    copy files to CD-RW in DOS

    Hello ,

    My HDD cannot boot up due to a virus.
    I would like to backup the files in DOS (obviously l can use the DOS copy command and copy the files to a floppy disk) but is there an easier way.
    i.e A way of copy the files a CD-RW?

    If not what would be the easiest DOS command to copy some files to a floppy disk as it will take a good few floppy disks to backup some essential files before l re-format the hard drive. Is is xcopy or copy. I cannot remember the parameters.

    Any help would be much appreciated as l sending this on behalf of a friend who cannot use his PC due to the HDD beind down.

    Regards.
    Justin

    Re: copy files to CD-RW in DOS

    I haven't come across any DOS software that will copy to a CD-RW. There again, I have never been faced with that need.

    Attached is a text file showing the parameters for the xcopy command in Windows XP. Hope this helps.

    Cheers, Bob

    Thanks for that.

    Just a few questions is is possible to copy files than will span over several disks and prompt when asking for a new
    disk and also how can l specify only files ending in a certain extention. i.e *.jpg and which are in all subdirectories of the root directory.

    Re: copy files to CD-RW in DOS

    Googling brought out a utility called XXCOPY that can be found here. It comes in 2 flavours and has a span parameter. Please note that I have no experience with this product so I suggest you visit the site to find out more information. The site does have a link to show the 200+ switches.

    Regarding your question about file selection... the COPY and XCOPY functions provide selective features for wild cards. For example COPY *.JPG would deal only with JPG files. Of course you can include folder names (sub directories) such as COPY C:Pictures*.JPG. I assume that the above mentioned product, XXCOPY would also have wild card capability.

    Re: copy files to CD-RW in DOS

    Hi Justin,

    I was only addressing your "copy" issues in previous replies. However, I did not ask if you have tried any AV products to try and eradicate the virus on the HD. Symantec for example, can scan for problems from their CD. The down side is that the AV definitions would only be as current as the date the CD was initially created and might not help for a current rendition of a virus.

    Another question... when your friend did try to boot, what message was popping up to indicate a virus? If the actual virus was known it might be possible to download a fix to a safe PC and run the scan from a bootable diskette.

    Cheers, Bob
    Regards,
    Bob

    Re: copy files to CD-RW in DOS

    Hi ,

    Virus type is unknown as when when PC boots up desktop is shown with no taskbar or icons.
    Also mouse driver does not work when PC boots up.
    He had AVG installed l don't really know of another solution as windows does not boot up properly (not even in safe mode)
    Is there a decent DOS anti-virus program on the market which is freeware that you know of?

    If not l will resort to backing up disks and re-format HDD.

    Justin.

    Re: copy files to CD-RW in DOS

    I have never come across a free, DOS based AV program that is capable of scanning for the thousands of viruses that exist. There are many free DOS based AV scanners that seek out and destroy a single known virus. These are usually available from some of the more prominent AV software suppliers like AVG, McAfee, Symantec etc. but of course you need to know which virus you are trying to eradicate.

    Based on your description of the problem, I am not 100% convinced that the PC has a virus. It sounds like more of a hardware issue. If there are many applications installed or many personal data files, I would try to determine if there was a hardware problem... before taking the drastic step of reformatting.

    Is it possible to create a bare bones system and try to acquire a successful boot? For example, just leave the hard drive, video card and remove other pieces of hardware like the sound card and any other equipment that is not essential to the boot process. I would certainly try that before reformatting.

    Looks like you might have an "interesting" weekend project!!! <img src=/S/smile.gif border=0 alt=smile width=15 height=15>

    Re: copy files to CD-RW in DOS

    Hi Justin

    For the purpose of booting clean into DOS, from AV floppies, I'd recommend the following (successful from personal experience), provided it's suitable for your particular Windows O/S. Download and install the following small program to a clean PC:

    Art's F-Prot DOS interface, updater and emergency program for Win 9x/ME - F-Pup.exe

    --- Version 1.8B created on 3/31/04 ---
    Download F-Pup.exe on a clean PC running Win 9X/ME. The FP-UP.EXE program contained within the self extracting archive will download the latest version of F-Prot for DOS antivirus and update the DEF files. You can create a Emergency Boot Disk (EBD) set to be used on the ailing PC. This set consists of a special system boot disk plus two antivirus disks.

    FP-UP.EXE provides the user with a convenient point-and-click interface program for routine use as well as emergency use.
    Drag the FP-UP.EXE icon to the desktop and create a shortcut.

    You'll need 3 formatted, empty floppies for the emergency boot disk set. Make sure they're all WRITE-PROTECTED when you use them on the infected PC.
    The F-Prot AV program is highly regarded, and the DOS version is <img src=/S/free.gif border=0 alt=free width=30 height=15> for personal use, as is Art's nifty updater.

    Good luck with it.

    Alan

    Re: copy files to CD-RW in DOS

    Using XXCOPY from DOS (the XXCOPY16 program) certainly does have issues, since it does not support long filenames (LFNs). There is a clunky workaround detailed as Q4 here but it's still messy. It seems OK if you can later run XXCOPY from Windows to reinstate the LFNs to the 8.3 names. I definitely wouldn't use it if you expect to use the backup to replace the originals... definite <big>BIG</big> problems.

    Re: copy files to CD-RW in DOS

    You could try loading the hard drive as a second drive in a working machine to back up the data. As long as you didn't let anything execute...

    Some AV products come with a command-line scanner. I assume this works at the command line you're describing, but I suppose it's possible that it only works when Windows loads first. I don't have any direct experience with such products.

    Re: copy files to CD-RW in DOS

    If you have a proper XP install disc you could install a second copy in another folder like "XP" and access your folders and files that way. I also belive this sounds like more of a hardware issue causing a software problem.
