[Welcome]
Reynolds Marketing would like to thank you for purchasing our product. We feel
that this software package can alleviate some of the fear of loosing your
valuable data.
Reynolds Utilities are a collection of tools designed to prevent the loss of
valuable data on your hard drive. In the event that your hard drive data
becomes corrupted, excluding a catastrophic drive failure, you will be able to
recover from common DOS problems.
Most data corruption manifests itself in the form of damage to one or more of
the following areas of your hard drive:
o Partition Table
o File Allocation Table
o Root Directory
o Data Area
Conventional drive backups are a timely and costly process, due to the price
of the disks or tapes needed to backup all of the data files.
Reynolds Utilities was developed to be a quick and cost effective method to
insure data integrity. By backing-up only the areas of the drive prone to
corruption, you create for yourself a form of insurance policy for your data.
This software is not meant to be a replacement for conventional data backups,
but a companion to it, alleviating the need to perform backups as often.
[Navigation Keys]
When navigating through pull-down menu items, you may press the F1 function
key to get context sensitive help information at any time. When making
selections at input screens, use the Left and Right Arrow keys to make your
selections. Hot Keys are color coded red. If you have a mouse, you can select
a menu item by clicking on it.
[What is a Hard Drive?]
A hard drive is an electromechanical device used for the mass storage of data
(i.e. programs, word processing and database files). Data is written onto
rigid platters in concentric circles called tracks. Every platter has two or
more surfaces depending on the number of platters in the drive. The tracks on
the top surface have an identically corresponding set of tracks directly
underneath; and this follows for every platter in the drive. Track zero is
the outer most track on the platter. There is a corresponding track zero on
the underside of this platter and another on the top of the next, and so on.
All of the track zeros line up into a stack called a cylinder. There will be
a number of cylinders based on the number of tracks per surface.
For every surface there is a corresponding read/write head that magnetically
reads and writes the data on the disk. Tracks are divided into evenly spaced
units called sectors.
The read/write head positions itself, seeks over the data field of the sector
and either reads the data field or writes to it depending on the operation.
Each sector on the track holds 512 bytes of data. You can calculate the
capacity of the drive by using the following formula to establish the physical
drive configuration:
Capacity = Cylinders x Heads x Sectors/Track x 512 bytes.
[Physical vs. Logical Drives]
Reynolds Utilities performs actions on your drive in one of two ways, to the
Physical drive and the Logical drive. The physical drive refers to the hard
disk as a whole, in the form of cylinder, head and sector accesses, from the
very first physical sector on the drive to the very last.
Most users divide the drive up into multiple partitions, or logical drives. If
you have only one partition, the entire drive is logical drive C:, but if you
divide the drive in half creating two partitions, you will have logical drive
C: and logical drive D:. All accesses to logical drives are done in absolute
sector accesses, zero being the first and then being numbered sequentially to
the end of the partition.
In some cases you may want to only test, save or restore data to a single
logical drive or you may want to perform an operation to the entire physical
drive. It is imperative that you understand whether the operation is logical
or physical, so that you know whether the whole drive is involved or only a
portion of the drive.
[Getting Started]
To install Reynolds Utilities on your hard drive, type:
C: <ENTER>
MD RUTILS <ENTER>
CD RUTILS <ENTER>
COPY A:\*.* <ENTER>
Reynolds Utilities is now installed on your hard drive. To begin the program,
type the following information at the DOS prompt:
RUTILS.EXE <ENTER>
If you are using the keyboard, press the Right and Left arrow keys to
highlight a menu item and press <ENTER> to select it. You can also press the
first letter of each menu item to quickly select an item. If you are using a
mouse, click the left mouse button on a menu item to select it.
The first time you run Reynolds Utilities, your drive will be identified and
the configuration written to the disk in a file called RUTILS.CFG. This file
needs to be in the start-up directory each time the program is executed.
[Overview]
The menu bar consists of five categories of tools, as shown in Figure 1. When
you select one, a pull-down menu drops down, offering additional choices
related to that tool.
System The system menu choice provides tools for communicating
with DOS while in Reynolds Utilities. You can check the
drive configuration, search for files, execute a DOS
command or shell-out to DOS without leaving Reynolds
Utilities. Selecting About displays Reynolds Utilities,
including its version number.
Prevention Prevention tools are used to backup critical areas of the
drive prone to corruption.
Recovery This tool is used to restore those critical areas when
damage has been done to your drive.
Analysis The Analysis tool is used to test the integrity of your
drive should you become suspicious of its operation.
