Many years ago I ran into a similar problem.  A technician came in to the office to replace my hard disk with a larger one, and instead of copying my old data to the new one, he started copying the new disk to the old one, resulting in &#x2F;home now being partially NTFS and partially ext2.  ie, it was unreadable in linux and Windows.  I documented the recovery process here: <a href="http:&#x2F;&#x2F;tech.bluesmoon.info&#x2F;2004&#x2F;11&#x2F;home-is-ntfs.html" rel="nofollow">http:&#x2F;&#x2F;tech.bluesmoon.info&#x2F;2004&#x2F;11&#x2F;home-is-ntfs.html</a><p>Bonus: a year later, at a different company, I was faced with having to undelete source files on FreeBSD (UFS).  I documented that as well here: <a href="http:&#x2F;&#x2F;tech.bluesmoon.info&#x2F;2004&#x2F;08&#x2F;undelete-in-freebsd.html" rel="nofollow">http:&#x2F;&#x2F;tech.bluesmoon.info&#x2F;2004&#x2F;08&#x2F;undelete-in-freebsd.html</a>
