Installing on Windows
Two drivers are required in order to use HP StorageWorks DAT USB tape drives.
HPDAT: This is the HP Tape driver that works with all HP DAT products. It is regularly updated and
is available on the HP StorageWorks CD-ROM or on the HP Support web site. However, certain
software applications require you to use their own driver. Always check the software vendor's
documentation or web site before installing this driver.
USBSTOR: DAT 320 tape drives only. This Microsoft usbstor driver is loaded automatically by the
Operating System. The user does not need to install it.
HPUSBMSC.SYS: all other DAT models. The HP USB Mass Storage Class Driver is specifically for
DAT Tape Drives prior to DAT320 such as DAT72 and DAT160 Drives. It must be installed by the
user. The HP USB Mass Storage driver is installed by running the driver installer from the CD
supplied with the HP StorageWorks tape drive, as described below, and is also available on the
Support website. To check the driver being used on the system, use Device Manager as described
in Ensure that the HPUSBMSC.SYS driver is being used (Windows) on page 63.
Installation process
The CD-ROM contains a driver install package for the supported Microsoft Windows operating systems,
see http://www.hp.com/go/connect. 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
1. Insert the HP StorageWorks Tape CD-ROM.
2. Select the install drivers link.
3. Run the automated installer and follow the process to load the required drivers onto the system.
