Simple enough. But the damaged drive was still giving me problems. I should have used the boot CD to kill it there. But instead, like a maroon, I booted into Windows &#038; and tried to just &#8216;add&#8217; the disk in the disk manager.<br \/>But somewhere in my sleepiness after a 16+ hour day I converted my Windows 7 drive to a dynamic volume that included the messed up drive!<br \/>Before I realized what I had done it was too late.<\/p>\n<p>What to do?<\/p>\n<p>With the damaged drive not working my &#8216;dynamic volume&#8217; was now in accessable after restarting the machine!<br \/>So on with the searching for a solution.<br \/>I read over and over how a Dynamic Disk could NOT be converted back to a Basic Disk.<br \/>Even Microsoft say this is so!<\/p>\n<p>But I knew I had read somewhere about editing the MBR and setting the drive back to basic year ago. I may have even done it.<br \/>And after many days and many hours I found a simple elegant solution in an old post that WORKED!<\/p>\n<p>I simply pulled out the affected Windows 7 drive and used my HDD dock to attach it to one of my main machines and edit the MBR sector to change the disk back to a Basic Disk.<\/p>\n<p>Basically it involves using a freeware hex <a href=\"http:\/\/mh-nexus.de\/hxd\/\">disk editor<\/a> to open the MBR and just change one sector(sector 0 location 1C2) value from &#8217;42&#8217; to &#8217;07&#8217; saving the change. Then running a check disk and fix (chkdsk x: \/f).<br \/>I put the drive back in booted and after a few moments of &#8216;recovery&#8217; at start up my entire OS was back!<br \/><a href=\"http:\/\/www.wilderssecurity.com\/showthread.php?t=191006\">Here is the post.<\/a> <\/p>\n<p>It is very detailed and easy to follow.<br \/>I hope no one needs it but if you do this is good to have in your tech notes file.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Here is the story.
