Appendix D. Compatibility with
Other Software
This appendix describes the fine points of using the Disk Administrator
together with the following software:
DOS FDISK
Norton Utilities
Disk Compression Software
Other Boot Managers
Anti-virus Software
Disk Overlay Software
D.1 DOS FDISK
Many operating systems like MS-DOS, PC-DOS, DR-DOS, Windows 95/98/ME,
OS/2 and many UNIX versions have in their packages programs that are
usually called FDISK. They are provided for partitioning the hard disk. Many
of these programs have limitations that cause them either to work incorrectly
or not work at all in the following areas:
• Partitions located beyond cylinder 1024 and extended BIOS installed on
the computer are unsupported by FDISK. In this case FDISK might not
list all the partitions and report errors in partition structure.
• Partitions located beyond the geometry that are given by function 8 of
Int 13h if extended BIOS is not installed on the computer. In this case
FDISK may either refuse to run or report errors in partition structure.
• Primary partitions that are located between two logical ones. In this case
FDISK may report either extra free spaces or overlapped partitions.
If you have installed Disk Administrator, you will not need to use programs
like FDISK.
D.2 Norton Utilities
Some programs from the Norton Utilities package, mainly Norton Disk
Doctor, may report partition structure errors, for example invalid logical
partition parameters or partitions that cannot be accessed. You should ignore
these messages and deny attempts to fix the error since Norton Disk Doctor
may damage the partition structure.
