We are planning on releasing a new version of Data Backup by summer, that will give users more flexibility and options for their backup plan.


Prosoft has launched three new products in 2012: MediaTools Wipe, Photo Transformer and SoundBunny.

  • MediaTools – Wipe is an easy-to-use professional software tool for disk wiping and permanently erasing data from your hard drive(s).
  • Photo Transformer provides fast, easy and automatic categorization of images by type, date, size, and many other parameters. The categories can be used to easily find all the images you are looking for and then process them in a variety of different ways.
  • SoundBunny allows you to independently control the volume levels of open applications on your Mac.

The Data Rescue Center has grown 200% over the past few months and is looking to expand its team of professional recovery engineers.

Back in June of 2010, Prosoft and The Data Rescue Center finalized the purchase of a building in Livermore, California, near the Lawrence Livermore National Lab. Work immediately began on the design and construction of the new recovery lab facility with a goal to be operational in less than a year. In late January of 2011, both Prosoft Engineering and The Data Rescue Center moved all operations to this new facility. Boasting a Class 2 UL-Listed Vault as well as extensive security features, the new Data Rescue Center facility sets a new standard in the industry for customer data security, unmatched by any competitors. The all-new ISO 5 / Class 100 Cleanroom exceeds all manufacturers specifications for cleanroom recovery environments. This new facility provides our recovery engineers with the top technology and innovation to recover computer data while offering best-in-class security features.


July 2009, Prosoft launched a new division called The Data Rescue Center.

The Data Rescue Center was founded with the goal of offering world class hard drive recovery solutions at an affordable price. Based in Pleasanton, California, The Data Rescue Center is dedicated to bringing you the very best hard drive and data recovery options. Specializing in RAID Recovery, SSD Recovery and Flash Media Recoveries. All at an affordable and fair price for individual and businesses.

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.

Drive7_psoftSince 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, still sold by Prosoft today).


Company History

Prosoft Engineering, Inc. was established in 1985 and started out as an engineering services company doing contract work with many of Apple’s key developers including Disney, Epson, HP, Intuit, Iomega, Microsoft, Sony, TDK and VST. Prosoft has licensed multiple technologies to Apple including disk utilities, plug-and-play drivers, CD burning software, Drive Setup®, password protection and disk image mounting. You might even remember some older products from Prosoft: Drive7, Chaos Master and CD Master are just a few.

2002 - Today

Today Prosoft Engineering, Inc. creates award-winning software designed to be easily used by both novice and expert users. Prosoft’s line of networking and utility software products are engineered to empower users to effectively manage their data.

1989 - 2002

In the early 90’s, Prosoft utilized its extensive knowledge of device drivers and built an exhaustive device driver source code library. Prosoft licensed this library, known as Drive7, to Apple Computer and a number of other companies.

Seeing the benefit of products and working on Prosoft’s strengths in network engineering, Prosoft acquired NetWare for the Mac from Novell, Inc. in 1998. Prosoft’s NetWare for Mac was a success and exposed Prosoft to the benefits of becoming a products company.

In 1999, Prosoft made the plunge into creating its own products division, Radialogic LLC. Soon Radialogic released three products: Storage Master, built on the expertise of the previous Drive7; Chaos Master, a disk management product; and CD Master, a cutting edge CD authoring tool for Macintosh.

CD Master’s innovative technology was purchased by a large hardware manufacturer and developed into a major multimedia product used by millions of customers worldwide. You might be using it now on your computer! (purchase agreement forbids us from saying who actually bought the products but you might make a guess)

After CD Master’s acquisition, Prosoft refocused on its past strengths and devoted its resources to engineering services and creating future solutions for the NetWare product line.

In 2002, Data Rescue was released, launching Prosoft’s focus on expanding its product line and the move away from engineering services to a data recovery company.