Automatic This is a quick and easy way to backup or restore all
critical areas of the drive, instead of doing them
individually.
These topics will be defined in the chapters that follow.
[System Tools]
Configuration
This is used by Reynolds Utilities to identify your drives physical geometry.
Drive C:, or drive 0, is the first physical drive in the system. Drive D:, or
drive 1, is the second physical drive in the system, if installed.
Reynolds Utilities uses this configuration for all accesses to the drive. All
drive copies or tests are performed using this geometry. It must be kept
accurate, or only a portion of the drive will be accessed.
Directory
Directory is used to do a quick directory of the drive without leaving
Reynolds Utilities. At the Directory window, input the file specification to
search for. Wild cards may be used.
Execute
You can execute any DOS command without leaving Reynolds Utilities. At the
Execute window, enter the DOS command you wish to execute. The program will
shell-out to DOS. When you are finished, type exit to return to Reynolds
Utilities.
OS Shell
Selecting the OS Shell will shell-out to DOS. When you want to return to
Reynolds Utilities, type exit.
Quit
Quit will return you back to the opening screen. Press the down arrow key to
exit, and press <ENTER> to return to the DOS prompt.
About
The About box is used to identify which version of Reynolds Utilities you are
currently running. Reynolds Utilities is a constantly evolving product, and
when calling for technical support, you will need to tell us which version you
are running.
[Prevention Tools]
Disk Test
The Disk Test feature is included within the prevention selection so that
logical drives can be quickly tested. The test is intended to insure the drive
is in good working order before performing other prevention selections.
If the operating system incurs a problem with the drive, it may perform
several retries without telling you. If the problem is a read error due to a
marginal sector or address mark, you may not want to use the area with the
problem. The information or data stored in this location may be unreadable or
corrupted. Unfortunately you will not be aware that a problem exists until
it's too late. The only way to insure your drive has not developed a problem
area is to perform a quick Disk Test. When Disk Test is selected, you are
testing every sector in the selected logical drive or partition.
To perform the test, select the Disk Test menu item.
The selection will prompt:
Logical Drive to Test?
simply press the right or left arrow key to make your drive selection
and press <ENTER>.
The display will be updated so that you can monitor the test progress. All
errors will be written to a file called DISKTEST.LOG, allowing you to record
the failure history of your drive.
Mirror
The Mirror selection is designed to save system and file allocation
information for logical drives. The File Allocation Table or FAT is a record
of where files are written on the drive. Files are located by following this
record. DOS may write a large file in one area or in many areas, wherever
there is free space. The FAT keeps track of thousands of file locations in
records called clusters. Problems with this record structure can prevent you
from accessing or locating previously saved files. A typical symptom of a
corrupted FAT is the computer may not start up or boot correctly because DOS
must locate COMMAND.COM and other important files needed to boot the system.
Some computer viruses will attempt to destroy information on a drive. They do
this by typically targeting the FAT and Root Directory areas in an effort to
change or erase the record of where your files are saved. When you perform
the Mirror selection, you create a copy of the FAT so if the records are
corrupted or destroyed you can restore the copy. We recommend performing the
Mirror selection after movement or changes in files. Many times, files are
read but not changed. DOS reserves space for files when they are written the
first time. For this reason, Mirror does not need to be performed unless there
are new additions to the FAT. Keep in mind that the Mirror keeps a copy of
your FAT; and when restored, the table will only reflect the records located
in the copy. Obviously, keeping it current can provide you with a great deal
of protection from common problems with DOS and computer viruses.
The reason this feature is different from other Mirror programs is that in the
Recovery selection you can Load Mirror information from your hard drive. The
Utility program performs a search of your hard drive to locate the information
rather than rely on the DOS record structure.
The Mirror, Save Root and Save MPH are performed when the Automatic Backup is
selected. This selection will automatically save the files to the Reynolds
Master working disk.
NOTE Additional information regarding the recovery of this file is contained
in the Recovery - Load Mirror section of this manual.
Save Root
The Save Root selection saves a copy of the Root Directory. Used in
conjunction with the Mirror feature, all file names and all sub directories
will match the mirror information. The Root Directory keeps a record of where
sub directories are located as well as file names and information pertaining
to each file. Computer viruses that attack the FAT will generally erase the
Root Directory as well.
The Automatic Backup selection will Mirror, Save Root and Save MPH to the
Reynolds Utilities Master working disk. Refer to the Automatic selection in
this manual for additional information.
