Responding to Messages About Your Hard Disk
The Mac OS 8.1 Installer checks the destination hard disk for errors before installing the
software. Additionally, if your hard disk was formatted with an Apple disk utility program, the
Installer updates the hard disk drivers with the latest version of the driver software. If your
disk drives are formatted with a disk utility from another company, the drivers are not
updated. You should use the third-party disk utility to update your hard disk before installing
Mac OS 8.1.
Note: Before using a disk utility from a manufacturer other than Apple, see the
documentation that came with the software or contact the software manufacturer to make
sure the program is compatible with your computer and the version of Mac OS installed on
your computer. Apple cannot guarantee the performance of software from manufacturers
other than Apple.
Reinstalling Individual Applications
If you’re having problems with an application or it was damaged or inadvertently erased, try
reinstalling that application. If an application came with its own CD, see the software
documentation or the Read Me document on that CD for instructions on how to reinstall
that software. If not, see the Read Me document on the software install CD for instructions
on how to reinstall that software.
Important If you have preferences or settings for individual applications, make a note of
them so you can easily reset them if necessary, after you install system software. If you are
having problems with your computer, you may not be able to open any files with preferences
or customized settings.
