Company Background

Our founder, Greg Brewer is well known in the mass storage industry as one of the pioneers in hard drive firmware, software utilities, device drivers and file systems. Through decades of consulting, Greg has gained unparalleled experience in magnetic media (rigid and flexible, fixed and removable) and optical media (read only and read write) low level format structures, command and control commands (standard and proprietary), and every means of transport (SCSI, ATA, ATAPI, SATA, USB, 1394, TCP/IP and Fiber Channel) to the host computer.

Since 1985 Greg has worked directly with most mass storage companies in a consulting capacity to bring technical expertise to varied product development teams to achieve timely releases of ground breaking products time and time again. A few companies that benefited from Greg’s experience over the years include Adaptec, Apple, Castlewood, Conner, iomega, Motorola, Oxford, Quantum, Ricoh, Seagate, Syquest, Toshiba, plus countless OEM drive resellers.

Highlighted achievements include developing first plug-and-play mass storage driver utility (sold to end users internationally as Drive7, later to be acquired by Apple as the basis for Mac OS mass storage support, DriveSetup). The first universal CD/DVD play and write drivers to support all media types (also sold to Apple as the basis for CD/R support in Mac OS and CD Writing in iTunes).

The first comprehensive diagnostic utilities for mass storage devices, the first universal driver based drive cache performance suite, the first universal drive partitioning application, the first driver based encryption suite for mass storage devices, and the first universal driver that uses TCP/IP to share mass storage devices with other users in the workgroup (DriveShare).

These projects (and countless others) provided Greg and Prosoft with well-rounded experience in single-logical-unit and all forms of RAID (both hardware and software) in direct and net-attached configurations. Few companies can match the breadth of knowledge that has been passed through the engineering ranks of Prosoft Engineering, Inc.

In parallel with pioneering work in the mass storage driver, utilities, and firmware arenas, Greg amassed tremendous experience in file systems through pioneering companies such as Apple (MFS, HFS, HFS+, DOS FAT, and NTFS), Sitka (Tops), and Novell (Netware). Highlighted achievements in this area include one of the first cross platform external file system software to successfully allow Macs and PCs to share media (PC Exchange) and one of the most successful cross platform network operating systems to date (Netware for Mac OS).