Save MPH
The Save MPH selection saves a copy of the Master Partition Header. The
Partition Header contains the partition information for your hard drive. After
saving this once, you only need to repeat it if you change the partition or
add additional hard drives. The reason for saving a copy is the partition
information can be destroyed or corrupted very much like the FAT and root
directories.
If this happens, the most common problems you may incur are no partitions
defined or invalid drive specified. Both errors are easily repaired by
performing the Recovery - Restore MPH selection. Refer to the Recovery
selection in this manual for additional information.
Save Boot
This selection will save the boot sector information. The boot record stores
information pertaining to the formatted hard drive. DOS uses the information
when determining what type of device is installed. The boot sector information
is saved to a file called BOOTREC.
[Recovery Tools]
Load Mirror Data
This selection will search the hard drive for saved Mirror information. After
the Mirror is located, you can write the mirror to a file or to the hard drive.
If you're not sure if you want to write to the drive, simply choose the Write
to File selection. You can write it to the drive later.
When Load Mirror is selected you will be prompted for the following information
Source drive where mirror resides? Press the left or right arrow key to make
your selection, then press <ENTER>. Select the physical drive (C: for drive 0
or D: for drive 1), where the Mirror file is located.
Load Mirror for Drive? Press the left or right arrow key to make your
selection, then press <ENTER>. Type the logical drive letter for the mirror
you wish to restore. Press <ENTER> to continue.
Is this information correct? Press the left or right arrow key to make your
selection, then press <ENTER>. If you select NO, you will return to the
previous fields to change source drive or mirror to load. If you press YES, the
search will begin. At this point, you can escape by pressing the [ESC] key. The
search will scan the entire disk; therefore, it may take time to successfully
locate the appropriate information.
When the mirror information is located, you will be prompted to select one of
the following options: Write to File, Write to Disk or Quit.
WARNING! The Write to Disk and Write to File operations
will overwrite data on your hard drive. Verify your data
and backup before proceeding.
Write to Disk
The Write to Disk selection writes the Mirror information to your hard drive.
This feature writes to the reserved area DOS uses for the FAT.
Write to File
This selection writes the Mirror information to the Reynolds Master working
disk in a file called Newmiror.? The file extension will be a logical drive
letter such as C:, D:, etc. This allows you to save the file without having
to perform the search again if you do not have sufficient time to finish the
data recovery process.
Restore MPH
This feature restores the previously saved file called MPHDRV.? The extension
will be the physical drive the file belongs to; the reserved area where this
data is normally located. When this feature is selected, enter the physical
drive you plan to restore. You will receive an "Are you sure?" prompt. Select
"yes" before continuing.
The Restore MPH feature can be helpful when your computer incurs boot-up
problems and does not recognize its hard drive. Typical error messages include
"Invalid Drive Specified" or "No System."
The area where this data is stored is not normally accessible, so now you have
another helpful tool to solve DOS problems.
WARNING! The Restore MPH operation will overwrite data on your hard drive.
Verify your data backup before proceeding.
Restore Boot
Use this tool to restore boot sector information that is saved with the Save
Boot tool. The most frequent error you may encounter when there is a boot
sector problem is "Invalid Media Description Byte." This error can usually be
corrected by restoring the boot sector.
WARNING! The Restore Boot operation will overwrite data
on your hard drive. Verify your data backup before proceeding.
Sector Viewer
The Sector Viewer tool allows you to view the data stored on your drive. It
operates in an absolute read mode that allows you to view the areas of your
hard drive that are normally reserved for DOS. The Boot Sector, File Allocation
Table and Root Directory information is readable when traversing though your
hard drive.
When you select a valid sector, the first 256 bytes will be displayed.
To view the second 256 bytes, press the <PgDn> key. The <PgUp> key allows you
to return to the first 256 bytes.
If you want to browse though many sectors, press the <Ctrl> and <PgDn> keys at
the same time, or the <Ctrl> and <PgUp> keys to reverse directions. This
allows a faster inspection of sectors when searching for a specific area. The
Hot Key identifiers are near the bottom border and the Drive and Sector Number
identifiers are located near the top.
When interpreting the data, the hexadecimal values are on the left side of the
screen and the ASCII values are on the right. In the HEX window, the byte that
is in column 00, row 000 is the hexadecimal equivalent of the alpha/numeric
character in the ASCII window at column 0, row 000.
If the character is unprintable, meaning a character above ASCII value 127,
the character is represented as a period (.) instead of the actual character.
