News Release

SAN DIEGO and PHOENIX--(BUSINESS WIRE)--Oct. 23, 2000--Overland Data, Inc. (NASDAQ:OVRL), a technology leader in tape backup products, and Enhanced Software Technologies, Inc. (EST) announced today that Overland's AIT(a) LibraryPro(TM) automated backup tape library is certified to run under Linux.

EST sponsors and administers the Linux Tape Device Certification Program.

"EST's Linux Tape Device Certification Program gives end users the quality assurance that the Overland product family demonstrated complete compatibility with the Linux Operating System," said Steve Richardson, vice president of marketing at Overland. "Our award-winning automated storage solutions offer the broadest possible range of interoperability and third-party support, extending our commitment to ease of use and installations for the largest variety of users."

"EST is providing a valuable service to the Linux community by creating the tape certification program," said Jon Hall, executive director of Linux International. "Their position as Linux backup experts gives them great insight in answering the question: what tape drives work with Linux? This is the program's benefit to Linux users."

The AIT LibraryPro, the first scalable AIT library, can be scaled up to nine modules for a maximum configuration of 8.55 terabytes native capacity (22.2 TB with compression) and throughput of 388 gigabytes per hour (1.0 TB/hr. with compression) using Sony AIT-2 drives. LibraryPro allows customers to scale the capacity and performance in modular increments for a customized solution to precisely match their specific storage needs, and combines the company's ultra-reliable Mainframe Class Robotics technology with the inherent advantages of Sony's AIT technology. Along with the unmatched scalability of the LibraryPro, Overland adds simplified media management with a tape cartridge magazine design to facilitate bulk cartridge installation and storage, as well as a convenient mail slot for individual tape insertion into the library.

About the Linux Tape Device Certification Program

Tape drive certification through the program entails the use of a static, open set of test procedures specialized for Linux that are application-independent. This process ensures that the testing is unbiased and that all devices are appraised on a level playing field.

Tape drive manufacturers are awarded the use of the "Linux Compatible" logo for each product certified. The logo can be used on manufacturers' marketing materials and serves as an indication that they support Linux.

"The acceptance of Linux is fostering a growing number of tape drive options to choose from," said Ted Cook, president of EST. "The certification program is designed to provide information to enhance tape drive purchase decisions and highlight those drive manufacturers committed to the Linux movement."

As part of the certification program, EST maintains a site at www.linuxtapecert.org, where the test results of the LibraryPro are posted. The test scripts are also available for download by end users to allow testing of their existing tape drives for Linux compatibility.
