David Broughton stepped in at short notice for the first Wednesday meeting to deliver a talk

with the title "What DOS Can Do For Windows Users", originally scheduled for 2nd July. He

started with a short PowerPoint presentation that answered the question "What is DOS?" in

two ways. The first answer was that DOS (for Windows users) is like a stethoscope for

finding out what is really going on inside the computer as opposed to the gloss and spin that

users are presented with when using Windows.

The second answer was more prosaic: DOS was the original operating system for the first

IBM-PC brought out in 1980. It works by the user typing commands on a command line and

pressing Enter. Whilst primitive in operation, DOS has been gradually improved by Microsoft

over the different generations of Windows with the latest version that comes with Windows

XP being a considerable improvement over older versions. Help in using DOS commands can

be found by typing "/?" after the command where a summary of the command's operation can

be found with any of the extra enhancements. For example, the XCOPY command now

features an optional exclusion list. This is a text file of directories that are to be excluded from

the copy operation, useful when using XCOPY for backup operations.

@ECHO OFF

REM File: BU.BAT, 2003-06-02

REM A batch file to demonstrate a simple backup system using

REM the DOS program XCOPY supplied with Windows XP.

REM

IF EXIST D:\F1F2F3\NUL GOTO OK

ECHO Wrong CD in drive. Please replace with the backup CD in

ECHO current use. This must have a root directory named F1F2F3.

GOTO END

:OK

REM The following XCOPY command only lists the files -- it does

REM not copy them.

XCOPY C:\*.* D:\F1F2F3\ /S /A /M /F /L /EXCLUDE:C:\XFILE

ECHO The above list of files will be copied to the directory

ECHO \F1F2F3 on the CD unless you press Control C to abort.

ECHO Press any other key to continue.

PAUSE >nul

ECHO Copying Files...

XCOPY C:\*.* D:\F1F2F3\ /S /A /M /Q /Y /EXCLUDE:C:\XFILE

ECHO Done. Files copied to D:\F1F2F3

:END

Talk on DOS, 4th June

could never happen to me. That’s what

Isabel Robertson, a freelance writer who lives

on one of the islands of the Inner Hebrides,

thought. Having spent days researching and

writing an article for a key client, four hours

before the deadline she tried to open the file

from a floppy disk to send it by email. Her

computer refused to read the drive.

After trying a number of basic steps, it

became obvious that there were serious

problems and she was in danger of losing her

client. Because of the deadline, as well as the

fact that she was a day’s travel from the

nearest centre that could help her, Robertson

used the internet to find an emergency service

that could help. She accessed the remote data

recovery service offered by Ontrack and was

able to save her files – and her contract.

“Without Ontrack’s help I would have let the

client down badly. The Ontrack engineer was

brilliant and I was so impressed that I could

retrieve the data without leaving the house. I

would recommend the remote data recovery

service to anyone,” she said.

Your data lifeline

According to Todd Johnson, general manager

at Ontrack Europe: “Protecting information is

not just about restoring data in the event of a

crash, but also ensuring that you have plans in

place to keep it safe. Central to this is having a

proper procedure for backup, but the sort of

surgery required for full recovery of your PC

should also be complemented with regular

checkups that include virus protection”.

For André Post, senior researcher at

Symantec Security Response, it is all about

safe computing, which is not just software but

a way of thinking: “Make sure you have

antivirus software installed and kept up to

date, and preferably a firewall as well. Also,

keep all your software patched with the latest

security fixes to keep your system as safe as

possible. Last, but not least, use common

sense – for example, when receiving emails

from sources you don’t know.”

When is data disaster most likely to strike?

Most common are those incidents where, after

upgrading a piece of hardware or installing

new software, a conflict occurs and a carefully

balanced house of cards comes tumbling

down. Many people will perform a major

operation, such as changing to a new operating

system, without checking their backup systems

only to find that a vital piece of hardware or

software, such as a tape drive or backup

application, no longer works.

Computer rehab

The most important step for recovering from a

computer crash is to ensure that you have

backups of all your important data and

applications.

Disks and images

An alternative to this type of backup software

is to use disk imaging programs such as

Norton Ghost 2003 or PowerQuest’s Drive

Image (www.powerquest.com). These

applications create a compressed image of

your drive that stores all application, user and

system files and can be copied to CD. Should

your computer fail, simply boot from your

drive image to restore your system as it was

before the crash.

Hardware options are more varied; Probably

the most common form of backup, now that

the humble floppy has had its day, is the CD:

cheap enough and, with the latest CD-writers,

fast enough not to deter even the most

recalcitrant data savers.
