is available on the HP StorageWorks CD-ROM or on the HP Support web site. However, certain

Installation process

The CD-ROM contains a driver install package for the supported Microsoft Windows operating systems,
see

. If you prefer to use Windows Device Manager to install the

tape drivers manually, you will find them in the drivers directory on the CD-ROM.

IMPORTANT:

We strongly recommend that you use the installer package on the HP StorageWorks CD-ROM to
install the drivers BEFORE you connect the tape drive.

Updates to the drivers may be provided from time to time on the HP support web site (

http://

www.hp.com/support

). We recommend that these are installed after using the installer on the CD-ROM.

Recommended install process, before connecting the tape drive

Insert the HP StorageWorks Tape CD-ROM.
