Norton Utilities

The initial 1982 release supported DOS 1.x and featured the UNERASE utility. This allowed files to be undeleted by restoring the first letter of the directory entry (a workaround of the FAT file system used in DOS). The UNERASE utility was what launched NU on its path to success. Quoting Peter Norton, "Why did The Norton Utilities become such popular software? Well, industry wisdom has it that software becomes standard either by providing superior capabilities or by solving problems that were previously unsolvable. In 1982, when I sat down at my PC to write Unerase, I was solving a common problem to which there was no readily available solution."[1]

14 programs were included, on three floppy disks, list price $80:[2][3]

• UnErase, recovers erased files
• FileFix, repairs damaged files
• DiskLook, complete floppy disk displays and maps
• SecMod, easy changes to floppy disks
• FileHide, interactive hidden file control
• BatHide, automatic hidden file control
• TimeMark, displays date, time, elapsed time
• ScrAtr, sets DOS to work in any colors
• Reverse, work in black on white
• Clear, clears the screen for clarity
• FileSort, keeps floppy disk files by date or name
• DiskOpt, speeds floppy disk access
• Beep, causes the PC speaker to beep
• Print, prints files

The main feature of this DOS 2.x compatible version was FILEFIND, used for searching for files. This 1983 release added hard disk support, and the PRINT program was renamed LPRINT to avoid conflict with the DOS command introduced in MS-DOS 2.0 as PRINT.COM.[4] Following this release Norton became Utilities Editor of PC Magazine.[5]

The executable files were compressed with Realia's Spacemaker.[6][7]

This version, copyrighted 1984 but dated 21 January 1985, included Beep, Directory Sort, Disk Test, File Attributes, File Find, File Size, Line Print, List Directories, Screen Attributes, System Information, Text Search, Time Mark, Volume Label, Wipe Disk and Wipe File.

This 1986 version added the Quick UnErase (QU) and Unremove Directory (UD) programs.

Norton Utilities 4.0 for DOS

Release 4.0 (1987, list $99.95) added four new programs:[8]

• Ask, used for batch file programming
• File Info, add descriptions up to 65 characters long to each file
• Norton Change Directory, displays a graphic directory tree; change, remove, rename or make directories
• Norton Integrator, a menu system to tie the utilities together. Previously the utilities were accessed by typing the command name (usually a cryptic 2 character name such as FF) at the DOS prompt.

This version (list $150), released simultaneously with 4.0 standard edition, was dated 15 May 1987. It added Speed Disk, a disk defragmenter, and Format Recover.

Norton Integrator from Norton Utilities 4.5 for DOS

Norton Disk Doctor was the major addition in this 1988 release.[9] It also includes Wipedisk; Wipefile, a Batch Enhancer and a sector level disk editor; a system information diagnostic utility and a disk caching program (NCACHE), which was between 10 - 50% faster than Microsoft's SMARTDrive when properly configured.

Release 5.0 added new features, including Disk Editor, a utility to perform low level formatting on hard disks and changes such as password protection on the more “dangerous” utilities. It also included a licensed version of the 4DOS replacement for COMMAND.COM called NDOS. This version also allowed the choice of “classic” names (such as FF.EXE) or longer names (such as FINDFAST.EXE); these were configurable in the updated version of the Norton Integrator menu system.

Norton Utilities 6.0 for DOS

Norton Utilities 6.0 supports DOS 5 and Windows 3.1. It includes Windows Program Manager support, but the tools are still DOS-based, so a set of icons were supplied.

It includes Norton Disk Doctor, Disk Editor, Disk Tools, Speed Disk, Norton Cache, Disk Monitor, Diskreet, NDisk, System Information, NDOS.[10]

The speed of Speed Disk was improved over the previous release.

Diskreet supports Data Encryption Standard.

System Information now includes more detailed information on installed system.

UnErase takes advantage of DOS 5.0's Delete Tracking and Mirror File features to recover data.[11] However, MS-DOS 5.0 added a new UNDELETE.exe program, licensed from Norton competitor Central Point Software,[12] which took advantage of the same Delete Sentry control and Deletion-tracking files. (The ERASE command is an alias for the DEL (Delete) command in the DOS command line). Windows 95's Recycle Bin soon further reduced the need for UnErase.

Release 7.0 supports MS-DOS 6.0, DoubleSpace, Stacker and SuperStor disk compression tools.

