It was showing up in the hardware list in windows, but no data recovery program I ran could access it. Testdisk could see the disk, but not recover data from it.<\/p>\n<p>I installed Ubuntu linux on another machine, and set up and ran ddrescue. It took several WEEKS to complete, but it managed to recover all but 28.8 mb&#8217;s of data. That&#8217;s over 99.98 percent of the data! This is really an excellent result.<\/p>\n<p>Part of the reason why I am posting this is because, during my research, I could not find any reference to ddrescue taking this long. I came across examples of ddrescue taking days, or maybe a week, but never this long.<\/p>\n<p>Some users of the program might be inclined to cancel ddrescue after a few days, believing it to be a lost cause, but it is important to realise that with this program data recovery can take several weeks or more!<\/p>\n<p>After I got the data back, it turned out that the MFT (Master File Table) on the drive was completely destroyed, and I was unable to mount and copy files in the usual way. However, conventional data recovery programs like <a href=\"http:\/\/www.z-a-recovery.com\/\">Zero Assumption Recovery<\/a> were able to easily recover what seems to be all of the data on the disk.<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>ddrescue\u00a0is a linux based tool for recovering data from failed or failing hard disks.
