  <BODY>



    <H1>myrescue harddisk rescue</H1>



    <P>See also our <A

    href="http://sourceforge.net/projects/myrescue/">Sourceforge

    Project Page</A></P>



    <H3>Description</H3>



    <P>myrescue is a program to rescue the still-readable data from a

    damaged harddisk. It is similiar in purpose to dd_rescue, but it

    tries to quickly get out of damaged areas to first handle the not

    yet damaged part of the disk and return later.</P>



    <H3>Note:</H3>



    <P><B>This tools is no replacement for a professional <A

    href="http://www.google.de/search?q=data+recovery">data recovery

    service</A>!</B> If you do have the latter option, don't even think of

    using myrescue, as it may further damage your disk. This tool is

    provided only for the case that you are absolutely desperate and

    definitely cannot afford a professional data recovery. Or in case

    you know what you are doing, e.g. if you know that it is the aging

    of the magnetisation layer that is causing your problem.</P>

    <P>The usual GPL disclaimer applies. Especially the NON-WARRANTY OF

    FITNESS FOR A PARTICULAR PURPOSE. Don't blame (or sue) me if it

    fails to recover or further damages your data.</P>



    <H3>How it works</H3>



    <P>The program tries to copy the device blockwise to a file and

    keeps a table ("block bitmap") noting whether a block has been

    successfully copied, not yet handled or has had errors. This block

    bitmap can be used in successive runs to concentrate on the not yet

    rescued blocks.</P>



    <P>The program has a special skip mode to handle read

    errors. Usually harddisk surface defects cover more than just one

    block and continuous reading in defect areas can damage the surface,

    the heads and (by permanent recalibration) the drive mechanics. If

    this happens, the chances of rescuing the remaining undamaged data

    drop dramatically. So in skip mode, myrescue tries to get out of

    damaged areas quickly by exponentially increasing the stepsize. The

    skipped blocks are marked as unhandled in the block bitmap and can

    be retried later.</P>



    <P>Finally, the program has an option to multiply try to read a

    block before considering it damaged.</P>



    <H3>Share your experiences</H3>

    <P>The developers are glad to hear about your experiences. Please

    post them to the <A

    href="http://sourceforge.net/forum/forum.php?forum_id=235860">Experiences

    forum</A>. Thank you!</P>

    <P>The project has already had beta status for quite a long time

    now. I have not received any bug reports, but also very little

    positive feedback. If it worked for you, <EMPH>please</EMPH>

    let me know, so I can promote the project to "stable".</P>



    <H3>Status</H3>

    <P>The (beta) release 0.9.4 can be downloaded from the

    <A

    href="http://sourceforge.net/project/showfiles.php?group_id=68256">Files</A>

    Section on our Sourceforge Project Page.</P>

    <P>The package still lacks 

    <CODE>./configure && make && make install</CODE>-style

    installation and any portability considerations. Volunteers?</P>