Tools includes Norton Disk Doctor, Disk Editor, Undelete, SmartCan, NDOS, System Information, File Find, Norton Change Directory.[13]

Speed Disk remained as well, although SPEEDISK.exe was licensed by Microsoft and incorporated into MS-DOS as DEFRAG.exe in MS-DOS 6.0 onward.[14]

Release 7.0 had revised user interfaces for the utilities that feature a menu-driven user interface. Also some of these tools now did not need to run in full-screen-mode but just displayed a window in the center of the screen, like the disk formatter or the disk duplicator utility.

Disk Editor now includes Advanced Recovery Mode.

Release 8.0 was nearly the same as 7.0, but added Windows 3.1 utilities.

DOS Utilities include Norton Disk Doctor, System Information, Change Directory, FileFind, Diskreet, DUPDISK, File Fix, NDOS, Batch Enhancer, Norton Integrator, Speed Disk.[15]

CD-ROM version was announced on 15 January 1996.[18] It adds Disk Companion, Memory Companion and Norton Utilities Companion over floppy disk version.

Disk tools included with this release are not compatible with FAT32.

The Windows version of Speed Disk works with much greater speed than Microsoft's supplied defrag program, as it moved groups of clusters, not single clusters as Microsoft's Windows Disk Defragmenter. Changes in the way Windows operates meant that many of the old utilities were either dropped completely or replaced with GUI based versions. However, with the advent of Windows XP onwards, Norton's Speed Disk reverted to single-cluster defragmentation.

Version 2.0 was announced on 7 October 1996.[19] Version 2.0 features Norton CrashGuard with Anti-Freeze, Norton System Genie, Norton AntiVirus, LiveUpdate, System Genie, Registry Editor, System Doctor, System Benchmark, Disk Benchmark, Multimedia Benchmark, Speed Disk, Space Wizard.[20]

It includes Norton Disk Doctor, Norton Speed Disk, Norton System Information, Norton System Doctor, Norton Protection/UnErase, Live Update.

Norton Disk Doctor, Speed Disk support FAT16 and NTFS file systems.

This version added 64-bit support on Windows XP and Vista. It includes Registry Defragmenter, Registry Cleaners, Disk Cleaner, Disk Defragmenter, Startup Manager, Service Manager, Restore Center, System Optimizer, Process Viewer, and Performance Test.

The product license was changed to allow the software to be installed on up to three household PCs.

PC Pro rated Norton Utilities 14 with 1 star (out of 6) for “an overpriced collection of optimization tools that falls far short of its promise.[38] IT Reviews called the package “light on features compared to rivals” and it questioned the “usefulness of some of the monitoring utilities.[39]

PC Advisor criticized Norton Utilities 14 for delivering “little that you can't already do with Windows”, although it did acknowledge that it brought two things to the table: “The registry tools, which are useful, and the performance monitor, which is interesting but not always useful.”[40]

When Apple released System 7, Norton Utilities for the Macintosh needed to be updated in order to run safely. This proved to be a recurring story in the history of the utility; early versions were highly regarded for a while, but proved to be hazardous when used with newer disk structures and operating systems before being updated.

On 17 January 2012, Symantec admitted to their network getting hacked. A hacker known as “Yama Tough” obtained Symantec's source code by hacking an Indian Government server. Yama Tough has released parts of the source code, and has threatened to release more. According to Chris Paden, a Symantec spokesman, the source code that was taken was from enterprise products that were between five and six years old.[75]

On 25 September 2012, eight months after the first hack, an affiliate of the hacker group "Anonymous" published the source code for Norton Utilities. Symantec has responded that this was from the same code leaked in January 2012. They have confirmed that the leak included source code for 2006 versions of Norton Utilities, pcAnywhere and Norton AntiVirus.[76]

In June 2018 Steve Gibson alleged in his weekly podcast "Security Now!", that Norton's Disk Doctor was not created by Norton but instead was reverse engineered from his ubiquitous SpinRite software without permission or attribution. This, he says, occurred after he refused to accept Peter Norton's bid to purchase SpinRite from him. He claimed proof in that random numbers he generated for BIOS checking were left unchanged in Disk Doctor presumably because Norton's software engineers didn't know their purpose. Also Norton eventually abandoned Disk Doctor as they didn't really understand how it worked so couldn't actually support it for users.[77]
