All users of GoBack should read the following. This document is
also available in GoBack Help.
It is important to realize that, although GoBack adds an
underlying safety net to the use of your computer, it is not a
replacement for backups. In many situations, GoBack will be
able to restore your entire computer or a specific file that
would otherwise be lost. However, this ability should not be
assumed. GoBack's restorative ability is a function, among
other things, of the intensity of disk usage and the amount
of disk space allocated for tracking.
A tutorial about the unique features and abilities of GoBack
can be launched from the GoBack Main Menu.
Should you wish to do so, GoBack can only be correctly
uninstalled using Add/Remove Programs (click Start, Settings,
then Control Panel).
The following are important issues relating to the use
of GoBack.
- MS-DOS Compatibility mode
MS-DOS Compatibility mode is a mode in Windows 95/98/Me
in which your hard disk(s) are not operating optimally
using Windows 32-bit drivers, but are instead using
MS-DOS real-mode drivers.
If GoBack detects this condition, GoBack will not
install or run. You must correct the problem before
running GoBack. There can be many reasons that a
hard disk is running in MS-DOS Compatibility mode.
These reasons include, but are not limited to:
- An "unsafe" device driver, program, or virus
loaded in Windows memory.
- A hard disk controller not detected in Windows.
- A conflict between the hard disk controller
and another device.
- An incompatible hardware device or configuration
in Windows.
- A damaged Windows driver.
Because GoBack does not cause the MS-DOS Compatibility
mode condition, you must consult your hardware
manufacturer for information about correcting the problem.
You can also find many detailed articles about
troubleshooting MS-DOS Compatibility mode problems in
the support area on the Microsoft web site.
- Drive support / device drivers
GoBack can protect all drives that are recognized by the
BIOS. If your drive is not recognized during the
initial BIOS hardware identification phase of the boot or
requires special device drivers you will not be able to use
GoBack with that drive. GoBack does not protect removable
media, like diskettes, Zip, etc.
- Using disk partitioning utilities
With GoBack installed you can still use partitioning
utilities to manipulate your hard disk's partitions.
However, before you use any of these utilities you must
disable GoBack (from the GoBack Main Menu, click Options,
then Disable GoBack). After you have finished modifying
your hard disk's partitions, re-enable GoBack.
The following programs are known to modify disk
partitioning: Partition Magic, Partition-It, Ontrack
Disk Manager, and EZ-drive.
- Installing or moving hard disks
Before installing or moving a hard disk, disable GoBack
(from the GoBack Main Menu, click Options, then Disable
GoBack), install the drive, then re-enable GoBack. If you
want GoBack to track the new hard drive's events you will
need to uninstall GoBack (using Add/Remove Programs in
Windows Control Panel) then re-install GoBack.
- Operating system compatibility and upgrading
GoBack is compatible with all versions of Microsoft
Windows 95, Windows 98, and Windows Me (Millennium
Edition). This version of GoBack does not support
Linux, OS/2, Windows NT, or Windows 2000
(note: a Windows NT / Windows 2000 version of GoBack
is forthcoming).
When upgrading to a new or different operating system,
GoBack should first be uninstalled. An appropriate
version of GoBack that supports the new operating
system should then be obtained and installed.
- Using disk compression utilities
GoBack is not supported on drives compressed with a
disk-level compression utility (such as DriveSpace,
DoubleSpace, etc.). However, GoBack is fully compatible
with file-level compression, such as that provided by
PKZIP, WINZIP, and ARJ.
- Booting from floppy disks
With GoBack installed you can still boot from floppy
disks. However, you must ensure that GoBack drivers
are loaded. These will allow you to access your hard
disks. To boot from a floppy, start by booting your
system from the hard disk. In other words, without yet
inserting the floppy, restart your PC. When the initial
GoBack screen appears, press the spacebar, then insert
your floppy disk and then click the Boot from floppy
option.
- More about "Safe Points" and file recovery
GoBack automatically creates "safe points" surrounding
various events like saving a file. You can select a
safe point either before or after an event in order to
see your disk at these respective times. The file
recovery systems in GoBack utilize safe points in order
to retrieve otherwise lost files. GoBack requires about
ten seconds of hard disk inactivity between operations
(like saving a file) in order to distinguish the two
events. Thus, if you save a file, quickly make a change
and then save it again within about ten seconds there
is a chance that GoBack will not be able to recover the
interim revision. However, revisions at earlier or
later safe points are still recoverable.
GoBack is not a replacement for traditional backup
program. However, if you have a non-hardware failure,
GoBack will generally be able to save the day.
- Disk activity, performance, and restorative ability
In most situations involving disk activity, such as
saving a file, GoBack will not noticeably impact the
computer's performance. However, it will add some
background disk activity that is involved with
re-optimizing and ensuring your changes transition
safely to the disk (part of its unique protection
against data loss). If you have made many changes to
your disk in a short amount of time, you may notice
the added background disk activity. However, it will
complete in time but, because it is done in the
background, you can continue to use and/or shutdown
your computer.
- How GoBack works and the theory behind it
GoBack works by adding a protective level between the
operating system and your hard disk. GoBack tracks all
the changes that are made to the disk. It contains
special logic to avoid data loss in the event of a
sudden crash or power loss. Because it is keeping track
of all your changes made in the recent past, it can
reconstruct your disk at virtually any point - a "safe
point" - in the recent past.
Safe points are moments in time where your disk is idle for
about ten seconds. GoBack allows you to return your disk to
an earlier state (reverting) or view and/or recover
specific files from the past (by referencing back to moments
when your disk was idle). Using a portion of the disk to
track recent changes, it is very likely that GoBack can
restore your computer to working order or retrieve an
otherwise lost file. This ability is provided without
generally impacting your computer's performance.

within any of the GoBack applications or in the User's Guide.