Disk Copy
The Disk Copy tool will create an exact duplicate of the hard drive or an
absolute copy. For this reason, the Source drive and the Destination drive
need to be configured the same. Reynolds Utilities does not perform any
buffering of the data being copied. The two hard drives do not need to be
physically the same, but logically the same. If the drive types in the CMOS
setup tables are the same, then you can quickly create exact duplicates of the
original.
NOTE Make sure the Select-Configuration has been updated to reflect both hard
drives. The Starting and Ending Cylinder fields are selectable. When it's not
necessary to copy the entire hard drive, you can easily select a variable
number of cylinders to copy.
This feature can be used to recover data from drives when you do not wish to
alter the original drive containing data. By creating a copy, the repair and
manipulation of files is performed on a drive that has been proven to be fully
functional.
The Disk Copy feature can also be used to create copies of hard drives to be
used as backup data. Technology today for tape backups remains much slower
than hard drive transfers, leading to less frequent data backups by computer
operators. With the Disk Copy feature, the entire hard drive can be copied to
a second hard drive in just minutes.
The copy is performed by absolute sector copies. So when the second hard drive
is configured as the only hard drive, it will contain all of the information
required to successfully boot-up. The Disk Copy feature can also be used to
copy data rather than performing software installations over and over when the
final configuration of computers is typically loaded with the same software
programs.
Track Copy
Similar to Disk Copy, Track Copy performs absolute copies and is very useful
when hard drives may not be reliable.
The Track Copy function is the easiest and fastest way to backup data files.
It allows disk-to-disk copies even when the system doesn't boot from the hard
drive. The track copier is much faster than Disk Copy because larger amounts of
data can be transferred.
Boot Information
This tool reads drive information that may be necessary in the successful
recovery of lost data. It shows the heads and sectors as well as other useful
statistics pertaining to the hard drive selected.
[Analysis Tools]
The Analysis menu provides several hard disk diagnostic routines to insure that
your disk is in good working condition. The test routines have been designed
to be fast and easy to use. Tests are performed sequentially or randomly. The
sequential test starts at sector zero and proceeds in a linear fashion to the
last sector on the drive. Random tests work the drive much harder, because of
the many long seeks involved. If you have an intermittent drive problem, it is
likely it will exhibit itself under the random test.
Read Tests
The Read Test selection performs read tests of every sector on the
drive, allowing you to identify grown or new defects. Use the arrow keys to
select the available options.
Any errors that are incurred are displayed in the "Display Error Log" window
below the test progress window The results are not saved unless the output
device selected is set to File. If so, all test results are saved to a file
when the test is completed.
Write Tests
The Write Test is used to identify new defects on the platters, or to test the
drive's write functionality. The same test options that are available in the
Read tests are available here (see Read Tests).
WARNING! The Write Test operation will destroy all data on
your hard drive. Verify your data backup before proceeding.
Seek Tests
The Seek Test is used to test the drives ability to correctly position
the read/write head(s) over a desired cylinder. The same test options
available in the Read tests are available here (see Read Tests).
Loop on Sector
This feature allows you to loop on any given sector when analyzing sectors with
test equipment. Loop on Sector will continue its operation until you strike
any key, then it terminates.
WARNING! Write/Read Compare will destroy all data on your hard drive. Verify
your data backup before proceeding.
Write/Read Compare
This feature performs write/read compare tests to insure the hard drive is in
good working condition.
Partition Information
This tool reads drive information that may be necessary to the successful
recovery of lost data. It shows cluster sizes and other helpful statistics
about the hard drive.
Recalibrate
The Recalibrate tool performs a BIOS disk command to test the recalibrate disk
command.
Reset
The Reset tool performs a BIOS disk command to perform a disk reset.
Test Drive Ready
This tool performs a BIOS disk command to perform a test drive ready.
[Automatic Tools]
The Automatic menu selections allow you to quickly and automatically backup or
restore critical portions of your hard drive.
Backup
When the Backup tool is selected, you will be prompted to insert the Master
working copy of your disk into drive A:. After the disk is inserted, press
<ENTER> and the Partition Table, File Allocation Table and Root Directory of
the selected hard drive will be backed-up to the floppy drive.
[Repair]
The Repair tool performs an analysis of the current hard drive. Based
on the results of the analysis, Reynolds Utilities will try to correct and
repair the damaged areas. When Repair is selected, you will be prompted to
insert the Master working copy of your disk into drive A:. After the disk is
inserted, press <ENTER> and the Partition Table, File Allocation Table and
Root Directory will be written back to the selected drive.
NOTE The Repair feature should always be performed before using the Load Mirror
feature for data recovery.
