require deleting the partition, creating a new one and formatting the
drive may not resolve the issue.
